I have an Android App in Android Studio. When I build project with Gradle File,it gives me one error at compile time. Error Report:

Error:org.gradle.api.internal.changedetection.state.DefaultFileCollectionSnapshotter$FileCollectionSnapshotImpl cannot be cast to
org.gradle.api.internal.changedetection.state.OutputFilesCollectionSnapshotter$OutputFilesSnapshot

解决方案：

1.delete {project dir}/.gradle/1.9

2.Sync Project with Gradle File

把项目中的.gradle文件夹删除，然后同步即可。
