error to run  
./gradlew clean build

and the lines are blank, there is no code. Then why the error?

This sounds as if the lines are not fully emtpy. Can you check if they maybe **only** contain a tab but nothing else (this way they would look empty, but are not).

You can enable/disable the forbidden patterns task in your gradle build, if you need to as well (even though I'd recommend to keep it enabled).
