I added a Global Maven setttings.xml in configuration file provider and named it : my-maven-global-settings.
When using Maven Pipeline withMaven clause, it ignores the name provided as globalMavenSettingsConfig argument:

withMaven(
     maven: "maven-3.3.9",
     globalMavenSettingsConfig: "my-maven-global-settings"
) {
...
}

The build because it cannot find settings.xml

As workaround I have to specify config file ID instead:

withMaven(
     maven: "maven-3.3.9",
     globalMavenSettingsConfig: "2bde3e90-eada-4573-9a33-bfeb95135d97"
) {
...
}

It works
