it would be very nice if you could test the case below:
pom.xml (
parentpom (parent pom for module1 and module2)
-- pom.xml
module1
-- pom.xml
module2
-- pom.xml

> When using Maven2, the recommended directory structure for a multi-module
> build is hierarchical, e.g.:
> - pom.xml (parent pom of all modules)
> --- module1
> +-- pom.xml
> --- module2
> +-- pom.xml
> etc
> When using such a structure with continuum, if a change is committed in
> module28, then EVERY module will be rebuilt: indeed the parent pom will be
> rebuilt because the change is "under" its scm tree, and all the other modules
> will therefore we rebuilt because of a "dependencies change" on the parent
> pom. This can easily multiply the build time by a factor of 10 or 20.
> I have attached a patch. It considers that the parent has "changed" only if
> its pom.xml has changed. Not sure it is perfect, but it works for me (the
> patch has been tested (against continuum-1.1 and trunk). Feel free to rewrite
> or modify it as much as you like.
