I upgraded Android studio to 0.5.0 and mixed Java - Kotlin project stopped building. I tried creating a new clean project and even there Kotlin doesn’t work.
Using plugins version 0.7.5 and 0.7.86, I get the following error:
Error:A problem occurred configuring project ‘:app’.
> Could not resolve all dependencies for configuration ‘:app:classpath’.
> Could not find org.jetbrains.kotlin:kotlin-gradle-plugin:0.7.5.
Nothing changes if I change ext.kotlin_version = ‘0.7.5’ to ‘0.7+’
You can replicate this by creating new project in Android studio, adding a Kotlin file and agreeing with Android studio to add kotlin support. Note that Configure Kotlin in Project only lists kotlin 0.7.5 even though plugin version is different.
