我正在尝试将 Hilt 集成到我的项目中，但我无法通过初始配置。到目前为止，我按照官方文档一步一步添加了插件和依赖项。一旦我用 标记Application类@HiltAndroidApp，构建就会失败并出现以下错误：

/.../app/build/generated/source/kapt/stagingDebug/..../DaggerMyApp_HiltComponents_ApplicationC.java:110: error: cannot find symbol
        return ImmutableSet.<ViewModelProvider.Factory>of();}
                           ^
  symbol:   method <Factory>of()
  location: class ImmutableSet
/.../app/build/generated/source/kapt/stagingDebug/..../DaggerMyApp_HiltComponents_ApplicationC.java:143: error: cannot find symbol
          return ImmutableSet.<ViewModelProvider.Factory>of();}
                             ^
  symbol:   method <Factory>of()
  location: class ImmutableSet
2 errors

我检查了生成的文件，发现了一些麻烦的方法：

@Override
      public Set<ViewModelProvider.Factory> getActivityViewModelFactory() {
        return ImmutableSet.<ViewModelProvider.Factory>of();}

@Override
        public Set<ViewModelProvider.Factory> getFragmentViewModelFactory() {
          return ImmutableSet.<ViewModelProvider.Factory>of();}

我对 Dagger 和 Hilt 还很陌生，所以我不知道这可能来自哪里。我认为这可能是一个依赖问题，但我没有得到任何运气。我在项目中导入了一些外部模块，这是我的 gradle：

ImmutableSet来自 Guava，但您的依赖项中不包含 Guava。

为此，请添加到您的依赖项：

implementation 'com.google.guava:guava:29.0-android'

如果 Hilt 将代码生成对 的引用ImmutableSet，我的期望是com.google.dagger:hilt-android:xx它将 Guava 作为传递依赖项包括在内。要确认/否认该假设，并更好地理解为什么它可能不包括在内，请运行./gradlew :app:dependnecies. 并寻找任何使用guava.
