C:\Users...\kotlin-stdlib-jre7-1.2.41.jar: kotlin-stdlib-jre7 is deprecated. Please use kotlin-stdlib-jdk7 instead

出错地方 module build.gradle

implementation "org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version" 会显示已经过时

将 org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version 改为 org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version

并编译。
