Maven reads user configuration from wrong location - maven

I just discovered why Maven doesn't work properly on my machine. For some reason it reads the user configuration from the completely wrong location. And I don't understand why. When I run maven with the -X switch I get the following output in the beginning:
[DEBUG] Reading global settings from D:\dev\maven\active\conf\settings.xml
[DEBUG] Reading user settings from D:\.m2\settings.xml
[DEBUG] Using local repository at D:\dev\maven_repo
Why is it reading user settings from D:\.m2 and not my actual user directory like it normally should? It worked fine on my old computer. Does it have something to do with me having installed maven on a different drive this time? On my old computer it was installed on the C drive.
Where does it get this D:\.m2 from? How can I make it read the user settings file from the actual default location, %userprofile%\.m2?

Finally figured it out. Found the solution in this blog post. To find the home directory in Java you do this:
System.getProperty("user.home");
Problem is, for some dumb reason, Java isn't using Windows environment variables or anything like that to find this path. It actually uses the parent directory of the Desktop directory. Since I like to keep certain main folders in my user directory on a separate drive (documents, downloads, music, desktop, etc) I had moved the desktop directory to D:\Desktop. Java then takes that directory, goes one level up and makes Maven and other java applications think D:\ is my home directory.
Gotta say the more I use Java the more i hate it... anyways, hopefully this might help save some hours of head scratching for someone else too.
Update
The original blog post is gone, but found on the WaybackMachine (the URL has been updated), but here's the gist from that post in case that goes too...
The issue: So how does Java play into all of this? Well, Java
developers sometimes want to store settings for their applications in
a folder within the user’s profile directory. It’s the Linux way, and
Java tends to do things the Linux way. (As mentioned earlier, Windows’
“AppData” folder servers the same purpose, with some extra separation
for data dependent on whether or not it should roam with the user’s
profile.) For some reason, Java does not use the Windows environment
variable to determine the location of the user’s profile, but instead
access a registry key that references the user’s desktop folder. It
then takes the parent directory of the desktop and assumes that is the
user’s profile folder (assuming the user makes use of the default
setup Windows chooses).
Essentially, when a programmer calls the Java command:
System.getProperty("user.home");
Java uses the following idea to determine where my user profile folder
is:
PATH_TO_DESKTOP_FOLDER_AS_SET_IN_THE_REGISTRY + "\..\"
This breaks down when the desktop folder has been modified.
So, with my setup, instead of saving settings at:
c:\users\tim\
Java apps tend to save data to:
t:\tim\
In reality, Java apps should save settings to:
c:\users\tim\AppData\Roaming\
or something like that.
To add insult to injury, the Java apps continue to follow the Linux
way and use a period at the beginning of the folder name in an attempt
to “hide” the folder (as is done on Linux). For Windows users, this
simply ensures these folders are listed first in directory listings.
(Hiding a folder on Windows is achieved through setting the hidden
attribute for the file.)
It looks like NetBeans has addressed the issue for their application,
but the root issue remains an unresolved, low priority bug. Somehow
I’d bet it would get fixed a lot faster if the mechanism for
determining the user’s home path on Linux was wrong.

getting the DLLs in the application's home directory to be called upon instead of the registered DLLs

Yes, I know vb6 ancient and all that. It's still an interesting question. and the issue might not even be with vb6....
Background: We have a server running a vb6 application for our users who access this via Citrix. This installed application accesses its DLLs (also written in vb6) from a "shared folders" location.
What I want to do is have the previous version of this same app on the same server, accessing it's own set of (previous versions) DLLs. I am half way successful. the renamed app in another directory runs. But it crashes immediately upon using any feature that draws from the DLL's code.
Apparently the registered DLLs of the current version are being called upon. I dont want that. I want the DLLs found in the same directory as the renamed older app to be called upon.
Can that happen in a windows server? is this an installer's settings issue? Have you ever had this situation before? were you successful?
thanks in advance.
Harry
Post Script:
The bosses decided that experimenting with the DLLs and system settings was a waste of my time and not worth the risk. So they're throwing money at it and another server will come online for the sole reason of providing the previous version to the citrix users who want it. Thank you to all of you who pitched in with great tips and leads to other posts. (yeah I'm sort of disappointed too. Kind of wanted to know what the solution was to this.....)
The OS should be looking for the dll’s in the following places and order
The directories listed in the App Path registry key (HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionApp
Paths) if any
The directory where the executable module for the current process is located
The current directory
The Windows system directory
The Windows directory
The directories listed in the PATH environment variable
Given that you are using a shared folder for your dll’s, I would suppose that the app is setting the current directory to your shared folder OR is using the PATH environmental variable to specify where to look. I don’t think it is using the app path registry key path because that is version specific and you said you are using a different version.
I would suggest your try setting the path via HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionApp Paths

ClickOnce Error "different computed hash than specified in manifest" when transferring published files

I am in an interesting situation where I maintain the code for a program that is used and distributed primarily by our sister company. We are ready to distribute the program to all of the 3rd party users and since it is technically our sister companies program, we want to host it on their website. (in the interest of anonimity, I'll use 'program' everywhere instead of the actual application name, and 'www.SisterCompany.com' instead of their actual URL.)
So I get everything ready to go, setup the Publish setting to check for updates at program start, the minimum required version, and I set the Insallation Folder URL and Update Location to "http://www.SisterCompany.com/apps/program/", with the actual Publishing Folder Location as "C:\LocalProjects\Program\Publish\". Everything else is pretty standard.
After publish, I confirm that everything installs and works correctly when running directly from the publish location on my C: drive. So I put everything on our FTP server, and the guy at our sister company pulls it down and places everything in the '/apps/program/' directory on their webserver.
This is where it goes bad. When I try to install it from their site, I get the - File, Program.exe.config, has a different computed hash than specified in manifest. Error. I tested it a bit, and I even get that error trying to install from any network location on our network other than my local C: drive.
After doing the initial publish in visual studio, I have changed no files (which is the answer/reason I've found by doing some searching about this error).
What could be causing this? Is it because I set the Installation Folder URL to a location that it isn't initially published too?
Let me know if any additional info is needed.
Thanks.
After bashing my head against this all weekend, I have finally found the answer. After unsigning the project and removing the hash on the offending file (an xml file), I got the program to install, but it was giving me 'Windows Side by Side' Errors. I drilled down into the App Cache were the file was, and instead of a config .xml file, it was one of the HTML files from the website the clickonce installer was hosted on. Turns out that the web server didn't seem to like serving up an .XML (or .mdb it turns out) file.
This MSDN article ended up giving me the final solution:
I had to make sure that the 'Use ".deploy" file extension' was selected so that the web server wouldn't mangle files with extensions it didn't like.
I couldn't figure out why that one file's hash would be different. Turns out it wasn't even the same file at all.
It is possible that one of the FTP transfers is happening in text mode, rather than binary?
For me the problem was that .config transformations were done after generating manifest.
To anyone else who's still having trouble, five years later:
The first problem was configuring the MIME type, which on nginx (/etc/nginx/mime.types) should look like this:
application/x-ms-manifest application
See Click Once Server and Client Configuration.
The weirder problem to me was that I was using git to handle the push to the server, i.e.
git remote add live ssh://user#mybox/path/to/publish
git commit -am "committing...";git push live master
Works great for most things, but it was probably being registered as a "change," which prevented the app from installing locally. Once I started using scp instead:
scp -r * user#mybox/path/to/dir/
It worked without a hitch.
It is unfortunate that there is not a lot of helpful information out there about this.

Logging into TFS on a Mac

I got Team Explorer Everywhere so we can use TFS on the Mac Mini we got to test Iphone apps. Since we're using XCode for phonegap, we need to use the commandline program and it is giving me a lot of grief.
What I've done so far (Listing out for anyone who stumbles on this so they can use it):
-Downloaded the trial (free)
-Set the path using PATH=$PATH\:/FOLDERLOCATION
-Accepted EULA and got trial product key... for command line program (tf eula/tf productkey -trial)
-Set up workspace:
tf workspace -new WORKSPACENAME -server:http://SERVERNAME:PORT/FILEPATH -comment:"WORKSPACENAME" && prompted for username -> domain -> password
-Trying to setup the folder path (Fixed):
tf workfold -map SERVERFOLDERPATH LOCALFOLDERPATH -collection:http://SERVERNAME:PORT/FILEPATH -workspace:WORKSPACENAME && prompted for username -> domain -> password
-Make sure I can check out/check in (On hold):...
The error I'm getting right now is "An argument error occurred: First free argument must be a server path." This is what I've been following ever since I got the path set, but I think the versions are different because mine doesn't seem to be set up the same. Any help at all would be appreciated, and I'll keep up with the post as I figure parts out because there doesn't seem to be much online that I can find on TFS on macs.
Update: As normal, I'm an idiot. Have to put the options at the end of the command and have to have the serverfolder path as the first thing after -map. Now I just need to figure out how to use the damn thing. I'll post any other questions I have and try to get all the correct commands up for the selfish reason of having them somewhere in case I forget them later.
Update 2: The mapping hasn't worked out as well as I'd hoped, it seems a combination of my unfamiliarity with Unix/Mac file systems and some settings being missing is keeping me from using 'tf get' to load all of the test data I was trying to get. I'm planning on trying again after I get the location of where my boss wants the data saved and after I can look into something that would save the workspace so it won't say that it can't find the map path every time...
It looks like you're setting up your workspace and some working folder mappings just fine, after the edit. If you're having problems doing a tf get after this, then there are some common problems that might be occurring. TFS workspaces can be a little bit opaque and having a better understanding of them can sometimes help you understand where the problem is:
Team Foundation Server requires a workspace to be configured before you can get files out of source control, edit them or check them back in. A workspace basically simply contains working folder mappings that map your local path(s) to server path(s).
Workspaces are stored on the server and are uniquely identified by your computer's hostname, your username and the workspace's name. A cache of this information for the local host is saved on the client. This implies:
If you remove a workspace on the server, your workstation will be unable to connect.
If you remove the cache, your local computer will not be able to identify the workspace based on working folder mappings until the cache is rebuilt (which happens every time you connect to the server.)
If you change your username or local workstation's name, you cannot access those workspaces.
(Note that very early versions of the Teamprise command line client had certain issues on Mac OS that made identifying the local workstation name difficult. This is fixed, however, in Team Explorer Everywhere.)
Because you can have multiple workspaces for a single server on a single workstation, you can't always simply provide server paths to tf commands, since server paths are ambiguous. ($/ exists in every workspace, for example.) So the command line client resolves paths based on the current working directory and/or the arguments provided. Meaning that you can run tf get foo.txt if you're in a working folder, or you can run tf get /tmp/foo.txt if /tmp is mapped.
One more point - the configuration data for Team Explorer Everywhere is shared between the TFS plug-in for Eclipse and the command line client. So if you're more comfortable using a GUI to set up your workspace(s), you can do that and then use the CLC as you see fit. You don't need to be a Java programmer to use Eclipse - simply download Eclipse and install the TFS plug-in for Eclipse into it, and select Window > Open Perspective > Team Foundation Server Exploring. After that, you'll have the full GUI Team Explorer experience and this perspective will be restored when you open Eclipse, so you won't even need to worry about the Java IDE bits if you don't want to.

Where should a WinForm app keep its logs?

I am working on a WinForm application, that allows working to work with "projects" (think about the application as Visual Studio, and projects as VS Solutions).
My question is - where should the application keep its logging files?
Some requirements include:
the application might not be running as an administrator (so saving in the %ProgramFiles% installation folder is not a good option)
The logs should be accessible to end-users (either for review, or for sending to the support team). (This means that hard to find folders, like %AppData%\Company\Application\Version\ProjectName... are not a good solution either)
The application might generate logs even when there are no open projects (so saving the logs in the project's folder is good only when there's a project, but not a final solution).
I was thinking of creating a "working folder" when the application is installed - something along the lines of C:\Application\, and then save the logs in a subfolder, like %WorkingFolder%\Logs\ProjectName
Thanks for the input.
Somewhere in the user's directory is actually the correct place to store them if they are specific to the current running user.
Some programs create folders at the top level of the User's directory, next to Documents and Desktop, others do it in Documents.
Creating it in C:\ might cause issues if the user doesn't have write access to the root directory. You can pretty much guarantee the user will have write access to the Home directory.
The other option is to look for an environment variable, and if its set use the value as the location, if not default to the User's home directory.
If the logs are user only you should store them at %AppData%\Company\Application Name.
If the logs are shared (any user can see any log) you should store them at:
%ProgramData%\Company\Application Name (for Vista+)
or
%AllUsersProfile%\Application Data\Company\Application Name (for XP-)
As for user access, you can add a shortcut to the start menu to the appropriate location or have a link within the program.
Another option in Vista+ is the Public folder (%Public%) which has links throughout Explorer for easy access to.
Where should I write program data instead of Program Files is a good blog entry by Chris Jackson from Microsoft. While it isn't an "official stance" it holds some excellent information.
You can always ask the user to configure this. Set a default path, maybe the application directory. During installation or while setting up the application you may prompt the user to input the path they want to use for logs. That's fair, right. If they're advanced enough to use logs they're good enough to configure a path too.
What do you plan to do with the logs. Are they technical, of for financial/security audits?
The EventLog is a nice place for technical logs, because you can access it remotely (within the Domain) and it is cleaned up automatically.
The %AppData% is also a good place for technical logs, specially if you are unable to connect to the eventlog. You can find the log files, and you can direct the end-user to them, but they are not "in the face" of the end-user. You can include a "send log to the maker" button to receive them.
For logs that needs be accessed by end-users, the My Documents (or a subfolder) looks good.
You can just to add button / menu item to easy open folder with logs.
Best place fo logs are %AppData%\AppName or %temp%\AppName.
Never use %MyDocs% or %Program Files%.
I'd suggest adding that question to the installer so that the user that installs the software can decide where best to put the logs. Though C:\[AppName\ sounds like a reasonable default for your requirements.
Edit: Just thought off, it would probably be worth warning the user if the select a bad location (in Program Files or in the root of the system drive etc) and if they choose to create a new directory, automatically give that directory correct permissions during the installation.
I think %APPDATA%\YourCompanyName\YourAppName is the preferred location. To overcome your stated objection of this location being hard to find, you could pretty easily and quickly implement a simple support screen in your app to allow the end user the ability to access and email these logs without too much trouble, so that the user will not have to remember or manually navigate to the long path name to get to the logs.
I don't really like the idea of the user being able to set this location via the installer because of possible naming and permission issues.
If the app needs to maintain the log only for the users current logged in timespan, then you could keep it in c:/temp.
Most of my winapps, i leave it there, so automatically it gets deleted once the user logs off..
Ofcourse, this primarily depends on your requirement.

What is the best default location for projects in Visual Studio?

Over the years I have vacillated between having my project/source folders in a directory one level removed from the root (e.g. D:\Projects) and keeping them in the default location for Visual Studio.
In the past, I resisted storing anything in the various "My Documents" folders established by Win 95, Win 98, and XP. I finally switched to storing them in the Documents folder since Vista shortened the path and I got tired of changing default directories for my dev tools. However, now I find myself leaning toward creating a folder off root again since I am setting up a new machine.
I get tired of the long paths you have to navigate to when stuff is stored in the documents folders. Also, I don't backup source code and database files like I do with my other documents since I use a VCS for source code. However, it seems you are always fighting to maintain a "non-standard" source location since every dev tool generally wants to store stuff in a subfolder of documents.
I would like to hear other's opinions on this subject.
I think it depends on your use... I prefer to have my development projects on a separate drive/partition, so will usually use the following convention D:\projects\{company-name}\({client-name}|internal)\{project-name} Where the client-name comes into play is when the work is by a given company, but for another. I keep my projects under D:\projects\personal\... This allows for a better structure.
As to backup strategies, imho this is what source control is for. I prefer subversion, and have a backup strategy for the svn server. Although I didn't much care for ankh 1.x, the 2.x version, along with TortoiseSVN have worked pretty well for me. As a matter of practice, I tend to checkin often, and try to only checkin code in a runnable state (though new features/code may not work).
In clear violation of my Unix past I use c:\dev (for development) or whatever other drive I use for development. Note: It is advisable NOT to use the system partition for development as software development really fragments the disk.
I never had any reason to use another directory - except for some projects where "company standards" forced everybody to have the development directory on the root of the C: drive. (really! They had hardcoded paths to c:\whatever)
During development I sometimes check out multiple versions of the source to different directoies - if only to find out that the version committed into the version control system of the day really has every file checked in. (Sometimes I add a file to the development directory but forget to check it in.)
So I think it is rather irrelevant where your development directory is, as long as the path is typable for you (I prefer short paths) and does not contain white space for the usual reasons on windows (if you want to do some scripting).
I preferred location at another partition. Because projects have many and many small files and if you use SVN or other revision control system this files have very high fragmentation and slowing system if are storing at OS partition.
I haven’t tried it myself, but I guess you can put your projects in My Documents and use a symbolic link to the directory in your root folder. By doing that you can access your files both ways and solve problems like changing directory for tools. Info about symbolic links in Vista
If you’re the only one using your computer I don’t really see why you should put your code in the profile directory, backup should be done using a version control system anyway.
I store "active" projects on a secondary drive, one level from the root. It's much more easy to get quickly to that folder (even if VS2008 has this nice "Open Folder in windows explorer" now). It's also convenient for backups, format/reinstall, etc. The "less active" projects are stored on a NAS for quick reference. All are also stored on a remote SVN server that is backuped. (I'd also recommend not using # in folder for web application as it (sometimes) create strange errors from the development web server)
I use SUBST (run on startup) to map some random folder to a high-lettered drive. Then I can put my stuff anywhere, and move it around, and yet I always get to refer to it by Y: or Q: or whatever.
This is one of those extra layers of indirection that are said to solve every problem.
For personal projects I just put them on the desktop (although I do move the desktop to D:\Desktop). They are archived off to my documents when they become inactive.
For work I have all the projects in a C:\Sourcecode folder inside a dedicated development virtual machine.
Just one question, do your primarily develop desktop apps or web apps?
If you are constantly writing web apps, here's what works for me:
Create a folder: c:\dev or c:\sites (keep it simple)
Register the folder as a virtual directory in IIS
Create a different folder for each of your projects and create a web application in IIS for each of them
One advantage this setup might have is that, its easier for you to navigate your site in the browser, i.e less typing, easier to remember, standardization for all your other apps.
my 2cents.
it is better to keep your project in the other partition else than window and i think as i do
d:\projects\"some grouping of project own your own choice"\projectname
e.g.
d:\projects\UNIversty\admission
d:\projects\universry\examination
d:\projects\planners\ipp
