Question

在将Android Studio更新到3.0.1之前，我从未遇到过dex merge错误。在我更新到3.0.1后，我开始面临以下错误

Error:Execution failed for task ':app:transformDexArchiveWithExternalLibsDexMergerForDebug'.
> com.android.builder.dexing.DexArchiveMergerException: Unable to merge dex

为了解决这个问题，我在stackoverflow和google中尝试了很多解决方案，但我没有得到任何解决方法。

例如：

我尝试添加defaultConfig multiDexEnabled true并更新了Myapplication.java文件。

我试图清理并重建。

我尝试Invalidate catch / Restart然后重建。

构建应用程序时出现以下错误：
