Bummer! Error: Unable to access jarfile test.jar

I'm lost when it comes to this error message

FunFactsActivity.kt 
import android.app.Activity
import android.os.Bundle
import android.widget.TextView
import android.widget.Button

class FunFactsActivity : Activity() {
  override fun onCreate(savedInstanceState: Bundle) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_fun_facts)

    // Declare our View variables and assign them the Views from the layout file
    val factLabel = findViewById(R.id.factTextView) as TextView
    val factLabel = findViewById(R.id.showFactButton) as Button

  }
}

val showFactButton = findViewById(R.id.showFactButton) as Button

The name of the second variable is "showFactButton" not "factLabel"
