Whereas

composer push --url=https://repositories.XXX.com/repository/XXXX/ --username=XXXX --password="XXXX" 1.0.22

Returns success:

Archive correctly pushed to the Nexus server

Expected

• If composer push command requires full URL (protocol + URI), command should fail by throwing an appropriate error message instead of displaying cURL error message

basically it could use filter_var() to make sure URL is valid
