Maven Archetype Catalog

Having some trouble getting a remote archetype catalog created. I figure it could be automatically managed by maven when I push an archetype but there doesnt seem to be good documentation around it. I'm using AWS CodeArtifact as my remote repo, which means I need to have all files inside a package, where the docs outline the archetype-catalog.xmlshould be at the root of the repo Anyone have any experience with this?...

Hey guys,

I am trying to sort a String Array by the length of it's elements. I found only this solution: Arrays.sort(strs, Comparator.comparing(String::length)). Is there a more 'elegant' way to do it (strs is the name of the Array)?
