问题
I'm using android studio 2.4, And getting this error. Apparently I have to update my android plugin, but when I checked jcenter for new versions the only version
available was 2.5.0-alpha-preview-02. which would cause the exact same error.
I also see somewhere in the error message that it says I must replace the ANDROID_DAILY_OVERRIDE environment variable. But I really have no idea where to put this environment variable? Should it go to local.properties or is it an OS env variable? I was wondering if anybody else is facing this problem.
This is the full message
Error:(1, 0) The android gradle plugin version 2.5.0-alpha-preview-02 is too old, please update to the latest version.
To override this check from the command line please set the ANDROID_DAILY_OVERRIDE environment variable to "8d256f619ba96afd1273947e8b8bebea4cb2fd05"

On Windows it can be fixed by adding OS (or local user) environment variable with key "ANDROID_DAILY_OVERRIDE" and value "8d256f619ba96afd1273947e8b8bebea4cb2fd05" and restart Android Studio after that. After migrating to Android Studio 3.x it's better to remove this anvironment variable back.

There is a 40 day limit for beta/alpha versions and after that, Android Studio forces you to update to the latest version.
But it doesn't exist (the newest is the alpha with AS 3.0) so a possible solution is setting that environment variable, executing in the command line (in MAC):
launchctl setenv ANDROID_DAILY_OVERRIDE 8d256f619ba96afd1273947e8b8bebea4cb2fd05
And relaunch Android Studio

My solution in Ubuntu:
cd /etc
sudo gedit environment
add to end of 'environment' file: ANDROID_DAILY_OVERRIDE="your_value"
save and reboot
