:app:mergeDebugResources エラー　android 　解決方法がわかりません。

Android Studioで
Error:Execution failed for task ':app:mergeDebugResources'.

Some file crunching failed, see logs for details

というエラーが出てしまいました。
解決方法を教えていただけないでしょうか？

ビルトログは、
0:48:35 Executing tasks: [:app:clean, :app:generateDebugSources, :app:mockableAndroidJar, :app:prepareDebugUnitTestDependencies, :app:generateDebugAndroidTestSources, :app:assembleDebug]

です。

画像は抜けない状態です。
急いでいます。

よろしくお願いします。

Gradle Consoleです。
