Issues with compilation against an Android-Scala Project

Has anyone else had issues compiling an Android project written in Scala with CircleCI? I can’t seem to get my build compiling, and all sorts of compilation errors get thrown - mostly related to specific Java classes and whatnot. Any thoughts or common gotchas?

Stack Trace from Container:

My Circle.YML file its as so:

#general:

artifacts:

- /home/ubuntu/earbits_android/app/build/outputs/apk/

machine:
environment:
ANDROID_HOME: /usr/local/android-sdk-linux

test:
override:
- ./gradlew assemble --stacktrace --continue

dependencies:

- echo y | android update sdk --no-ui --all --filter tools,platform-tools,build-tools-22.0.1,android-23,extra-google-m2repository,extra-google-google_play_services,extra-android-support
- ANDROID_HOME=/usr/local/android-sdk-linux ./gradlew dependencies

Is this project open source? If so, could you paste the build URL? If not, that’s ok too. I don’t have much experience with Scala + Android but maybe we can find a simple open source project to poke around in.

Out of curiosity does the Building step ever finish?
