Android studio 2 issue after update to preview 6

Question

I updated to android studio 2.0 to preview 6.

I got this error message:

Error:(1, 0) Plugin is too old, please update to a more recent version, 
     or set ANDROID_DAILY_OVERRIDE environment variable to "aed79d567e57792ed352e708d2b7ca891ff897c6"

When i click on the options Fix plugin version and sync project

Project get synced but nothing happens.

When i click on Open File, it opens build.gradle file which associated to App module. it puts the cursor on this line:

apply plugin: 'com.android.application'

Any clue what is the ANDROID_DAILY_OVERRIDE environment variable ? or what can be this error ?

Answer 1

Could you try changing the class path of your build.gradle to com.android.tools.build:gradle:2.0.0-alpha6

buildscript {
repositories {
    jcenter()
}
dependencies {
    classpath 'com.android.tools.build:gradle:2.0.0-alpha6'
}
}

hope this will help.
