java - 在 IntelliJ 中找不到符号变量 DaggerAppComponent

Question

我克隆了这个项目https://github.com/robohorse/RoboPOJOGenerator并尝试在 IntelliJ IDE 的帮助下进行构建。

它已成功导入并下载了必要的依赖项，但当我重建它时它失败了。

Error:(10, 24) java: cannot find symbol
  symbol:   variable DaggerAppComponent
  location: class com.robohorse.robopojogenerator.injections.Injector

我已经尝试了许多 stackoverflow 线程，但对我不起作用。这是 gradle 还是 dagger 的东西。

**@Singleton**
@Component(modules = AppModule.class)
public interface AppComponent {
...
}

确保为您的组件添加了 @Singleton 注释。
