Maven: how to install the plugin offline

I am sitting behind a firewall and therefore maven cannot connect to the central repositories (error message is given below).

However, I can connect to the Internet through HTTP.

How to install the maven plugin (e.g. archetype) offline (for example, load some file in a browser and then install the plugin by running some commands)?

Thanks in advance

Dmitry

I assume that your security firewall does not allow you to download maven from the central repository. That way, you can simply specify the mirrors in the settings.xml file in maven_home. if you have any repository for your company called nexus, specify the URL of this communication server in the mirror section in your settings.xml. Please note that if you do not have a repo for your company, you need to download all the dependencies offline and install it using the mvn installation in the local repository on your build server.
