java.lang.RuntimeException：缺少从@HiltAndroidTest生成的Hilt类

我正在尝试使用 Hilt 运行一个简单的 Robolectric 测试。

@HiltAndroidTest
@Config(application = HiltTestApplication::class)
@RunWith(AndroidJUnit4::class)
class SplashActivityTest2 {

    @get:Rule
    var hiltRule = HiltAndroidRule(this)

    @Test
    fun fooTest() {
        val splashActivity = ActivityScenario.launch(SplashActivity::class.java)
    }
}

但是当我尝试使用 Android Studio 运行测试时，我得到了

java.lang.RuntimeException：缺少从 @HiltAndroidTest 生成的 Hilt 类。检查您是否已使用 @HiltAndroidTest 注释您的测试类，并且处理器正在运行您的测试

这是完整的堆栈跟踪。

[Robolectric] com.theapache64.nemo.feature.splash.SplashActivityTest2.fooTest: sdk=28; resources=BINARY
Called loadFromPath(/system/framework/framework-res.apk, true); mode=binary sdk=28

java.lang.RuntimeException: Hilt classes generated from @HiltAndroidTest are missing. Check that you have annotated your test class with @HiltAndroidTest and that the processor is running over your test

这是我的app/build.gradle

与纯 instrumentationTest 相同的文件(androidTest)虽然有效。
