[java] Android 스튜디오-android-18 대상을 찾지 못했습니다.

RobertoAV96 감사합니다.

당신은 나의 영웅이다. 하지만 충분하지 않습니다. 제 경우에는 compileSdkVersion과 buildToolsVersion을 모두 변경했습니다. 이제 작동합니다. 이 도움을 바랍니다

           // For instance, build-types/debug/java, build-types/debug/AndroidManifest.xml, ..
           // This moves them out of them default location under src/<type>/... which would
           // conflict with src/ being used by the main source set.
           // Adding new build types or product flavors should be accompanied
           // by a similar customization.
           debug.setRoot('build-types/debug')
