Exhibits a problem with compiling a project with scala-maven-plugin 4.2.4 on Windows.
Tested with Oracle jdk 8
Change scala-maven-plugin version to 4.2.0 or 3.3.2 and it will compile fine.
This sample project was created via mvn archetype:generate from net.alchim31.maven:scala-archetype-simple version 1.7.
I only changed the version number of the scala-maven-plugin to 4.2.4
Here's the full error that's occuring:
