Error running Android (written in Kotlin) project

Question

When compiling the project with the new gradle2.0.0-alpha pluggin I'm getting.

java.lang.RuntimeException: 
  Unable to instantiate application com.android.tools.fd.runtime.BootstrapApplication: 
  java.lang.ClassNotFoundException: 
    Didn't find class "com.android.tools.fd.runtime.BootstrapApplication" on path:
    DexPathList[[zip file "/data/app/com.inoutdelivery.enfesta-1/base.apk"],nativeLibraryDirectories=[/vendor/lib, /system/lib]]

Any ideas?

Answer 1

On a non-Kotlin Android project, I was running into this same problem. I solved it by turning Instant Run off (Preferences -> Build, Execution, Deployment -> Instant Run -> Enable Instant Run), running my app, and then turning Instant Run back on.

Instant Run isn't working for me as advertised, but this at least got the app to build on 2.0.0-alpha.
