master does not build on windows with Maven 4.0.0-rc-3

[Bukama]

Affected version

4.0.0-beta-3-SNAPSHOT

Bug description

I wanted to update parent version, but I got test errors. So I tried to build master and got the same error too.

When trying to build current master (4.0.0-beta-3-SNAPSHOT) as of commit 7d44073 the build breaks on my Windows machine

I think that this is a duplicated of #326. The master is known to not compile against Maven 4.0.0-rc-3. This is already fixed in pull request #320, which is waiting since April 6th for a volunteer to review it.

I cloned the branch of your PR and get the same error there.

Needed to run as admin, as one other test otherwise fails due to execution rights.

[desruisseaux]

This error didn't occurred in the GitHub action, including on Windows. What is the full name of the directory where the plugin has been cloned on your machine? For checking if there is a special character which appears when the plugin converts a path to an absolute path.

[desruisseaux]

Correction: maybe no need to provide the full path. Looking at the line where the error occurred, I think that this is an encoding issue. What is the encoding of your Windows system? Can you check if System.getProperty("native.encoding") returns the right encoding on your system?

[Bukama]

Path of my plugin fork:

D:\Github\Maven\maven-compiler-plugin

path of the clone of your PR

D:\Github\Maven-Official-Testwiese\maven-compiler-plugin

Output

C:\Windows\system32>jshell

|  Geben Sie für eine Einführung Folgendes ein: /help intro

jshell> System.getProperty("native.encoding")
$1 ==> "Cp1252"

jshell>

[desruisseaux]

Thanks. I wll try tomorrow to add a commit using the encoding returned by System.getProperty("native.encoding") for parsing the file produced by the forked compiler.

Should be fixed in commit 7bac7a5. Can you try again please?
