Jack and Jill and destinationDir

Question

Google has officially released Jack & Jill as mentioned on their blog .

But if I use the following property :

defaultConfig {
    applicationId 'xxx'
    minSdkVersion 10
    targetSdkVersion 19
    versionCode 162
    versionName 'xxx'
    // Enabling multidex support.
    multiDexEnabled true
    testInstrumentationRunner "android.support.multidex.MultiDexTestRunner"
    manifestPlaceholders = [ cappId:"xxx",cappLog:"false" ]
    useJack = true
}

I get the following error

Error:Cannot get property 'destinationDir' on null object

I have no problem if I comment use Jack property

I know it's an experimental tool but do you know how can I fix that ?

Answer 1

Are you using retro-lambda, dagger2 or any other annotation processing library? In that case you need to manually specify the processor.

See this thread: https://github.com/evant/gradle-retrolambda/issues/71
