Answer 1

And mine has a different solution. I had a POM that had a entry for the jar without any , and it had a entry for the jar with a . Plus, the parent POM had a entry with the same . Apparently this confused Maven (3.3). The build worked fine, but the packaging did not.

Fix: remove entry in the child POM, and remove the from the entry in the child POM.

In code, here is the broken situation:

Parent pom.xml:

    
        
            org.apache.httpcomponents
            httpclient
            ${httpclient.version}
        
    


Child pom.xml:

    
        
            org.apache.httpcomponents
            httpclient
        
    

...

    
        org.apache.httpcomponents
        httpclient
        ${httpclient.version}
    

Post fix: parent POM is the same, child pom has just this

    
        org.apache.httpcomponents
        httpclient
