compileOptions { 
                    sourceCompatibility kotlin_version 
                    targetCompatibility kotlin_version 
}

Answer 1

After hours of working on this probleme, I solved it by including the following within app/build.gradle:

android { 
        compileOptions { 
                sourceCompatibility JavaVersion.VERSION_1_8 
                  targetCompatibility JavaVersion.VERSION_1_8 
          }
}
