leodeleon: Are you sure the compiler version aligns with the com.android.tools.build:gradle version?

[leodeleon]

Yes

[tmiyamon]

Do you have apply plugin: 'kotlin-kapt'?

Now I have this problem

[leodeleon]

Error:Circular dependency between the following tasks:
:app:compileDebugKotlin
\--- :app:kaptDebugKotlin
     \--- :app:compileDebugKotlin (*)
(*) - details omitted (listed previously)

[enighma]

I can try help you later today, swamped with work now. It is possible to make it work, we use dagger2, databinding and kotlin in our project without problems.

[leodeleon]

yeah, I’m trying to convert this sample project

[tmiyamon]

your gradle is 2.3.2 but dataginding is 2.2.3

[igoticecream]

Kapt{} should be outside android{} right?

[tmiyamon]

kapt { generateStubs = true } is no longer needed.
