Version

4.0.0-milestone5

Context

I encountered an exception which looks suspicious while gradle execute kaptKotlin.

A Gradle build scan is available here.

Caused by: java.nio.file.InvalidPathException: Illegal char <:> at index 2: /C:/workspace/moumoux/Outles/build/tmp/kapt3/classes/main/PathForCodeGenProcessor.class

Do you have a reproducer?

A reproducer is a simple project hosted on GitHub (or another forge supporting git clone operation) that has a build file that can be executed to reproduce the issue.

Reproducers are very helpful for contributors and will likely help them fixing your bug faster.
