new
Create a new maven project, create from archetype, select maven-archetype-webapp
Next, fill in GroupId, ArtifactId and Version
Next, here add a parameter to Properties archetypeCatalog=internal. Without this parameter, it will be very slow when maven generates the skeleton, and sometimes it will be directly stuck.
Explanation from the Internet:
archetypeCatalog represents the archetype metadata used by the plugin. If this parameter is not added, the default is remote, local, which is the central warehouse archetype metadata. Because the central warehouse has too many archetypes, it is very slow. Specify internal to indicate that only internal metadata is used. .
Next, fill in the project name and module name.
Click Finish.
The directory structure of the project is as follows:
