The POMs in the new trunk don't set versions for dependencies on other arhiva modules. Maven has no issue with that when running mvn install.
I tried to do the same on my project and got error : Validation Messages: [0] 'dependencies.dependency.version' is missing for com.capgemini.quickstart:quickstart-model Reason: Failed to validate POM I don't see any special version setting in archiva. Did I miss something ? Nico.
