我运行以下命令（它是一个lib项目..但我也在常规项目中得到这个）：
android update lib-project -t "android-16" -p whatever_my_project_is
ant clean debug -v -d -f "${WORKSPACE}/whatever_my_project_is/build.xml"
它开始正常构建项目中的各个类，但是然后BOOM这个nullpointerexception在R.java期间发生
/Users/Shared/Jenkins/Home/jobs/Androidyaddayadda 1/workspace/whatever_my_project_is/yadda/yadda/R.java

有没有人知道在OSX上使用Ant构建Android的解决方法？我正在使用Jenkins ..但是命令通过bash为我做了同样的事情。
谢谢
