使用Gradle3.0的時候報錯：

 Gradle sync failed: Cause: org.gradle.api.internal.tasks.DefaultTaskInputs$TaskInputUnionFileCollection cannot be cast to org.gradle.api.internal.file.collections.DefaultConfigurableFileCollection

         Consult IDE log for more details (Help | Show Log)Failed to sync Gradle project 'mi-cashier-android'Error:Cause: org.gradle.api.internal.tasks.DefaultTaskInputs$TaskInputUnionFileCollection cannot be cast to org.gradle.api.internal.file.collections.DefaultConfigurableFileCollectionPossible causes for this unexpected error include:<ul><li>Gradle's dependency cache may be corrupt (this sometimes occurs after a network connection timeout.)<a href="syncProject">Re-download dependencies and sync project (requires network)</a></li><li>The state of a Gradle build process (daemon) may be corrupt. Stopping all Gradle daemons may solve this problem.

具體的問題沒有調查清楚，

解決的辦法

可以暫時的將Gradle降為2.14.1 就可以了

如何修改這裡的Gradle包，請參考：
