Subject 答复: [vfs] How can find the maven repository of commons-vfs , and how can develope the filesystem protocol for myself?
Date Tue, 18 Dec 2012 08:42:56 GMT
Hi, Ralph:
	Thanks for your reply. 
	There may be some wrong for my maven connecting to the central repo.
	But I can access this address in my IE:
https://repository.apache.org/content/groups/snapshots/, and there is no one
item "commons-vfs" 
	So I think is there some wrong for the maven repo of apache commons?
	
	Sincerely  Appreciate!

Ye,

This error seems to indicate you are having connectivity issues getting to
the Maven central repository. I'm not sure how we can help with that.

Why? What error are you getting. Again, the 2.0 version should be
downloadable from the Maven central repository.  The 2.1 snapshot may not
have ever been deployed to a Nexus repository.  In that case you should just
run mvn install from the command line to build it.  However, if Maven can't
connect to the central repository not much is going to work.  Perhaps you
have a local proxy for Maven Central?
