NoClassDefFoundError: Failed resolution of: Landroidx/tracing/Trace

Question

当我启动基本的 androidTest 时，我的应用程序崩溃了：

@Test
fun myTest() {
    val scenario = ActivityScenario.launch(MainActivity::class.java)
    // ...
}

这是堆栈跟踪：

以下依赖项导致了问题：

androidTestImplementation 'androidx.lifecycle:lifecycle-extensions:2.2.0'
androidTestImplementation 'androidx.lifecycle:lifecycle-process:2.4.0'
androidTestImplementation 'androidx.lifecycle:lifecycle-runtime-ktx:2.3.1'
