[INFO] The plugin 'org.apache.maven.plugins:maven-archetype-plugin' does not exist or no valid version could be found

Answer 1

You might want to check your internet connection (but you posted here somehow, so I guess it's OK).

Then take a look at Maven docs about user settings; if you're behind a firewall/NAT, then you probably need to add proxy definition inside the <proxy> tag.

Answer 2

Read here on how to connect to maven from a proxy . Try updating after that it will work.

Answer 3

Another possibility is that your organization firewall/proxy prohibits downloading of jars. You can verify that by trying to download the jars through a browser. If you get an error, then you may want to work with your IT folks to fix it.
