未找到 DefaultActivityViewModelFactory

Question

将 Hilt 版本从我的项目迁移2.33-beta到2.35我的项目后，已停止构建并出现以下错误：

一个txt版本：

error: cannot access DefaultActivityViewModelFactory    
  class file for dagger.hilt.android.internal.lifecycle.DefaultActivityViewModelFactory not found   
  Consult the following stack trace for details.    
  com.sun.tools.javac.code.Symbol$CompletionFailure: class file for dagger.hilt.android.internal.lifecycle.DefaultActivityViewModelFactory not found

我的 build.gradle（项目）的一个片段：

buildscript {
    ext.hilt_version = '2.33-beta'
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:4.1.3'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.4.32"
        ...
        classpath "com.google.dagger:hilt-android-gradle-plugin:$hilt_version"
    }
}

allprojects {
    repositories {
        google()
        jcenter()
        maven { url 'https://jitpack.io' }
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

我的 build.gradle (app) 的一个片段：

}

有没有人遇到该错误并知道可能的解决方案是什么？

Answer 1

删除对 hilt-lifecycle-viewmodel 的依赖会导致错误消失，因为较新版本的 hilt 不再需要它。build.gradle如果您有此行，只需从您的应用程序级别文件中删除该行即可。

implementation 'androidx.hilt:hilt-lifecycle-viewmodel:x.x.x'

Answer 2

删除以下已弃用的依赖项：

implementation "androidx.hilt:hilt-lifecycle-viewmodel:1.0.0-alpha03"

（自 dagger-2.34 版本起已弃用）

证明： https: //github.com/google/dagger/releases/tag/dagger-2.34

另请尝试升级您的生命周期版本，如下所示：

def lifecycle_version = "2.5.1"

在build.gradle(app)的依赖部分之后添加以下行：

kapt {
  correctErrorTypes true
}

遵循官方文档：

https://developer.android.com/training/dependency-injection/hilt-android

https://dagger.dev/hilt/view-model.html

https://github.com/google/dagger/releases

Answer 3

在您的 Build.gradle (:app) 中，删除此行

implementation "androidx.hilt:hilt-lifecycle-viewmodel:1.0.0-alpha03"

你的 ViewModel 应该使用@HiltViewModel&@Inject而不是@ViewModelInject

@HiltViewModel
class MainViewModel @Inject constructor() : ViewModel() { }
