Crashlytics多个dex文件定义错误

我使用intellij 14.0.3.
通过使用"从磁盘安装插件"我安装了Crashlytics intellij插件.
当我尝试在我的代码中导入Crashlytics并构建时出现以下错误.

Error:Android Dex: [myapplication] Unable to execute DX

我卸载了插件并重新安装,但我仍然遇到这个问题.
插件在项目的lib文件夹中创建一个crashlytics.jar文件.
当我删除该文件时,插件会自动创建一个新文件.

我怎样才能找到有问题的问题？目前我包括这些库:
- Google Play服务
- Google分析
- Android支持lib
- Loopj async http lib
- Commons lang lib

更新到结构时发生了这种情况.我不得不从libs文件夹中删除crashlytics.jar.
