Wrong Path Formatting of MAVEN_ARGS variable on Windows

[alfeilex]

Expected behavior

Environment variables on Windows should be in windows path format:
MAVEN_ARGS=-s C:\projects\dev\conf\mvn\settings.xml

Actual behavior

MAVEN_ARGS=-s /c/projects/dev/conf/mvn/settings.xml is not in windows path format on Windows.

Steps to reproduce (bug)

1. Install mvn and try to run mvn clean
2. That error should occur:

ide mvn clean
[ERROR] Error executing Maven.
[ERROR] The specified user settings file does not exist: C:\c\projects\dev\conf\mvn\settings.xml

3. The reason for that might be the wrong format MAVEN_ARGS value as described in behaviors

Affected version:

• OS: Windows
• Shell: GitBash

@alfeilex
Why do you think, this is a bug?
Maven is called via mvn.bat on Windows and need a Windows standard PATH rather than a MSYS path.
Is something going wrong with the current state?
IMHO it is a bug to change this...

I was not reading carefully and thought the opposite.

BTW: This is the issue I should have intervented and that caused the problem:
#321

ide mvn clean
[ERROR] Error executing Maven.
[ERROR] The specified user settings file does not exist: C:\c\projects\dev\conf\mvn\settings.xml

OK. I was able to reproduce this. So there is indeed a bug.
Why does that bug occur when maven is called via IDEasy but not when maven is called directly.
Is this actually a bug in MSYS or is there a bug in our code that tries to convert PATH values from MSYS syntax to Windows syntax and produces this C:\c\ path?
Your PR may be valid and fix this, but I still want to really understand what is going wrong here...

UPDATE: I tried to debug this in Intellij and noticed that the error is not reproducible there. So actually a bug of graalvm?

I would disagree. This is a totally different issue.

For the record: IMHO this is related to this problem: https://issues.apache.org/jira/browse/MNG-8018

Expected behavior
Environment variables on Windows should be in windows path format

This expectation is also wrong. In git-bash we need MSYS path syntax instead of Windows syntax to make it work.
This is the difference of

ide env

called in CMD vs.

ide env --bash

called in git-bash.

As we can see supporting Windows with CMD and git-bash is rather tricky.
