Execution failed for task

Hi!

I’am following the basic Android tutorial but writing in kotiln instead.

Trying to build the app, i get the following error:

Error:Execution failed for task ':app:compileDebugJavaWithJavac'.> Unable to read class file: 'D:\Development\Java\MyApp\app\build\tmp\kotlin-classes\debug\de\domain\appname\DisplayMessageActivity$onCreate$message$1.class'

MainActivity

import android.content.Intent
import android.support.v7.app.AppCompatActivity
import android.os.Bundle
import android.view.View
import kotlinx.android.synthetic.main.activity_main.*

class MainActivity : AppCompatActivity() {
    companion object {
        const val EXTRA_MESSAGE:String = "de.domain.appname.MESSAGE"
    }

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
    }

    fun sendMessage(view: View?){
        val myIntent = Intent(this@MainActivity, DisplayMessageActivity::class.java)
        val message = editText.text.toString()
        myIntent.putExtra(EXTRA_MESSAGE, message)
        startActivity(myIntent)
    }
}

DisplayMessageActivity

import android.content.Intent
import android.support.v7.app.AppCompatActivity
import android.os.Bundle
import kotlinx.android.synthetic.main.activity_display_message.*

class DisplayMessageActivity : AppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_display_message)

        val myIntent:Intent = intent
        val message = myIntent.getStringExtra(MainActivity.EXTRA_MESSAGE)
        textView.text = message
    }
}

Of course i looked this up with google, but could not find anythin that would apply to my case (the path to the jdk is defined).

Any ideas?

Tried running the same code today and everything works fine…

Would still be intrested in finding the source of this error though.
