当我尝试与uiAutomation一起运行我的android测试时，我无法合并dex异常。
androidTestImplementation ('com.google.android:android-test:4.1.1.4')
错误：任务＆＃39;：app：transformDexArchiveWithExternalLibsDexMergerForDebugAndroidTest＆＃39;执行失败。 java.lang.RuntimeException：java.lang.RuntimeException：com.android.builder.dexing.DexArchiveMergerException：无法合并dex
但是，如果我从androidTestImplementation更改为testCompile，一切正常。如果有人能解释androidTestImplementation和testCompile之间的不同行为，我会很高兴。其次，我如何使用androidTestImplementation添加这个依赖。

根本原因是XmlPullParserException类的冲突。该类是xxp3依赖项的一部分，是org.simpleframework.simplexml的一部分。

要解决此问题，我必须从com.google.android:android-test中排除dependecy。
