Unsupported method: AndroidProject.getPluginGeneration() while running project

I encountered this error in Android Studio 2.2, in my case it was cause by AS checking availability of the Instant Run feature. I fixed it by disabling Instant Run:

Android Studio -> Preferences -> Build, Execution, Deployment -> Instant Run

General Issue:-

It can occur because AS was checking availability of the Instant Run feature. The fixed is to disable Instant Run:

Windows & Linux:

File -> Settings -> Build, Execution, Deployment -> Instant Run.

Mac:

Android Studio -> Preferences -> Build, Execution, Deployment -> Instant Run.

Thanks to @pophus for mentioning this.

Use this Steps If you are using a butterknife:-

If you are using the new Jack compiler with version 2.2.0 or newer, you do not need the 'android-apt' plugin and can instead replace apt with annotationProcessor when declaring the compiler dependency.

That is, remove

classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'

from your main gradle file

And remove

apply plugin: 'android-apt'

from your main module file

and replace

apt 'com.jakewharton:butterknife-compiler:8.4.0'

with

annotationProcessor 'com.jakewharton:butterknife-compiler:8.4.0'
