It’s hard for me to understand the difference between a mirror and a proxy server defined in settings.xml. I read that no matter what the mirrrorOf mirror is defined, all HTTP requests to these (mirrorOf) repositories are overridden by the corresponding HTTP request to the mirror. What is a proxy? This question arises after fixing the following error that I get when I try to create a new project using mvn archetype: generate.
The plugin 'org.apache.maven.plugins: maven-archetype-plugin' does not exist or not a valid version
Any help?
