When the 'mvn --help' command is used, the output for -U states "Forces a check for updated releases and snapshots on remote repositories". This confuses a lot of users into thinking that this option will update released versions of artifacts.
Could this be changed to something like "Forces a check for updated snapshots on remote repositories"
This would solve a number of problems that I have seen at different sites where people think they can patch a finally released artifact and it is updated in the local repository with the -U option.
Updating the help text would then roll into documentation where the text is copied into it.
