问题描述

提示：在项目build的时候报了以下错误：
kotlin-stdlib-common.kotlin_module: Module was compiled with an incompatible version of Kotlin. The binary version of its metadata is 1.6.0, expected version is 1.4.2.

解决方案：

在项目工程下的build.gradle中，将ext.kotlin_version 改成 ‘1.6.0’

buildscript {
    ext.kotlin_version = '1.6.0'
    repositories {
        google()
        mavenCentral()
  }

    dependencies {
        classpath 'com.android.tools.build:gradle:4.1.0'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
  }
}

allprojects {
    repositories {
        google()
        mavenCentral()
  }
}

rootProject.buildDir = '../build'
subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"
}
subprojects {
    project.evaluationDependsOn(':app')
}

task clean(type: Delete) {
    delete rootProject.buildDir
}
