我使用 android update project 更新了项目，当我命令“ant clean”时构建成功，但是当我向前执行命令“ant release”时，显示了上述失败消息。我正在使用 apache-ant-1.8.2

【参考方案1】：

问题出在这里：

-dex:

  [dex] Converting compiled files and external libraries into C:\Users\smanandhar\workspace\Obfuscation\bin\classes.dex...
   [dx] unknown option: --output

构建文件的dex 目标调用带有无效参数的dx 命令。

这会将您带到this SO question，它会提供解决方案的方向
