[jira] [Commented] (MNG-7051) Optionally skip non-existing profiles

["Slawomir Jaranowski (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MNG-7051?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17261340#comment-17261340 ] 

Slawomir Jaranowski commented on MNG-7051:
------------------------------------------

Please consider adding profile prefix {{?}} to current version {{3.6.x}}

I have in infrastructure about 200 maven projects, before upgrade maven binary in CI infrastructure I need to do some of upgrade in projects.

So it will be easier if I can use {{?profile-name}} and {{profile-name}} in {{3.6.x}} with the same result.

> For Maven 4, the behaviour of the {{-P}} command line option will change:
>  * {{-P apache-release}} will activate the *apache-release* profile. If such a profile cannot be found, the build will break.
>  * {{-P ?apache-release}} will activate the *apache-release* profile. If such a profile cannot be found, the build will continue but log a warning.
> {color:#ff0000}
> Note that this breaks the current behaviour of Maven 3 in two ways:
> {color}
> # {{-P apache-release}} will currently log a warning and not break the build. That behaviour can be restored by adding the {{?}}.
> # A profile that has an identifier that not valid (i.e., contains anything else than {{a}} - {{z}}, {{A}} to {{Z}}, {{0}} - {{9}}, {{-}}, {{_}} or {{.}}) will break the build.
