安卓gradle时报错"ERROR: Plugin with id 'com.android.application' not found."

buildscript {
    repositories {
        google()
        jcenter()
    }
    dependencies {
         //版本号请根据自己的gradle插件版本号自行更改
        classpath ‘com.android.tools.build:gradle:4.1.1‘
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}
