Could not initialize class com.android.build.gradle.AppPlugin

Question

when i upgrade AndroidStudio 2.1 to 2.2 and gradle 2.14 to 2.2, there has a gradle compiled error:

Error:Could not initialize class com.android.build.gradle.AppPlugin

Answer 1

If there are plugins specified in the project's gradle build files, check that they have been upgraded. I fixed this problem by upgrading com.github.hierynomus.license to the latest version.
