Issues with Maven Plugin for GWT

I tried using the Maven Plugin for GWT (https://tbroyer.github.io/gwt-maven-plugin/) with an existing project that I just upgraded to use GWT 2.9.0.

When I try running mvn run:codeserver, I get this:

[DEBUG] Arguments: com.google.gwt.dev.codeserver.CodeServer -workDir /Users/rflores/workspace/commonui/client-appmark-admin/target/gwt/codeserver -allowMissingSrc -src /Users/rflores/workspace/commonui/client-appmark-admin/src/main/java com.microfocus.am.Adminui

Does anybody know why?

I then tried to create a brand new project to see if I was missing something in my configuration by looking at the project created from the archetype. I did this:

$ mvn archetype:generate -DarchetypeGroupId=net.ltgt.gwt.archetypes -DarchetypeVersion=1.0.0 -DarchetypeArtifactId=modular-webapp

and I get this Error:

[WARNING] Error reading archetype catalog http://repo.maven.apache.org/maven2

org.apache.maven.wagon.TransferFailedException: Transfer failed for http://repo.maven.apache.org/maven2 501 HTTPS Required

 

In the case of my project, I can build it fine, so this isn't stopping me since I run SuperDevMode from IntelliJ (running fine too), but was wondering why I can't do it from the CLI with maven + plugin.
