Run task fails when opening resource-only package

[mkroening]

I need to open up a resource package not containing any classes, but the run task fails.
Running the build task and then executing the distribution will work.

A workaround is creating a dummy class in the package.

I stumbled onto this bug while experimenting with OptaPlanner on the module path: mkroening/optaplanner-modulepath-example#2

I also modified the test-project to show this behaviour: mkroening@48c5793
Running $ ../gradlew :greeter.runner:run will fail, but $ ../gradlew :greeter.runner:build and then executing the distribution succeeds.

I have the same problem, gradle run fail ("Package test.main.asset not found in module"), but gradle installDist generate a working application.

If it can help, I made a minimal test project for this issue:

Edit: Ok, I forgot about that, but there is already an issue about this topic on the gradle github:
gradle/gradle#4733

I've seen this too. I'm not sure if this is an issue with this plugin or something else. Happy to accept a PR to fix this issue.
