[jira] (MNG-5230) Command line option to exclude modules from reactor

["Stephan Pauxberger (JIRA)" <ji...@codehaus.org>]

    [ https://jira.codehaus.org/browse/MNG-5230?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=308997#comment-308997 ] 

Stephan Pauxberger commented on MNG-5230:
-----------------------------------------

Just to add my two cents:

This would be especially useful for automated ci-builds, i.e. to exclude archives from the build, which usually take a long time to build but do not offer any value to a ci build. Right now, I use the profile axis model described in http://www.blackbuild.com/how-to-really-use-maven-profiles-without-endangering-your-karma/ using a separate profile for ci jobs (which i would continue to use, but differently).

Another option would be to be able to exclude modules not only in the command line, but in a profile as well, something like:

<profile>
  <id>ci</id>
  <modules>
    <module>!ear</module>
  </modules>
</profile>

or (perhaps better, but requiring a change of the model)

<profile>
  <id>ci</id>
  <excludedModules>
    <excludedModule>!ear</excludedModule>
  </excludedModules>
</profile>

> Every now and then I want to exclude one or more modules from a rather large reactor build.
> One reason for this can be: The respective module has tests that take long time to execute and I know that I don't need to execute them.
> Introducing yet another profile for this is not desirable for various reasons.
> So, something like an opposite to -pl would come in handy. Let's say "-el" for "exclude list".
> Example:
> {code}
> root
>   + module a
>     + module a1
>     + module a2
>   + module b
>     + module b1
>   + module c
> {code}
> Calling _mvn -el a1,c_ would build all modules execpt a1 and c.
