我在使用 Ant 构建包含 ActionBarSherlock 的项目时遇到问题。

实际上，编译过程中剩余的错误如下

-dex:
      [dex] Converting compiled files and external libraries into C:\ProjetsECLIPSE\SEMobile_BP\bin\classes.dex...
       [dx]

       [dx]     at com.android.dx.command.Main.main(Main.java:91)
       [dx] 1 error; aborting

我删除了我的 libs 文件夹的每个文件“android-supportv4.jar”，并且在 Eclipse 中，我确保在我的库和我的主项目中没有指向该库的链接，但错误仍然存​​在。

我可以通过 Eclipse 构建我的项目，但 Ant 无法构建它（在调试或发布模式下）。

我试过 ant clean 并没有改变任何东西。

如何避免这种令人沮丧的错误？

Check your project's libs folder and if there is duplicate jar remove it. I found actionbarsherlock.jar in my project's libs folder and after i'd deleted it, problem solved.

Also check those out; this blog, this question, and this page
