Using the latest Android Studio 3.0 Canary 5
Here's the error:
Error:(1, 1) A problem occurred evaluating project ':app'.
Failed to apply plugin [class 'com.android.build.gradle.api.AndroidBasePlugin'] Android Gradle plugin 3.0.0-alpha5 must not be applied to project [path_to_my_project] since version 3.0.0-alpha5 was already applied to this project
Tried: cleaning, rebuilding, opening/closing. Not working.
any ideas ?
[LATER EDIT] Solution: Migrate to Canary 8+ and all should be ok.
