How to configure IntelliJ IDEA and/or Maven to automatically add directories with Java source code generated using jaxb2-maven-plugin? - maven-2

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.

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?

How to see dependency tree for JARS in IntelliJ using SBT

I am using intelliJ IDEA 2017.2.5 for spark-scala using SBT.
i have many dependencies jars but i wanted to know that which jar is getting downloaded or coming along BECOZ of which jar.
For example i have specified Jar_1 in my build.sbt file. Now when the project is built using SBT, along with Jar_1, multiple jars like jar_1.1, jar_1.2, jar_1.3 also gets downloaded. Now when i click on jar_1.3 or jar_1.2 i don't see the directory or any tree like structure which shows that its a child of Jar_1.
This feature is present in Eclipse. Attaching the image which shows this kind of Hierarchy.
As you can see the jars and also it shows that because of which jars it was downloaded. I need to know that whether such thing is available in IntelliJ if yes how to use it
It's not possible in IntelliJ IDEA for the SBT based projects at the moment, please vote for this feature request.

Is it possible to configure file types mapping in Idea via gradle 'idea' plugin

A little intro:
I work on a project with legacy codebase witch uses internal xml based descriptors with specific file extensions (about may be 10 extensions).
Let it be *.desc, *.check etc.
To have code highlighting for such a files I can configure Idea to consider these types of files as XML.
It's available through:
Preferences / Editor / File types
And then add all custom extensions to 'Recognized file types': 'XML'
Our project uses gradle as build tool
and my question is:
Is it possible to make same configuration via dsl of gadle 'idea' plugin?
The short answer is: No.
One could create a custom Gradle task that will modify IDE file type preferences XML file in the config directory. While it's possible to run such task automatically on the project refresh in IntelliJ IDEA, it will most likely not work since you can't modify IDE configuration when IDE is running (the changes will be reverted). So, you will have to run it from the command line, outside of IntelliJ IDEA when IDE is not running.
It's probably not what you want, but if documented, can be used by the team as the manual step to make this configuration change easier.
Using gradle idea is not recommended anyway.
A better way might be to provide your own IDE plug-in that will associate these file extensions with XML file type and instruct the team to install this plug-in.

How to use gradle in intellij idea plugin project?

I am developing an idea plugin, and it is an intellij idea project.
I want to use gradle to manage the dependency.
How to config?
There is now a Gradle plugin for building IntelliJ Platform Plugins. In order to use it, you will need to add the following snippet to your build.gradle file.
plugins {
id "org.jetbrains.intellij" version "0.0.31"
}
apply plugin: 'org.jetbrains.intellij'
For more information, please see this guide to help you get started.
Ok, there are multiple ways to create an IntelliJ project, "templates" if you like, and unfortunately you can only pick one of them (IntelliJ plugin or gradle).
Thankfully, it's easy to configure a project for gradle in IntelliJ.
First, create a new project from the IntelliJ Platform Plugin template. You don't need to choose any Additional Libraries and Frameworks. This will give you a project structure including META-INF/plugin.xml and the Project SDK should be something like IDEA IU-129.451.
From here, simply create a new file named build.gradle at the top level of your project, including for example this line:
apply plugin: 'java'
Now, close the project. You can now use File -> Import Project..., choose the build.gradle file that you just created, and import the project. Accept the defaults for importing and hit OK.
The project is now opened with both gradle and intellij plugin enabled!
Notice that the source root src has disappeared and you will need to right click on src in the Project pane and select Mark Directory As -> Source Root.
To prepare the plugin for deployment, there is still the menu option in the Build menu for that - if you want to automate that part via gradle, good luck and please let us know how it's done ;)

Best way to migrate an IntelliJ project to Maven?

I have a project that uses the built-in IntelliJ build system. What's the quickest/best way to migrate the project to Maven?
What's the quickest/best way to migrate the project to Maven?
Manually. Here is what I would do (I would personally use the command line):
create a parallel (potentially multi-modules) project structure using archetype(s)
declare dependencies for the jars you're using (not all of them, you'll get some transitively)
move sources and resources to the new structure
test the build
import the project back into your IDE
IDEA understands Maven very well. Unfortunately it does not create Maven configuration for you.
You'll have to write pom.xml yourself. The complexity of this depend on the structure of you project and frameworks/libraries that you use.
For me the easiest way is to create a new project based on artifact and then copy existing source files into it. You can do this in IDEA:
File -> New project -> Create project from Scratch
Choose Maven module, Next
Check Create from Artifact: a list of available artifact will show. Choose one based on libraries/frameworks you use. You can also add one if it's not on the list (search the web).
When project setup is done, start copying sources.
