Requests to http://repo1.maven.org/maven2/ return a 501 HTTPS Required status and a body [duplicate]

Answer 1

Beware that your parent pom can (re) define repositories as well, and if it has overridden central and specified http for whatever reason, you'll need to fix that (so places to fix: ~/.m2/settings.xml AND also parent poms).

If you can't fix it in parent pom, you can override parent pom's repo's, like this, in your child pom (extracted from the 3.6.3 default super pom, seems they changed the name from repo1 as well):

  
    
      central
      Central Repository
      https://repo.maven.apache.org/maven2 
      default
      
        false
