我已将一个功能从app模块中分离到一个动态功能模块（名为dfm）中。

该模块在我遵循所有最佳实践和要求的情况下完美运行。但是 androidTest 中使用 Espresso 的测试用例之一在AndroidJUnit4构建任务时不起作用并且失败并中断：mergeLibDexDebugAndroidTest。该项目包括：

  • app模块：主模块
  • testlib：库模块包含几个用于单元测试的类（不被不运行的 espresso 测试用例使用）
  • dfm: espresso 测试用例所在的 动态功能模块
    没有具体错误，但它只是给出以下错误消息：
2020-07-15 20:40:42.705:INFO:oejs.ServerConnector:Daemon worker Thread 34: Stopped ServerConnector@eda0043{HTTP/1.1}{localhost:0}

我无法获取特定错误并了解它是否是 Gradle 文件或我的代码中的问题，因为任何地方都没有编译错误。请帮助我理解错误。谢谢

在错误日志中，我们看到以下行：

Failed to transform classes.jar (project :testlib) to match attributes {artifactType=android-dex, com.android.build.api.attributes.BuildTypeAttr=debug, com.android.build.api.attributes.VariantAttr=debug, dexing-enable-desugaring=true, dexing-incremental-desugaring-v2=false, dexing-is-debuggable=true, dexing-min-sdk=21, org.gradle.libraryelements=jar, org.gradle.usage=java-runtime, org.jetbrains.kotlin.platform.type=androidJvm}.

testlib因此，在研究了上述消息并暗示它dfm/build.gradle与androidTestImplementation project(":testlib"). 由于目前没有对androidTestsfrom 的依赖testlib，这是不必要的，因此失败了。androidTestImplementation project(":testlib")因此，我删除了使测试构建成功的不必要的东西。
