I have a maven build and when the database changes we need to rebuild a specific project because it auto-generate some files, so I need some kind of conditional execution. I heard people talking about profiles, but in my case we are in the same profile (development) and just sometimes we need to build a specific module. I wish for something like maven clean install -Dspecific.build and some configuration in the pom to build this additional module. Is there something like that in maven?

    You can use multiple profiles together and each can have different activation conditions. – billc.cn Sep 10 '12 at 19:21
  • And how do I execute multiple profiles together? – islon Sep 10 '12 at 19:31

    mvn -Pprofile1,profile2,profile3..... – Peter Svensson Sep 10 '12 at 19:47
  • Thanks, that's a really nice solution. Anyway my build order got messed up when I do that. Instead of building modules X, Y, Z, W (where Y is the build to be executed conditionally) I got X, Z, W, Y no matter the order I pass to -P (-Pdev,special or -Pspecial,dev) and my build fails. – islon Sep 10 '12 at 19:51
  • Build order is based on dependency resolution, so you should examine how your modules depend on each other. – noahlz Sep 10 '12 at 19:58
  • Ok, I got it. It wasn't dependency resolution it was the profile order in the pom: 'special' should come first. billc.cn, if you put your comment as an answer I'll accept it. – islon Sep 10 '12 at 20:03

    If I understand your question correctly, you can use Maven's new Advanced Reactor Options, see answer [here](http://stackoverflow.com/questions/11620566/how-to-activate-a-maven-profile-for-a-specific-module-in-a-mutli-module-project/11624416#11624416) for more details. – yorkw Sep 10 '12 at 21:46
