## Stack Trace（` ./gradlew spotlessApply --stacktrace > out 2>&1 `）
https://gist.github.com/polyomino24/4cbc3f0900a4dc85577151b70ad97cb8

Riproduci il fallimento con la classe Groovy di esempio eseguendo ./gradlew spotlessGroovy con la configurazione greclipse mostrata, quindi ispeziona il percorso del formatter indicato dallo stack trace. Il lavoro è completato quando il comando accetta e formatta una closure Groovy scritta come () -> {} senza generare l’unexpected-token error.
