ClassNotFoundException的定制香精使用科特林 [英] ClassNotFoundException in custom flavor using kotlin

问题描述

我定义我自己的味道，并设置sourceSet：

I defined my own flavor and set sourceSet:

sourceSets {    
    main.java.srcDirs += 'src/main/kotlin'           // WORKS
    myflavor.java.srcDirs += 'src/myflavor/kotlin'   // DOESN'T WORK
}

这是我的项目结构：

here is my project structure:

但是...我收到以下错误：

but... I receive following error:
