New

Create a new MAVEN project, create from archetype, select Maven-archetype-webapp

Next, fill in Groupid,artifactid and version

Next, adding a parameter to the properties archetypeCatalog=internal , without this parameter, will be very slow when Maven builds the skeleton, and sometimes it will get stuck directly.

Explanations from the Internet:

Archetypecatalog represents the plug-in uses the archetype metadata, does not add this parameter when the default is Remote,local, that is, the central warehouse archetype metadata, because the central warehouse archetype too much, so the result is very slow, Specify internal to indicate that only internal metadata is used.

Next, fill in the project name and module name.

Click Finish.
