Profile inheritance

[David Jackman <Da...@fastsearch.com>]

I've searched the mail archives, and this question seems to be asked a
lot and answered never.
 
Are profiles inherited from parent poms?  The scant (and confusing) docs
seem to imply that they are, but doing a help:active-profiles command
does not agree with this.
 
Please someone explain how this is supposed to work.

Hello, 
As a follow-up to John Casey's post, I can tell that according to my
own experiences:
 - profiles are not inherited per se (see JC's post) but their effects
 are
 - if you have profiles with the same id in several poms (and
 settings.xml), they are all activated in their own poms when invoking
 the build. Sort of method overloading ...

HTH,

Profiles are not inherited, period.

Now, having said that, profiles in parent POMs can be triggered by the
building of a child. When activated, they are applied directly to the parent
POM, prior to that parent being used for inheritance into the child. So, the
effects of an active profile in a parent POM will be felt by the child.
Also, since a parent's profile is applied to it before inheritance
calculations take place, inheriting the profile itself (and presumably,
re-applying it at the child level) would lead to double-application of that
profile.

It's a little bit of a confusing topic, so I'm sorry if that explanation is
a bit jumbled. I hope if makes sense now.
