Answer 1

You can just remove the following configuration from your build.gradle file:

compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
}

The retrolambda plugin will take care of this anyway and setup the Java compiler task with the correct source and target compatibility settings.
