jacoco plugin: Ability to opt-out projects
Our repository includes a Tests project that contains only integration tests and no main classes. This is due to the repository originally not using the Maven standard layout. These tests are gradually being rewritten into proper unit tests, etc. as the code base is modularized. However, the Jacoco task does not work properly in this scenario without a placeholder file in main.

Another use-case is nested subprojects. For example infra:libraries:server is a library that contains the common infrastructure for a server. The infra and libraries projects are empty as they exist just for organization. Unfortunately the JaCoCo plugin fails here too.

We have a multi-language build (Java and Scala). I don't think that JoCoCo would provide appropriate test coverage. Instead I'd probably use SCCT.
My preferred solution to this would be to allow the user to specify the sub-projects to opt-in. If I only apply this plugin to the rootProject and Java projects, it fails with the error:
FAILURE: Build failed with an exception.

Sounds like a tricky build setup. Why not open up a pull request to submit your proposals? :)
