构建的时候会有个警告

Android如何指定kotlin版本
根目录的build.gradle
buildscript {
repositories {
google()
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:4.0.1'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.4.0"
}
}
参考Dependency on the standard library added by default，不需要在每个模块
implementation "org.jetbrains.kotlin:kotlin-stdlib:1.4.0"
这里指定kotlin的版本是1.4.0，但是看上面的报错版本是1.4.10和1.5.31，这是为什么呢
版本依赖关系
执行下面的命令看看debug的依赖
./gradlew :app:dependencies -q --configuration debugRuntimeClasspath
结果如下
------------------------------------------------------------
Project ':app'
------------------------------------------------------------
debugRuntimeClasspath - Runtime classpath of compilation 'debug' (target (androidJvm)).

我们这里分析一下我们指定的版本是1.4.0，为什么kotlin-stdlib、kotlin-stdlib-common版本最终变成了1.5.31，kotlin-stdlib-jdk7、kotlin-stdlib-jdk8版本为1.4.10
com.adcolony:sdk:4.7.0依赖的org.jetbrains.kotlin:kotlin-stdlib:1.5.31版本最高，同时也比我们指定的1.4.0高，所以确定了kotlin-stdlib的版本为1.5.31，同时导致kotlin-stdlib-common的版本也是1.5.31
com.squareup.okhttp3:logging-interceptor:4.9.0依赖的org.jetbrains.kotlin:kotlin-stdlib-jdk8:1.4.10只有一个版本，同时也比我们指定的1.4.0高，所以确定了kotlin-stdlib-jdk8版本为1.4.10，同时也导致kotlin-stdlib-jdk7版本为1.4.10
提升kotlin版本
所以解决方案就比较简单了，提升下kotlin版本到1.5.0试试
org.jetbrains.kotlin:kotlin-stdlib-common:1.5.31
org.jetbrains.kotlin:kotlin-stdlib:1.5.31
org.jetbrains.kotlin:kotlin-stdlib-jdk8:1.5.0
org.jetbrains.kotlin:kotlin-stdlib-jdk7:1.5.0
这时候虽然看起来还是不统一，但是没有警告了，问题解决
提升下kotlin版本到1.5.31试试
org.jetbrains.kotlin:kotlin-stdlib:1.5.31
org.jetbrains.kotlin:kotlin-stdlib-common:1.5.31
org.jetbrains.kotlin:kotlin-stdlib-jdk7:1.5.31
org.jetbrains.kotlin:kotlin-stdlib-jdk8:1.5.31
