Unable to query the project's dependencies via Gradle

[sschuberth]

This is an issue with the project's build system (and Scala plugin), not with the project itself. For checking a Gradle project's dependencies I usually execute the dependencies task, but that fails for this project:

$ ./gradlew scanns:dependencies
Parallel execution with configuration on demand is an incubating feature.
Build cache is an incubating feature.
Using local directory build cache for build ':buildSrc' (location = C:\Users\seschube\.gradle\caches\build-cache-1).

FAILURE: Build failed with an exception.

* What went wrong:
Project 'scanns' is ambiguous in root project 'scanns'. Candidates are: 'scanns_2.10', 'scanns_2.11'.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

Thanks for pointing this out. This is happening because of the cross-building support added to the module to allow users to build it against their desired scala versions.

In case you haven't unblocked yourself yet, ./gradlew :scanns_2.10:dependencies or ./gradlew :scanns_2.11:dependencies will work. They will both yield the same result except all their respective dependencies will be built against the particular scala version. IMO, this is the correct behavior: the dependencies can't be pin-pointed unless you specify the scala version you are building against but I'll see if I can assign a default behavior so that ./gradlew :scanns:dependencies also succeeds, assuming a particular version of scala.

Thanks for the explanation. BTW, is there a separate repository where the Scala Cross Build Gradle plugin is maintained? So far I only saw its source code being committed as buildSrc to multiple projects, but if you did the fix to make ./gradlew :scanns:dependencies work, that fix would probably happen in the plugin, and it would make sense that other projects would get this fix, too.
