Annotation processor error "Could not execute transformation"

[kiwiandroiddev]

I'm seeing:

What went wrong:
Execution failed for task ':appname:transformLogLifeCycleProcessorAbcDebug'.
> Could not execute transformation

This is with the following top-level build.gradle:

// ..
    dependencies {
        classpath 'com.android.tools.build:gradle:1.2.2'
        classpath 'com.github.stephanenicolas.loglifecycle:loglifecycle-plugin:1.0.3'
    }

And apply plugin: 'loglifecycle' added to the app module's build.gradle. Can provide more environment info if needed.

Same error here. @kiwiandroiddev do you have things like Dagger or ButterKnife which use annotations?

[kiwiandroiddev]

@mlatu yes we're using butterknife. Is there some sort of conflict?
