Android ：app:jillDebugPackagedLibraries失败

我使用的是Android Studio 2.1.2，可以使用标准工具链进行良好构建，但是启用jack时：

jackOptions {
            enabled true
        }

我得到：

    * What went wrong:
    Execution failed for task ':app:jillDebugPackagedLibraries'.
    > com.android.jill.JillException

    * Try:
    Run with --info or --debug option to get more log output.

Caused by: java.lang.NullPointerException
