运行检测测试时 Cloud Firestore (22.1.0) 出现内部错误

Question

我收到来自 Cloud Firestore 的内部错误消息。当我运行此测试时，该应用程序正在从 Firebase 获取项目列表。这需要一段时间。与此同时，测试停止。

每个库都更新到最新版本。这个SO thread 没有给出令人满意的答案。错误只在运行测试时出现，实际App没问题。

@InternalCoroutinesApi
@ExperimentalCoroutinesApi
@RunWith(AndroidJUnit4::class)
class HomeTest {

    @get:Rule
    var reportHelper: ReportHelper? = Factory.getReportHelper()

    @get:Rule
    var activityRule = ActivityScenarioRule(MainActivity::class.java)

    // Executes tasks in a synchronous [TaskScheduler]
    @get:Rule
    var syncTaskExecutorRule = SyncTaskExecutorRule()

    @Before
    fun goToHomeScreen() {
        onView(withId(R.id.navigation_home)).perform(ViewActions.click())
    }

    @Test
    fun scrollToNextVideo() {
        onView(withId(R.id.recycler)).perform(swipeUp())
    }

    @After
    fun TearDown() {
        reportHelper?.label("Stopping App")
    }
}

build.gradle（应用级）：

android {
    configurations.all() { configuration ->
//    exclude group: "com.google.protobuf", module: "protobuf-javalite"

       exclude group: "com.google.protobuf", module: "protobuf-java"
//    exclude group: "io.grpc", module: "grpc-protobuf-lite" // tried this, but App fails to compile
}
dependencies {
    implementation "com.google.firebase:firebase-firestore-ktx:23.0.0"
    implementation "com.google.firebase:firebase-database-ktx:20.0.0"
    implementation "com.google.firebase:firebase-storage-ktx:20.0.0"
    implementation "com.firebaseui:firebase-ui-storage:4.3.2"
}

这是我的dependencies.txt

tried this，不起作用。 this also 没用。

TL;DR：protobuf-javalite 是您可能想要构建的对象。

这是一个known issue，很可能是由您隐瞒的build.gradle 的一部分引起的。我只能说，排除模块protobuf-javalite 会去掉静态方法registerDefaultInstance；因此应该只排除protobuf-java：

configurations.all() { configuration ->
    // exclude group: "com.google.protobuf", module: "protobuf-javalite"
    exclude group: "com.google.protobuf", module: "protobuf-java"
}

使用 Kotlin 依赖项也可能有意义，但这不应该是原因：

implementation 'com.google.firebase:firebase-firestore-ktx:22.1.2'

要检查实际打包的内容：./gradlew :app:dependencies > dependencies.txt。
