Duplicate name in parent and current
Hi,
I have a situation in which the dir names are same.
Example:
/base
/base/modA
/base/modA/modA
I get the following error while trying to run mvn compile. The code for 2
POM's is below. What should I change in the parent to make this work ?
Thanks,
Reason: Parent element is a duplicate of the current project for project
com.co.t3:modA

I think it's the duplicated artifactId's that is causing the problem. Maybe the
artifactId of the pom in the subdirectory modA/modA should be set to "modA-modA"
or something like that.

Re: Duplicate name in parent and current
Posted by Stephen Connolly <st...@gmail.com>.
You cannot have two modules in the reactor with the same groupId and
artifactId...
from your pom snippets it looks like this is the case...
consider changing either the groupId or the artifactId of one of the modA's
(Note that the artifactId does not have to be the same as the directory
name... it's just that it's nicer if it is ;-) )
