Using Gradle with IntelliJ - intellij-idea

We are trying to setup a number of Gradle (v1.5) web projects in IntelliJ v12.1.2
The new JetGradle integration works fine until we get the the Artifacts
The module is imported as a Gradle project, the artifact is been created as a Web Application (Exploded) and the Web facet has been added - all the dependencies that are declared in the build.gradle file are correctly added to the WEB-INF/lib directory in the artifact
The problem comes when we make a change to the dependencies in the build.gradle file and refresh the module using the JetGradle refresh button - the dependencies of the module are updated correctly but nothing is changed in the artifact
If we changing just one dependency then the change can be done manually but if there are a number of changes or there are a lot of new/changed transative dependencies then it seems the only timely way to get the correct dependencies in the artifact is to delete and recreate it
Am I missing something obvious, does anyone know a better way to update the artifacts
Thanks

Automatic artifact config update is not implemented yet. I've created corresponding ticket for that - http://youtrack.jetbrains.com/issue/IDEA-109369

How to add a jar to the external library for a project w/o disappearing after sync and with imports working?

Presently having an annoying time getting a jar added to the external library for the project, then in turn not disappear when syncing and the imports working. Adding I figured out and answered in another question. The issue is to keep persistent and accessible to a jar I create within the project for import.
I am not sure if I am missing a step or forgot to set something. I am using a modified gradle (forgegradle) to create the project. Have not found a solution with the documentation, or any for IntelliJ yet. I am generally new with IntelliJ, choosing to use it instead eclipse which I have previously used.
The goal is a to create an add-on for a mod to another jar. The main jar already in the external library from the start, now attempting to add the mod to it. I could modify the mod, but it is not my code, so rather not simply modify it directly and repackage it.

If you are using an external build tool / system that syncs with IntelliJ it is recommended to use that build tool / system to add dependencies.
IntelliJ will always take a backseat, and treat the build tooling / system as the source of truth for the project model as best it can.
You mention you are using gradle, I would recommend adding the dependency as a managed dependency that is, let gradle download it from a repository, and resolve the dependency/library itself.
If you can not do this, and you can't host a repository yourself, The next best recommendation I have, is creating a 'libs' folder inside the project, that contains jars that can't be found in repositories (They may be mods or plugins that were never published)
You can read up on how to add a library folder to gradle here: How to add local .jar file dependency to build.gradle file?

IntelliJ, JRebel, Maven and a JEE 6 application

My setup is
IDE: IntelliJ
Application: JEE6 with an EAR and a WAR module
Build: Maven
Hot-Code-Replacement: JRebel
App-Server: Glassfish 3.1
I configured the application in IntelliJ in a way that the ear gets deployed. The ear "target" folder looks like this
target/classes/
target/appEar/appWeb-version-Snapshot.war/
target/appEar/lib/
target/appEar/META-INF
In the default configuration JRebel listens for changes in the classes/ folder.
When I change something in the web module, and build this, the classes are only updated in appWeb/target/classes/ but not in appEar/target/appEar/appWeb-version-Snapshot.war/.
If I want to update those classes I have to select "Build Artifacts" in IntelliJ after building the project.
To sum up, I have to do these steps for a hot code replacement:
(once) Configure JRebel correctly.
Make project
Build Artifacts
This whole procedure appears to be too complicated to me. Does anyone have a clue how to setup IntelliJ/Maven/Glassfish/JEE/JRebel correctly? I have not found an example containing all my tools. I'd like to have only one action for the code replacement, not two.
There's "build on make" checkbox in your project artifact settings, that will always recreate your artifact on compiling, if that's what you are looking for. However JRebel should remap where your application is reading class files and resources based on rebel.xml, so you probably should just rewrite rebel.xml to look for classes where they are compiled to, not where they end up after building the artifact.
Why do you need to Build Artifacts every time?
Your war should contain the rebel.xml that maps to the classes in /target/classes folder.
When you make changes to said classes, your server then knows to load the changes from those classes.
So you only need to build your project in order to see the changes assuming your rebel.xml classpath points to /target/classes.

Play 2 dependency on a local module in Intellij Idea

I am kind of new to PlayFramework 2 and can not figure out how to resolve play 2 application dependencies. I need to add dependency on a local module loaded in IntellijIdea, not a jar file or repository.
While adding module dependencies in Idea project setting works just fine and ide itself is able to resolve them (autocompletion, imports etc are working), when trying to run in play2, its compiler cannot resolve any dependencies.
I manually configured Build.scala (adding val appDependencies = Seq("" % "" % "")) but am puzzled as to what resolvers I should use. I cannot point to a jar file, as it is a work in progress and such a file should be updated too often. Doing so would defeat the whole purpose of managed dependencies.
Play's main build mechanism uses SBT, which needs to know how to find all sources required for the build. There are several options for this:
make your module an SBT project itself and publish it to your local ivy repository. However that might be somewhat complex at this stage, and would involve adding your local ivy repository to the resolvers and re-publishing every time you change something in the module
declare your module as a sub-project. Play's documentation describes the process of working with sub-projects, I think this is the way you'd like to try out since then the idea command on Play's console will generate the IntelliJ configuration for the main application and the module.

Eclipse RCP: Dependencies correct (?) but get a NoClassDefFoundError

I have a RCP project where I cannot fix a NoClassDefFoundError: One plugin depends on another plugin. The plugin-dependencies are set in the manifest, packages exported, and there is no error at compile time. Both plugins are in the product dependencies and visible in the installation details of the product.
But when I run the application I get a java.lang.NoClassDefFoundError when the one plugin wants to use a class from the other plugin.
Any hints how to find the reason for this are greatly appreciated.
Thanks,
Michael
I found the problem: I created the plugin which could not be loaded from an existing Java project. And somehow I deleted the "." in the entry Bundle-classpath in the plugin manifest (the plugin has some jars which -> so lib/xyz.jar was in the Bundle-classpath entry but not the ".").
For the class-loader of the bundle the "." means to search for classes from the root path of the bundle (or something like that), so it could not find the classes. However, there were no errors in the IDE so it was hard to find.
Is the configuration for running the application correct i.e. all dependencies are also put in the running configuration?

How to configure IntelliJ IDEA and/or Maven to automatically add directories with Java source code generated using jaxb2-maven-plugin?

In our project we are using jaxb2-maven-plugin to generate Java source code from XML Schema, which causes that our Maven module requires additional source code directory (in our case target/generated/main/java). Up to date I've been using Eclipse and maven-eclipse-plugin to import all the projects into Eclipse workspace. The plugin is (somehow) able to add the directory with generated source code automatically to Eclipse' .classpath file.
Recently I try to switch to (play with?) IntelliJ IDEA 9 (so I am a newbie in this environment) and I've noticed that additional source directory is not added during IDEA's importing process...
Is there any way I can configure IDEA/Maven to make importing directory with generated source code automatically?
The convention with Maven is to generate code in target/generated-sources/<tool>, for example target/generated-sources/jaxb2
Follow this convention and IDEA will add the folder as source folder (see IDEA-53198).
Generated code, using jaxb2-maven-plugin, was missing for me in Intellij 2017.1 whereas Eclipse Neon created it.
Fixed it from context menu of module by selecting 'Maven -> Generate Sources and Update Folders'.
Try with maven-jaxb2-plugin. If it does not work then it's IDEA problem.
In Maven you can add new source roots per configuration. Maven plugins can do this programmatically. This is for sure the case with maven-jaxb2-plugin. Then, if IDEA does not recognize it, then it's a problem on that side.
You can use the Maven Build Helper Plugin. It is located at http://www.mojohaus.org/build-helper-maven-plugin/
It allows to configure additional source roots. And the maven integration of IntelliJ will add the new source root. We are using this feature in quite a few builds and it works just fine. Tested with vers. 13 of IntelliJ IDEA.
