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).
这些是我为启用Kotlin所做的改变：

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.
解决方法
只需删除
kapt {
generateStubs = true
}
