Android AssertJ 1.0.0 with Android gradle 1.1.1

Question

Here is part of my build.gradle that has conflict:

...
dependencies {
  classpath 'com.android.tools.build:gradle:1.1.1'
}
...
testCompile( 'com.squareup.assertj:assertj-android:1.0.0' )
...

The issue that I see in log:

WARNING: Conflict with dependency 'com.android.support:support-annotations'. Resolved versions for app (21.0.3) and test app (20.0.0) differ.

Apparently it removes conflicting dependency from the classpath. I'm not sure if it is gradle or android gradle plugin.

I've tried next:

  testCompile( 'com.squareup.assertj:assertj-android:1.0.0' ) {
    exclude group: 'com.android.support', module: 'support-annotations'
  }

But I still have compilation errors so dependency is excluded.

I've tried next:

configurations.all {
  resolutionStrategy {
    // fail eagerly on version conflict (includes transitive dependencies)
    // e.g. multiple different versions of the same dependency (group and name are equal)
    failOnVersionConflict()

    // force certain versions of dependencies (including transitive)
    //  *append new forced modules:
    force 'com.android.support:support-annotations:21.0.3'
    //  *replace existing forced modules with new ones:
    forcedModules = ['com.android.support:support-annotations:21.0.3']
  }
}

But looks like it doesn't work since it is not failing on the first conflict and I still have compilation errors.

What will be your suggestions?

UPDATE What do I mean by removing dependency - I see a lot of compile errors that assertj not found

I ran into the same issue. This fixed it for me:

testCompile('com.squareup.assertj:assertj-android:1.0.0'){
    exclude group: 'com.android.support', module:'support-annotations'
}
