Toss it out for a while and finally settle it,
Probably because of a network problem.
XML has never been accessible
Maven skeleton build project slow and outrageous, all in the generating project in Batch mode Wait, the idea status display bar is not runing, and no card dead. View debug information found, is maven get archetype-catalog.xml caused. (It takes a long time to get to the http://repo1.maven.org/maven2/archetype-catalog.xml with the viewer.) )
XML can't download so
The first step I downloaded this skeleton xml elsewhere, put it locally (your directory default. m2) \repository\org\apache\maven\archetype\archetype-catalog\2.4
The second step modifies the project default settings join command-darchetypecatalog=local
Then the XML problem solved is the download speed problem,
I'm connected to the VPN.
Executed a mvn archetype:generate-darchetypecatalog=local in cmd
Download speed is good, a few minutes later the download is complete,
Then go to create the project, after downloading a few packages, prompted to build success!
(Starting from scratch Java development) Idea+maven build a WebApp skeleton project (to solve the problem that has been downloading)
