我的视图模型类的导入语句有一些问题。如果我在导致错误的两个viewmodel及其依赖项中清除或添加一行，我就可以再成功构建一次。但给我"未解决的参考"上一堆我注入的视图模型，如果我改变我的活动/片段的任何东西，并尝试再次构建没有清洗。
我已经在gradle文件中尝试了所有不同类型的配置，但无济于事。我尝试了不同的android studio版本，不同的Hilt版本，Kotlin版本。使缓存无效，重新启动和其他一切。谁来帮帮我吧!
我已经尝试粘贴我的配置下面，连同我的MainActivity导入语句和未解析引用引用的视图模型之一。

嗨，你的手柄版本可能是错误的，我有类似的问题，下面的设置对我来说是有效的，把它改成2.34测试版，你能在构建gradle应用程序
//Dagger - Hilt
implementation "com.google.dagger:hilt-android:2.34-beta"
kapt "com.google.dagger:hilt-android-compiler:2.34-beta"
//extra dagger hilt dependecies for view model lifecycle attaching for your reference
implementation "androidx.hilt:hilt-lifecycle-viewmodel:1.0.0-alpha03"
kapt "androidx.hilt:hilt-compiler:1.0.0"
implementation 'androidx.hilt:hilt-navigation-compose:1.0.0-alpha03'
并将最小SDK版本更改为
minSdk 24
我的kotlin gradle插件是1.5.10在项目级别(如果它有帮助)
问题存在于从Hilt和我的Apollo模式文件生成的文件中。我在我的android项目中有一个名为user的包，在我的Apollo模式目录中有一个名为User的子文件夹，这显然使android studio在随后的构建中感到困惑。解决方案是删除Apollo模式目录中的子文件夹，或者将项目中的包命名为与模式目录中的子文件夹不同的名称。
对于我来说，我刚刚添加了视图模型生命周期依赖关系，如下所示:
implementation "androidx.hilt:hilt-lifecycle-viewmodel:1.0.0-alpha03"
kapt "androidx.hilt:hilt-compiler:1.0.0"
