Other solutions here have not helped me yet. I am seeing builds lasting 30+ minutes only to end with Error:Out of memory: GC overhead limit exceeded. But I have made slight progress the past few days.

Note: I do not believe this is a solution to the problem, just a workaround until Jack works out the kinks

I added the following to my build gradle:

android {
    ....
  defaultConfig {
    ....
    jackOptions {
            enabled true
            additionalParameters('jack.incremental': 'true')
        }
    }

    compileOptions {
        incremental true
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

    dexOptions {
        javaMaxHeapSize '4096m'
    }

}

For some reason, adding

org.gradle.jvmargs=-Xmx4g -XX:MaxPermSize=512m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8 

to my gradle.properties made no difference. I had to add it in the dexOptions.
