>                 URL: https://issues.apache.org/jira/browse/MNG-7754
>             Project: Maven
>          Issue Type: Task
>          Components: Core
>    Affects Versions: 3.9.1
>            Reporter: Tamas Cservenak
>            Assignee: Tamas Cservenak
>            Priority: Major
>             Fix For: 3.9.2, 4.0.0-alpha-6, 4.0.0
>
>
> Some users when see following warning:
> {noformat}
> [INFO] --- remote-resources:1.7.0:process (process-resource-bundles) @ maven 
> ---
> [WARNING] Parameter 'localRepository' is deprecated core expression; Avoid 
> use of ArtifactRepository type. If you need access to local repository, 
> switch to '${repositorySystemSession}' expression and get LRM from it 
> instead. {noformat}
> on their console, immediately grep their {{$HOME}} to find out that they DO 
> HAVE afore mentioned string present in their {{{}settings.xml{}}}, and then 
> scratch their head how to get rid of it.
> Hence, we should improve error message – at least add some clue that message 
> targets given Mojo developers (as message appears immediately under Mojo 
> execution log message) and not users. Best users could do is nag Mojo 
> developers, and not us, to make message disappear.
> Improvements:
>  * report at end, instead multiple times same warning (for reactor builds)
>  * possibility to suppress validation
>  * new check: maven-compat, maven2, p-c-d, mixed maven verions,, wrong scopes 
> (similar as m-p-p does on build time)
