Does anyone know how to use maven jetty:run with filtering? I've seen some other answers using other maven goals (jetty:run-exploded) but these don't let me modify my html pages on the fly without restarting.
Thanks.
afaik, with jetty:run it uses the source code's files, not the target.
you might need to run replacements on your source code files in a phase before you start jetty.
if you dont want replacements on your source files, i think you're stuck with run-exploded
I found the solution and posted an answer to my own stack overflow question, FYI: How to filter resources when using maven jetty plugin?
Not sure whether I should duplicate that post, but I can if that's a requirement for acceptance.

I need to convert few projects from ant to maven. I know the basics of both, also read a lot of articles on how to. However, is it a good idea to write a pom using eclipse? Or is it better to write it without using eclipse? The M2Eclipse plugin needs maven to be tweaked more, will the changes related to M2Eclipse cause problems when the war is built on jenkins?
Pros of using Eclipse IDE:
The formatting of pom.xml will be taken care, when you add the 'maven-eclipse-codestyle.xml' to the code formatter, as mentioned here. Formatting will be harder when you do it without an IDE.
The auto-completion feature of eclipse will make your coding easier, since it will automatically sense the open tags and close them. You need to close all the open tags manually, if you don`t use an IDE.
You can view the dependency hierarchy of the dependencies added and hence it might be a bit helpful while managing the dependencies.This can be extremely useful ,when you have transitive dependencies (Dependencies within other dependencies). You can find more about transitive dependencies here.
An IDE will warn you of common mistakes that may occur while coding (something like, 'forgetting to close an open tag','placing a tag in an incorrect location'). This will save a whole lot of time. If you don`t use an IDE, you need to correct the mistakes only when you get an exception after executing a maven command.
Eclipse will warn of missing artifacts (when the dependencies are not present in the local repository), which can help you to fix it before executing the maven goal.
Cons of using Eclipse IDE:
m2e plugin will throw 'Plugin execution not covered by lifecycle configuration' errors all over your pom.xml files. These errors won`t affect your build, but may be quite annoying.
I personally have done migration from Ant to Maven2. IMO it is better to write pom.xml on your own so that you wont face any last minute surprises as well as you will get complete overall knowledge on what you are exactly doing with your pom file.
However if you still want to go with m2e, from my experience it did not create any problems at all. Regarding the build - I guess there shouldn't be any issue. You can refer this link if you need more info about m2e and jekins - m2e and jenkins
I understand that the maven-compiler plugin is used to compile the code. Some of my project does not have that plugin in the pom file? When is it required?
I am trying to answer my own question based on what I learned since posted this question. If this answer is correct or incorrect please comment. Thanks.
If this plugin is not defined, the Maven Super POM contains all the default plugins you will be using. It works fine for small and non-serious projects. However, the best practice is to define these plugins in a company-wise POM and so that when you upgrade maven, you would not end up using a different version of plugin.
Have a look at the Goals Overview Section in Apache Maven Compiler Plugin
The Compiler Plugin has two goals. Both are already bound to their proper phases within the Maven Lifecycle and are therefore, automatically executed during their respective phases.
You only have to add it if you want to change the default parameters
I want to sftp the binary generated after build (if build is successful) is completed to a different server using maven. Please suggest how this can be done?
I want to edit pom.xml to achieve this.
Build system is maven. Please not that file is to be copied on different server
Thanks
You typically described a perfect use case for the Wagon Plugin.
I am working on a project and using Maven to build it. The project is a quite big Java web application and it is supposed to work with both Mysql and Oracle databases.
The problem is that there are some specific annotations related to either of the two databases in the source code, plus some other differences, so that I am forced to manually comment/uncomment part of the code before building the application for one of the two databases.
Basically what I would like to achieve is to have my build script, maybe via a Maven profile, to automatically switch the source classes before building depending on the database I want my war to work against.
Putting it simply, the idea is to have MyClass.oracle and MyClass.mysql, and depending on my build profile I should move one of the two in the source dir, rename it MyClass and build. This should be done for some packages, classes, and also configuration files.
Is there any way I can achieve it via "pure" Maven? The only solution I came across till now is to use an antrun plugin and reference an Ant build.xml inside of it.
Thank you,
Mattia
A pure maven solution would be to develop your own maven plugin. Depending on your requirements this can be an overkill, however it is not hard at all, you can see how to achieve this here.
This is a limitation of Maven. One of Maven's purposes is to not have a build script. You should simply use the plugins as available, and setup your project the right way, and magically, everything will build!
There is one solution: Use Ant. Well, not to redo your whole project with Ant, but with the antrun plugin, you can run a few Ant tasks at various phases of your Maven build life cycle.
It's been a long, long time since I've used this, so I am not going to try to write a test pom.xml, but I don't remember it being very difficult to use.
Of course, the correct Maven solution is to divide your project up into "common core" code, and then a separate Oracle and MySql client that uses the "common core". By the way, I hope you're not patching source code. Instead, you're using a properties file to do this for you.
I'm trying to embed jetty in a war file so I can launch it frcom the command line, but I'm struggling. I'm using maven, has anyone done this before?
Thanks! Steph
I don't know if you already did this, but as far as I remember, you need to copy all dependencies that are provided in your war file as direct dependencies of the jetty plugin.
