Kotlin和Dagger2

Question

我正在尝试将Kotlin添加到我的项目中,但在启用Kotlin之后,我无法构建,因为Dagger2类不再生成.我尝试了第二个项目,我有同样的问题(实际上更糟糕的是,它抱怨Dagger2和DataBinding).

这些是我为Kotlin所做的改变:

项目build.gradle:

错误发生在这里:

sObjectGraph = DaggerObjectGraph
    .builder()
    .appModule(new AppModule(context.getApplicationContext()))
    .build();

其中不再定义DaggerObjectGraph.

任何帮助将不胜感激.

只需删除

kapt {
    generateStubs = true
}
