scald.rb results in error (could not find or load main class) - ruby

I am trying to run the tutorial files from https://github.com/twitter/scalding/tree/develop/tutorial.
I cloned the 0.17.x branch and current develop branch and haven't had much success with either.
I have also already ran "sbt update" and "sbt assembly" to create the fat jar which is used by this scald.rb script.
Upon running the command below from the root scalding directory
scripts/scald.rb --local tutorial/Tutorial0.scala
I receive either of these errors:
Error: Could not find or load main class Files
[SUGGESTION]: Try scald.rb --clean, you may have corrupt jars lying around
or
Error: Could not find or load main class scala.tools.nsc.Main
[SUGGESTION]: Try scald.rb --clean, you may have corrupt jars lying around
Whatever I try to do I cannot get the scald.rb script to work. I have tried the clean option and many other stackoverflow answers such as setting scala_home in my environment variables and path to scala/bin. Many versions of sbt/scala and nothing works.
Current Software:
-Ruby 2.4.2-2-x86
-sbt 0.13.15
-Scala 2.11.8
-scalding 0.17.x branch

Unable to Install Facebook Duckling on Windows - Stack Exec Fails

I'm trying to setup Facebook Duckling on Windows 10.
When I execute: stack exec duckling-example-exe it produces the following error:
duckling-example-exe.EXE: /etc/zoneinfo/: getDirectoryContents:findFirstFile: does not exist (The system cannot find the path specified.)
I don't understand why I'm getting this error since I followed the recommendation on this GitHub thread which suggests replacing "/usr/share/zoneinfo/" in Duckling/exe/ExampleMain.hs with a link to a folder containing the zoneinfo files. You can see I replaced the path as suggested in the screenshot below:
I also tried adding a double slash as seen below - but it didn't help:
I tried with forward slash instead but this didn't help either:
Moreover, I don't understand where the path: /etc/zoneinfo/ is coming from, if the path is no longer present in ExampleMain.hs? Where is the compiler pulling the path from?
Thanks!
You need to run stack exec duckling-example-exe in the directory where the stack.yaml and project.yaml files of the duckling source code is that you are trying to modify. Otherwise it will use the version of duckling from stackage without your changes.

Joomla "Fatal error: Cannot redeclare jblogerror() in on line 0"

Here is a weird problem i'm facing; after updating Joomla to the latest version, website failed to up load but, as i've made a backup manually from these folders:
administrator
bin
cli
components
includes
layouts
libraries
modules
plugins
yt-assets
and all the root files, after restoring the backup still the website is not loading and just says
"Fatal error: Cannot redeclare jblogerror() in on line 0" !
Any suggestion? Thank you.
Apparently, the version of jBlog you are using is loading its attempting to load its own classes twice.
Let's assume the jBlog developers already fixed it and you carelessly ignored the warning to ensure all your extensions are compatible before updating.
Are you able to access administrator? Simply go there and upgrade jBlog including any modules.
Else, the issue lies within a plugin. In order to access the administrator and perform the update, you will need to manually disable the offending plugin.
A simple way is to rename its folder: start from plugins/system then plugins/content hopefully you'll have spotted it by then. Look into the subfolders of each and spot any that may be relevant to jBlog (or grep through the folder to locate the specific string)
If you have console access, simply run
# grep -rl jblogerror plugins/system
and you should see all the files that include such string, just rename their main plugin folder. But you could also do all this through ftp and guessing.

go-swagger restapi/configure_todo_list.go - api.TodoGetHandler undefined error

I am a newbie in go and go-swagger. I am following steps in Simple Server tutorial in goswagger.io.
I am using Ubuntu 18.04, swagger v0.25.0 and go 1.15.6.
Following the same steps, there are a few differences of the files generated. For instance, goswagger.io's has find_todos_okbody.go and get_okbody.go in models but mine does not. Why is that so?
Link to screenshot of my generated files vs
Link to screenshot of generated files by swagger.io
Starting the server as written in the tutorial go install ./cmd/todo-list-server/ gives me the following error. Can anyone please help with this?
# my_folder/swagger-todo-list/restapi
restapi/configure_todo_list.go:41:8: api.TodosGetHandler undefined (type *operations.TodoListAPI has no field or method TodosGetHandler)
restapi/configure_todo_list.go:42:6: api.TodosGetHandler undefined (type *operations.TodoListAPI has no field or method TodosGetHandler)
The first step in goswagger.io todo-list is swagger init spec .... Which directory should I run this command in? I ran it in a newly created folder in my home directory. However, from the page, it shows the path to be ~/go/src/github.com/go-swagger/go-swagger/examples/tutorials/todo-list. I am not sure whether I should use go get ..., git clone ... or create those folders. Can someone advise me?
Thanks.
This is likely the documentation lagging behind the version of the code that you are running. As long as it compiles, the specific files the tool generates isn't so crucial.
This is a compilation error. When you do go install foo it will try to build the foo package as an executable and then move that to your GOPATH/bin directory. It seems that the generated code in restapi/configure_todo_list.go isn't correct for the operations code generated.
All you need to run this tutorial yourself is an empty directory and the swagger tool (not its source code). You run the commands from the root of this empty project. In order not to run into GOPATH problems I would initialise a module with go mod init todo-list-example before doing anything else.
Note that while the todo-list example code exists inside the go-swagger source, it's there just for documenting example usage and output.
What I would advice for #2 is to make sure you're using a properly released version of go-swagger, rather than installing from the latest commit (which happens when you just do a go get), as I have found that to be occasionally unstable.
Next, re-generate the entire server, but make sure you also regenerate restapi/configure_todo_list.go by passing --regenerate-configureapi to your swagger generate call. This file isn't always refreshed because you're meant to modify it to configure your app, and if you changed versions of the tool it may be different and incompatible.
If after that you still get the compilation error, it may be worth submitting a bug report at https://github.com/go-swagger/go-swagger/issues.
Thanks #EzequielMuns. The errors in #2 went away after I ran go get - u -f ./... as stated in
...
For this generation to compile you need to have some packages in your GOPATH:
* github.com/go-openapi/runtime
* github.com/jessevdk/go-flags
You can get these now with: go get -u -f ./...
I think it's an error of swagger code generation. You can do as folloing to fix this:
delete file configure_todo_list.go;
regenerate code.
# swagger generate server -A todo-list -f ./swagger.yml
Then, you can run command go install ./cmd/todo-list-server/, it will succeed.

appledoc Exception: at least one directory

After wasting some time to figure out what goes wrong, I finally have to ask for help. I want to use appledocs from Gentle Bytes. I followed every step of the quick install guide, but I´m not able to compile the project.
Here is what I´ve done:
1. cloned it from git://github.com/tomaz/appledoc.git
2. installed the templates to ~/Library/Application Support/appledoc
3. tried to compile the project
Everytime I try to compile, I get following error:
ERROR: AppledocException: At least one directory or file name path is required, use 'appledoc --help'
What do I have to do now?
Sounds like you've compiled it just fine and are now running the program. If it's a command-line program try command-option-R in Xcode to provide some arguments (i.e. names of files that you want to process).
The error means you didn't give it source paths: after all switches, you must give it at least one path to your source files. Can be either file or directory. In later case it will recursively scan the dir. Here's example
appledoc <options> ~/MyProject
Above example will use ~/MyProject directory as a source. You can also add multiple source paths. Note that you need to give the tool few options, see this page for minimum command line and other usage examples.
You either have to copy appledoc executable to one of directories in your path, as suggested by Caleb, or use full path to it when invoking (for example: /path/to/appledoc)

Path Error running CakePHP's "cake" console utility in Windows

A while ago when I started with Cake, I managed to get the console running in my Windows environment, and I have no idea how. I'm now having problems to make it work again in another computer.
This is what I've done in the new machine:
Downloaded my Cake code from source control (so all the files are exactly the same as the computer where it worked, including the configuration files)
Added PHP and "c:\my_cake_path\cake\console" to the path
If I run "cake OneOfMyShells", either standing on the /app, or in /cake/console directories, I get the following error:
Warning: get_object_vars() expects parameter 1 to be object, null given in C:\my_cake_path\cake\libs\model\connection_manager.php on line 199
Error: Missing Database Connection. Try 'cake bake'
"cake Bake", if run normally, when I try to get it to do the DB config ends up throwing another error (which is not that relevant to this)
However, if I run: cake bake -app "c:\my_cake_path\app"
Then bake works, I can do the database config, and it writes the DB config file (which is useless at this point, since I already had one)
Then, of course: cake OneOfMyShells -app "c:\my_cake_path\app"
does work perfectly well.
So, everything's working fine, I just need to manually specify the path to "app" every single time, which is very annoying.
How can I get around this? Where is Cake looking for to find the path to app?
Thanks!
Daniel
Not much of a difference in the sense you still need to type but you can run cake from the app dir like this: C:\XXX\project\app> ..\cake\console\cake.bat
To make it smaller you can put that line on a .bat or just add the \cake\console dir the windows path
