Example project for reproducing an IntelliJ(?) Bug

Rough structure:

    :deployments:swing
       /          \
:modules:javase  :modules:businesslogic
       \          /
      :modules:base

base includes the API, which businesslogic implements. javase has a main method that wants to have an implementation of API, which it is decoupled from. deployments includes both together (as runtime dependencies) to provide a runnable package, which is glued together by Weld (CDI).

How to reproduce:

Step 1: Open this project in IntelliJ IDEA (should be imported as a gradle project), runtime is openjdk 11

Step 2: Set up a Run configuration as follows:

Step 3: Run the configuration

Expected Result:

Everything of the following:

1. running it succeeds without an error
2. the classpath output includes the businesslogic module
3. it outputs (among other lines):

This is important: This is the result

Actual Result:

5:15:49 PM: Executing ':modules:javase:Main.main()'...

Hints

1. This does work when using a gradle configuration or running ./gradlew :deployments:swing:run on the command line.
2. The printed classpath does not include the businesslogic module
3. IntelliJ seems to try to execute :modules:javase:Main.main() (see logs above) even though I explicitly intended to run :deployments:swing.
