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

Question

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?

Solution 1

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).

Solution 2

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'.

Solution 3

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.

But what if we need to set custom value? What if the directory is used also with another tool doing another phase? At this time, with Eclipse we don't have a problem, but with IDEA we do.

@dmatej It is possible to set the location for generated sources. See 'Generated sources folders' option at jetbrains.com/idea/webhelp/maven-importing.html

Be sure to use mvn idea:idea to ensure that this takes place after adding the mvn plugin module to your pom.

mvn idea:idea solved the issue in my case. Thank you.
