android - dexDebugTest失败，并带有DexException “Cannot merge new index”进行测试

Question

我正在使用gradle构建一个利用Google Espresso的android项目(这要归功于Jake Wharton的双重意式浓缩咖啡)。通过我的build.gradle配置，我可以使用proguard成功地构建调试和发行版本，以优化我的方法数量(以达到65k的限制以下)，但是当我运行connectedAndroidTest时，我的构建失败了:

:src:MyAppLibrary:dexDebugTest FAILED

我的应用程序称为MyApp，它具有一个名为MyAppLibrary的依赖项项目。在切换到espresso之前，运行connectedAndroidTest时没有达到65k的限制。我以前使用过robotium，并且此后已经删除了那些依赖项。另外，当我只构建调试或发布构建时，我没有达到极限。有没有像优化调试版本那样优化我的测试版本的方法？

对我来说奇怪的是，我仅在MyApp中有测试，而MyAppLibrary中没有任何测试类。实际上，当我运行connectedAndroidTest时，实际上可以看到我的测试在设备上运行并通过MyAppLibrary:dexDebugTest。那么，为什么在运行我的测试后为什么它在那里失败呢？

或者，是否可以以某种方式绕过MyAppLibrary的connectedAndroidTest依赖关系链调用？

谢谢!

在build.gradle中，您需要指定:

android {
   dexOptions {
      jumboMode true
   }
}
