Warning during maven package

[alanorth]

I get this warning during maven packaging:

$ mvn package

I'm not the person who originally wrote the Maven build XML, but I remember him telling me it's really a mess to get it to work (I had a chance to confirm that on occasions when I had no choice but to amend it). And since I'm not a Maven pro, my policy here is to live with the warning.

I think the problem is we have a default build section that requires executing some commands, and a second, profile-scoped, build, that also requires executing some commands. I really don't know why Maven wouldn't let users launch commands several times during the build (unless it's actually possible if configured differently?). Maybe a different plugin could be used to workaround that issue?

I'm afraid I'm not going to be able to dig into this in a near future. If a Maven wizard wants to submit a solution, I'll be happy to merge it.
