Android Studio 1.0 RC 4构建错误

Question

我尽我所能从intelij导入了一个项目，我得到了这个很长的错误，我无法理解。我试图做一个“无效并重新启动”并得到相同的错误。我不知道如果我的任何构建文件与这个错误有关，如果你有一个建议让我知道，我会更新它。

错误：执行任务'：app：dexDebug'失败。

改变构建工具来21.1.1导致此错误：

Answer 1

com.android.dex.DexException: Multiple dex files define 
com/google/analytics/tracking/android/AnalyticsClient 

该错误是由于含有谷歌分析库中的多个依赖（罐，AARS，或项目）。这可能是因为：

1. 有时中间编译文件得到一个奇怪的/糟糕的状态，特别是如果你正在调整相关性或改变你的构建工具不用清洗。转到Build-> clean项目，或运行`./gradlew clean'，然后尝试再次构建。
2. 您引用同一个库两次（例如，您包括Google Analytics jar，并且您正在使用gradle/maven工件）。删除一个或另一个。
3. 最不可能 - 两个不同的图书馆/依赖项实际上包含Google Analytics。您可以手动检查jar/aar文件，通过使用像JD-GUI这样的实用程序来查看它们包含的软件包，或者更容易地在项目的build文件夹（通常为build/intermediates）中查看Android Studio中的Android Studio，以查看是否有重复的条目对于您发布的错误中引用的包。

如果＃1不起作用，我会开始审计所有项目的依赖关系。一般来说，我远离项目结构对话框，只需手动编辑.gradle文件。我建议在您的问题中添加.gradle文件的编辑版本。
