I don't know exactly what you mean, with build number. I am using
something like the attached mojo.
This creates a build number in a file and increments it for every build
you started.

What SCM are you using?

Thanks. Is there a way to increment build version numbers without the
involvement of SCM (SCM is involved in release plugin)?

Karthik.

maven-release-plugin is the one but it increaments all modules.

Hi,
With every build I do for my J2EE project, I want the version of all
modules
to be automatically incremented. What is the best way of accomplishing
this?
Also is there a way to increment the version numbers only for modules
which
have had changes?
Thanks and regards,
Karthik.
