Unresolved reference: DaoSession using greendao and kotlin

Question

I am trying to convert a android project written in java to kotlin. My greendao class have been generated by anytime i build i get a Unresolved reference: DaoSession error message. I have
kapt { generateStubs = true } in my build gradle code.

Answer 1

Move your greendao plugin before the kotlin plugin in your app build.gradle like below:

apply plugin: 'org.greenrobot.greendao'

apply plugin: 'kotlin-kapt'
apply plugin: 'kotlin-android'

Answer 2

This is caused by that Greendao generate DaoSession and other Dao files at a default path:"app/build/generated/source/greendao/", which cannot be found by kotlin.

So you just need to change the Dao path by adding this code to your module Gradle file:

greendao {
    targetGenDir 'src/main/java' 
}

Then, you can find the Dao files like DaoSesson.java are generated in your project path 'src/main/java'. Now Kotlin can find the DaoSession.

Hope can help.
