android - 多个dex文件定义Landroid/support/test/espresso/contrib/DrawerActions

<分区>

当尝试迁移到 espresso 2.1 时，我遇到了以下障碍

com.android.dex.DexException: Multiple dex files define Landroid/support/test/espresso/contrib/DrawerActions$1;
    at com.android.dx.merge.DexMerger.readSortableTypes(DexMerger.java:596)
    at com.android.dx.merge.DexMerger.getSortedTypes(DexMerger.java:554)

    at com.android.dx.command.dexer.Main.main(Main.java:215)
    at com.android.dx.command.Main.main(Main.java:106)

但我只看到一个来源:

 androidTestCompile 'com.android.support.test.espresso:espresso-contrib:2.1'

关于如何解决这个问题的任何提示？这是依赖树:

最佳答案

小世界;)

此 DexException of Multiple dex files 是由 espresso-contrib:2.1 间接导致的，真正的根本原因是 com.android.support。 test:runner:0.2，它有一些其他的子依赖。

删除 test:runner 对我有用。

虽然还有一个post说是因为 com.android.support:support-v4，在你的情况下，它是 22.0.0用于测试，也许您的应用程序模块使用的是不同的版本。所以我尝试这样做:

androidTestCompile ('com.android.support.test.espresso:espresso-contrib:2.1') {
    exclude group: 'com.android.support', module: 'support-v4'
    exclude module: 'support-annotations'
}

但它根本不起作用。
