The GH Action Scripts for Windows do not run correctly. For example, the formatting script does not make it past the call to run the p2 site
"mvn p2:site"

I'm guessing there are some syntax issues in the script.

Script:
https://github.com/openjdk/jmc/blob/master/scripts/checkformatting.bat

Example run:

https://github.com/jiekang/jmc/commit/ca9102e217958b8e5f3064ef6511ded27b015e8f/checks?check_suite_id=351610527

Note the formatting fails on linux/mac but passes on windows. It passes because spotless was never executed.
