Hi,
I modified all prefix "compiler" to "compiler1" in all the maven-metadata-${repoId}.xml. But when I run "mvn compiler:compile", it still works. And If I run "mvn help:describe -Dplugin=compiler", it fails due to failing to find the plugin. I wonder why the former works normally? How does maven succeed to resolve the prefix "compiler" since I have changed it to "compiler1"?
