There can be many causes of this issue but having something like this in the build script can reproduce the issue:

sourceSets.main.runtimeClasspath -= configurations.provided

This particular case can be worked around by adding the following code after the previous one:

sourceSets.main.runtimeClasspath += files()

Anyway, it is fixed in master and the fix will be included in 1.2.9.

[shevek]

project.sourceSets {
    main.compileClasspath += project.configurations.provided
    main.runtimeClasspath -= project.configurations.provided
    test.compileClasspath += project.configurations.provided
    test.runtimeClasspath += project.configurations.provided
}

For the record, the project uses the stock netflix-gradle-template; that may be worth using as a test case.

I have added a simplier test case which tests this issue (ensuring no regression). By the way, you can try to build the plugin from the sources. The only thing about the current state is that it reports exception stack traces in an awkwardly small text area. On the other hand the new API, can now distinguish between issues (build script issue, dependency resolution failures and bugs in the plugin itself).

[shevek]

I meant, whatever the status of this bug, the netflix gradle template should be a test case, as it is commonly used, and may throw up other bugs.
