Description

Once in a while our Gradle build fails with following error (aprox. every 4th build):

What went wrong:
Could not resolve all dependencies for configuration ':shared:compile'.
Cause: org.gradle.api.internal.artifacts.dependencies.DefaultProjectDependency_Decorated cannot be cast to org.gradle.api.artifacts.ExternalModuleDependency

Its after upgrading to milestone-6. It happens both on my Windows work machine and on out Jenkins build server.

I've also been running into this on both Windows and Linux. For me it happens on the compileJava task of the first module to declare a project level dependency compile project(:raa-shared). Here is a snippet of a failed build:

[23:31:25]: :clean

[23:31:27]: :raa-shared:jar
[23:31:27]: :raa-client-shared:compileJava
[23:31:27]: FAILURE: Build failed with an exception.
[23:31:27]: * What went wrong:

Comment by Anders Viskum [ 02/Jan/12 ]

Could someone help with this issue? We are considering using another build tool because of this bug

Comment by Lari Hotari [ 02/Jan/12 ]

This bug affects also the grails build (master branch). The problem doesn't show up every time.

Comment by Adam Murdoch [ 02/Jan/12 ]

@anders, we're looking in to it. You might try running your build with java 6 as a work around.

Comment by Anders Viskum [ 03/Jan/12 ]

thx Adam - let me know if you need any help, e.g. my build file

Comment by Adam Murdoch [ 06/Jan/12 ]

This should be fixed now. Can you try the snapshot build from http://gradle.org/nightly ?

Comment by Anders Viskum [ 06/Jan/12 ]

It is fixed on gradle-1.0-milestone-8-20120106071535+0100. Thank you
