我正在关注这个例子Code Coverage for Android，我能够使蚂蚁运行构建，但它给我带来了这个错误。
BUILD FAILED
/home/user/Documents/android-sdk-linux/tools/ant/build.xml:620: The following error occurred while executing this line:
/home/user/Documents/android-sdk-linux/tools/ant/build.xml:601: Invalid file: /home/user/android-workspace/appcompat_v7/build.xml
而且我不知道该怎么做。感谢
