Hi everyone, I tried to use 

<http://kotlin.io|kotlin.io>.path.createTempDirectory()

 to create temporary directory on my kotlinc 1.4.31 but failed on Windows, WSL2 and Mac. In the Kotlin playground web,  the code raises `SecurityException`(which is correct) but all my systems (including kotlinc and intelliJ IDEA) cannot resolve the package 

kotlin.io.path

 . Is there anything I need to do to use the 

kotlin.io.path

 package?

are you targeting jvm 8? (should be the default now, https://kotlinlang.org/docs/whatsnew15.html#new-default-jvm-target-1-8 but checking just in case)

I'm using JVM 16. Anyway, I found the reason. The extensions are available in the 

kotlin-stdlib-jdk7

 module. So I need to put the jar file to the classpath or add the dependency to

kotlin-stdlib-jdk7

or `kotlin-stdlib-jdk8`(which transitively depends on the

kotlin-stdlib-jdk7

).

the jdk used to compile does not have to match the compilation target jvm
