java - Dagger 在 Android 应用程序中生成重复的 `XXXDialogFragment_MembersInjector` 类(程序类型已存在)

标签 java android kotlin dependency-injection dagger-2

我有一个 BaseDialogFragment，它使用 Dagger 的依赖注入(inject)，然后我有两个不同的模块，它们是 BaseDialogFragment 的子类。

尝试构建时出现以下错误:

> Task :app:transformClassesWithDexBuilderForDevelopmentDebug
AGPBI: {"kind":"error","text":"Program type already present: BaseDialogFragment_MembersInjector","sources":[{}],"tool":"D8"}

> Task :app:transformDexArchiveWithDexMergerForDevelopmentDebug FAILED
java.lang.RuntimeException: java.lang.RuntimeException: com.android.builder.dexing.DexArchiveMergerException: Error while merging dex archives:

我搜索了我的项目，似乎只生成了两个不同的 BaseDialogFragment_MembersInjector 类:每个模块中都有一个。

我已经:

  1. 清理项目
  2. 删除了生成的重复类
  3. 使缓存无效并重新启动
  4. 更新了 Dagger 版本
  5. 确保 multidexEnabled 设置为 true
  6. 根据发现的建议在基类上添加了不必要的@inject 字段here

我也看过这个问题here — 不确定是否相关，但听起来很相似。

谁能告诉我这是怎么回事？感谢您的帮助。

最佳答案

您的 BaseDialogFragment_MembersInjector 实际上为每个子模块生成了多次，如前所述。在组装最顶层的 :app 模块时发生了碰撞。清理或删除 build/ 目录并重新创建它们实际上无济于事。

你应该做的是扩展你的 BaseDialogFragment，比如说，在 :base 模块(靠近 BaseDialogFragment )。

  • 然后您必须向它添加一些虚拟的@Inject-annotated 字段(以强制 Dagger 在 :base_MembersInjector > 而不是在子模块中)。

  • 然后从 SimpleBaseDialogFragment 扩展任何进一步的对话框 fragment ，然后清除并重建项目。

例如(在 Kotlin 中):

class DummyInjectableField @Inject constructor() {}

class SimpleBaseDialogFragment : BaseDialogFragment() {

    @Inject lateinit var dummy: DummyInjectableField
}

这只是一种解决方法，对我的情况有所帮助。 请在此处查看解释:https://github.com/google/dagger/issues/955
