Maven uses archetypes to create custom project structures, forming Maven project templates. In the previous chapter we learned that Maven uses the following command to quickly create java project: mvn archetype:generate * * * ## What is an archetype? An archetype is a Maven plugin, or more precisely a project template, whose task is to create a project structure based on the template. We will use the quickstart archetype plugin to create a simple java application. * * * ## Using Project Templates Let us open the command console, go to the C:> MVN directory and execute the following mvn command: C:MVN> mvn archetype:generate Maven will start processing and ask you to select the desired archetype: Scanning for projects...
