Maven: Non-resolvable parent POM

Question

I have my maven project setup as 1 shell projects and 4 children modules. When I try to build the shell. I get:

[INFO] Scanning for projects...
[ERROR] The b         


        

Answer 1

Alternative reason also might be the parent artifact comes from repository which is not accessible from pom.xml, typically private repository. The solution was to provide that repository in pom.xml:

    
        internal-repo
        internal repository
        https://my/private/repo
        default
        
            true
        
        
            true
        
    

In my case the problem was even more complicated due to Eclipse: the repository was active only in special profile (activate-private-repo...) and Maven GUI in Eclipse didn't allow to set this profile through Ctrl+Alt+P shortcut.

The solution was to temporarily declare repository outside profile (unconditionally), launch Alt+F5 Maven Update Project, activate profile and put repository declaration back into profile. This is rather Eclipse bug, not Maven bug.
