如何解决Android studio中的多个dex文件错误

我开始使用Android studio 1.2.0。我的项目依赖于2个库项目。所以，我将eclipse项目导入Android studio，并添加了2个库项目。 Gradle构建成功。当我试着运行它的时候，我的错误率就降低了

    * What went wrong:
Execution failed for task ':dexDebug'.
> com.android.ide.common.internal.LoggedErrorException: Failed to run command:
    F:\AndroidStudioSetup\build-tools\22.0.1\dx.bat --dex --no-optimize --output F:\3.0 Studio Migrartion\SdkSample\platforms\android\build\intermediates\dex\debug --input-list=F:\3.0 Studio Migrartion\SdkSample\platforms\android\build\intermediates\tmp\dex\debug\inputList.txt
Error Code:
    2
Output:

请帮我找出我添加了两次的库，提前谢谢

android{
  multiDexEnabled true
}

---

在build.gradle中添加此多个dex文件定义…通常在

build.gradle中复制库时发生。我的猜测是问题的出现是因为在build.gradle文件中都定义了
com.android.tools.build:gradle:1.0.0+
。
