Android Studio throws build error in Kotlin project which calls static method in java interface

Question

I have a Kotlin project in Android Studio. I am calling a static method in Java interface from the Kotlin code. The build fails with the error,

Calls to static m         


        

Answer 1

I had the same problem because I had a folder for the integration tests different than the unit test folder. So the build.gradle needs more configuration:

compileKotlin {
    kotlinOptions.jvmTarget = "1.8"
}
compileTestKotlin {
    kotlinOptions.jvmTarget = "1.8"
} 
//added this
compileIntegrationTestKotlin {
  kotlinOptions.jvmTarget = "1.8"
}
