解决方案
android->build.gradle文件，修改ext.kotlin_version = ‘1.6.10’
classpath “org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version”

buildscript {
    ext.kotlin_version = '1.6.10'
    repositories {
        google()
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:4.0.0'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
