Android Dagger 2为组件抛出错误。Builder:@Component.Builder缺少所需模块或组件的设置程序：

我有一个组件

AppComponent

@Component
public interface AppComponent {

}

@Component(dependencies = {OtherComponent.class})
public interface AppComponent {

    @Component.Builder
    interface Builder {
        @BindsInstance
        Builder setContext(Context context);

        AppComponent build();
    }
}

@Component(dependencies = {OtherComponent.class})
public interface AppComponent {

    @Component.Builder
    interface Builder {
        @BindsInstance
        Builder setContext(Context context);

        Builder setOtherComponent(OtherComponent otherComponent);

        AppComponent build();
    }
}

我已经添加了一个组件生成器，以获取外部依赖项

@Component
public interface AppComponent {

    @Component.Builder
    interface Builder {
        @BindsInstance
        Builder setContext(Context context);

        AppComponent build();
    }
}

现在，我可以在应用程序类中构建这个组件

    AppComponent appComponent = DaggerAppComponent.builder()
                                        .setContext(this)
                                        .build();

一切都很完美

现在我有了另一个组件，比如说

OtherComponet

@Component
public interface OtherComponent {
}

我想添加这个组件作为

AppComponent

@Component
public interface AppComponent {

}

@Component(dependencies = {OtherComponent.class})
public interface AppComponent {

    @Component.Builder
    interface Builder {
        @BindsInstance
        Builder setContext(Context context);

        AppComponent build();
    }
}

@Component(dependencies = {OtherComponent.class})
public interface AppComponent {

    @Component.Builder
    interface Builder {
        @BindsInstance
        Builder setContext(Context context);

        Builder setOtherComponent(OtherComponent otherComponent);

        AppComponent build();
    }
}

现在，如果我编译，我会得到错误

error: @Component.Builder is missing setters for required modules or components: [dagger.OtherComponent]
    interface Builder {

有道理。因为我已经覆盖了AppComponent和我的自定义组件的默认生成器。生成器没有用于设置

OtherComponent

实例的setter

因此，我将此方法添加到我的Custom.Builder中

@Component(dependencies = {OtherComponent.class})
public interface AppComponent {

    @Component.Builder
    interface Builder {
        @BindsInstance
        Builder setContext(Context context);

        @BindsInstance
        Builder setOtherComponent(OtherComponent otherComponent);

        AppComponent build();
    }
}

现在，如果我编译，我会得到完全相同的错误

error: @Component.Builder is missing setters for required modules or components: [dagger.OtherComponent]

这里怎么了？我已经用

@BindsInstance

给出了setter

setOtherComponent

，但为什么它仍然说

缺少所需模块或组件的setter

@Component
public interface AppComponent {

}

@Component(dependencies = {OtherComponent.class})
public interface AppComponent {

    @Component.Builder
    interface Builder {
        @BindsInstance
        Builder setContext(Context context);

        AppComponent build();
    }
}

@Component(dependencies = {OtherComponent.class})
public interface AppComponent {

    @Component.Builder
    interface Builder {
        @BindsInstance
        Builder setContext(Context context);

        Builder setOtherComponent(OtherComponent otherComponent);

        AppComponent build();
    }
}

注意：如果我没有选择自定义组件.Builder，那么dagger将为依赖组件生成Builder方法

例如：

这将创建一个生成器，可以像

 AppComponent appComponent = DaggerAppComponent.builder()
                            .otherComponent(otherComponentInstance)
                            .build();

---

在创建依赖组件时，您不需要放置

@BindsInstance

，它只能绑定

其他组件中公开的方法

@Component
public interface AppComponent {

}

@Component(dependencies = {OtherComponent.class})
public interface AppComponent {

    @Component.Builder
    interface Builder {
        @BindsInstance
        Builder setContext(Context context);

        AppComponent build();
    }
}

@Component(dependencies = {OtherComponent.class})
public interface AppComponent {

    @Component.Builder
    interface Builder {
        @BindsInstance
        Builder setContext(Context context);

        Builder setOtherComponent(OtherComponent otherComponent);

        AppComponent build();
    }
}

添加setOtherComponenet时是否尝试删除bindInstance？
