working around maven error: Project 'XYZ' is duplicated in the reactor

Question

I'm creating a multi-module project that builds many other, related projects. Some of these projects are multi-module projects as well, and in some cases they build the same sub-project. Maven yells at me, but this is intentional and I'd like it to build anyway.

Has anyone worked around this? Thanks.

Answer 1

For me <artifactId> was same for 2 different module in their pom and that caused this error.
Once changed, it worked fine .
