Gradle: common resource dependency for multiple java projects

Question

I'm developing a multi-module project with gradle/intellij-idea, and here is the structure of my project home:

project/   sub-project-1     /main/resources   sub-project-2     /main/resources   data     /main/resources     /test/resources 

As you can see I have multiple sub-projects (all java), how can I make them depend on some common resources (the "data" project, which contains no code but only resources), as well as their own separate resources?

Also it's best that the intellij-idea can pick up these dependencies with JetGradle automatically (JetGradle do just fine picking up the default gradle java project dependencies within each sub project).

Thanks a lot!

Answer 1

The approach I took was to use project reference

sourceSets {     main {         resources {             srcDirs += [                 project(':data').sourceSets.main.resources             ]         }     } } 

UPDATE: Tested with Gradle7 and it still works. Tested with java-library plugin.

Answer 2

One solution is to apply the Java plugin also to the data project, and then use regular project dependencies (e.g. dependencies { runtime project(":data") }). However, this would require a bit of effort to prevent shipping the test resources.

Another solution is not to make data a Gradle project but literally include its resource directories in the other two projects (sourceSets.main.resources.srcDir "../data/main/resources"; sourceSets.test.resources.srcDir "../data/test/resources").
