更新gradle版本3.0后，JacocoTestReport无法正常工作

Question

我在Android项目中开始从Gradle 2.3迁移到Gradle 3.0。我解决了这个迁移过程中的大多数问题，但我仍然有一个我无法解决它的问题。问题在于jacocoTestReport任务，我不知道为什么会出现此错误。我尝试将jacoco插件更新到最新的avaiable版本但没有成功。下面我打了原始的jacoco gradle文件。任何提示？

  

出了什么问题：任务执行失败＆＃39;：mobile：jacocoTestReport＆＃39;。   无法读取执行数据文件/ Users / mbratkowski / android_projects / android_app / mobile / build / jacoco / testQaGoogleDebugUnitTest.exec```
