I have updated the version for Android version 2.0 to version 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 Fix plugin version and sync project options
The project is synchronized, but nothing happens.
When I click on Open File, it opens the build.gradle file, which is associated with the App module. it places the cursor on this line:
apply plugin: 'com.android.application'
Is there any clue what the ANDROID_DAILY_OVERRIDE environment variable is? or what could be this mistake?
