I have a project that has inexplicably started failing during compilation. The failure is intermittent.
This is running under Linux using gradle 1.0 milestone 7.
:proj3:compileJava
FAILURE: Build failed with an exception.
* What went wrong:
Could not resolve all dependencies for configuration ':proj3:compile'.
Cause: org.gradle.api.internal.artifacts.dependencies.DefaultProjectDependency_Decorated cannot be cast to org.gradle.api.artifacts.ExternalModuleDependency
* Try:
Run with --debug option to get more log output.
* Exception is:
org.gradle.api.artifacts.ResolveException: Could not resolve all dependencies for configuration ':proj3:compile'.
