错误：Module was compiled with an incompatible version of Kotlin. The binary version of its metadata

androidstudio升级kotlin之后，build时gradle就爆出了错误： Module was compiled with an incompatible version of Kotlin. The binary version of its metadata is 1.5.1, expected version is 1.1.16.

大概意思是Kotlin版本编译不兼容导致，我根据现有的版本,将build.gradle里面的ext.kotlin_version 改成 '1.5.31'就可以了，这个版本是怎么回事，暂时没有研究

buildscript {
    ext.kotlin_version = '1.5.31'
    repositories {
        google()
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.5.0'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}
