android - Gradle DSL method not found: 'kapt()'

Question

Gradle DSL method not found: 'kapt()' Possible causes: The project 'jetpacklearn' may be using a version of the Android Gradle plug-in that does not contain the method (e.g. 'testCompile' was added in 1.1.0). Upgrade plugin to version 3.4.0 and sync project

The project 'jetpacklearn' may be using a version of Gradle that does not contain the method. Open Gradle wrapper file

My gradleVersion is '3.4.0', but can not deal with it , ask me the same question
