Error:Could not find property ‘assembleDebug’ on project ‘:app’

I am using '' and Android Studio 2.2 Preview 6. The build runs perfectly fine on Gradle 2.1.0, but to enable instant run it asks me to update Gradle plugin.

On updating Gradle plugin, the build shows "Error:Could not find property 'assembleDebug' on project ':app'". I already tried cleaning .gradle and .idea and reloading the project, but nothing works.

Please help.


  1. find which task is depending on assembleDebug task
  2. changing the following did the trick for me at least:


task findbugs(type: FindBugs, dependsOn: assembleDebug)


task findbugs(type: FindBugs, dependsOn: "assembleDebug")

so just surrounding the task with quotes was enough.
