[已解决]Gradle 3.0 出现问题

使用Gradle3.0的时候报错：

 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.DefaultConfigurableFileCollection
Possible 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.

<a href="stopGradleDaemons">Stop Gradle build processes (requires restart)</a></li><li>Your project may be using a third-party plugin which is not compatible with the other plugins in the project or the version of Gradle requested by the project.</li></ul>In the case of corrupt Gradle processes, you can also try closing the IDE and then killing all Java processes.

具体的问题没有调查清楚，

解决的办法

可以暂时的将Gradle降为2.14.1 就可以了

如何修改这里的Gradle包，请参考：

2.7-3 Android Studio 的Gradle一点理解, 查看gradle 版本和android 插件的版本
