Karl Heinz Marbaise commented on MNG-6279:
------------------------------------------

Have you checked that with most recent version of Maven (3.5.2)? 

> -pl <module> at *end* of command line should raise a warning

>                 Key: MNG-6279
>                 URL: https://issues.apache.org/jira/browse/MNG-6279
>             Project: Maven
>          Issue Type: Bug
>          Components: Command Line
>    Affects Versions: 3.0.5
>         Environment: Ubuntu 14.04.3 LTS
>            Reporter: Chris Hennick

> I recently tried to run tests on only one specific module using this shell 
> script:
> {code:sh}
> #!/bin/sh
> mvn jacoco:prepare-agent -pl betterrandom &&\
> mvn test -pl betterrandom &&\
> mvn jacoco:report -pl betterrandom &&\
> if [ "$TRAVIS" = "true" ]; then
>   mvn coveralls:report -pl betterrandom
> fi
> {code}
> It took me a long time to find out that the -pl <module> option needed to 
> come *before* the goals it was to apply to. Since -pl <module> with no goals 
> after it can't have any effect, it's almost certainly a sign that the 
> command-line parameters are out of order. And since this is such an easy 
> mistake to make when one's new to multi-module Maven projects, the invocation 
> should raise a warning along the lines of "-pl <module> in this position has 
> no effect. To filter a goal to a specific module, it must come *before* that 
> goal on the command line. Did you mean mvn -pl <module> <goal...>?"
