我的Android项目使用了几个标记为Android库的git子模块.这些子模块都具有ORMlite Android jar的不同用途,因此其libs目录中包含ORMlite jar .Eclipse正确处理这种情况:它在dex处理过程中包含一次ORMlite jar 并生成一个有效的.apk,但是当我运行build via时ant debug,我得到:

 [echo] Converting compiled files and external libraries into /home/webedit/.hudson/jobs/xyz/workspace/bin/classes.dex...

有没有办法让多个库中有相同JAR的多个副本？是否有一个Ant构建设置我可以更改以使其工作？
