[WARNING] while trying to generate maven archetype with "mvn archetype:generate -DarchetypeCatalog=http://cometd.org"

[steven winner]

Is there something going on with the cometd maven catalog?  I've never had this issue before while trying to generate a skeleton with:

This is the warning I'm seeing:

[WARNING] Error reading archetype catalog http://cometd.org
org.apache.maven.wagon.TransferFailedException: URI does not specify a valid host name: http:/cometd.org

at org.apache.maven.archetype.source.RemoteCatalogArchetypeDataSource.downloadCatalog(RemoteCatalogArchetypeDataSource.java:119)

It doesn't quite, but it doesn't provide the different archetype to select.  Is there a way to specify the archetype you wish to use in the mvn command?  

I'm trying to generate a skeleton using "org.cometd.archetypes:cometd-archetype-spring-jquery-jetty9"

Nevermind.  I was able to generate it using local instead of http://cometd.org

Works for me with both http:// and https://.

What Maven version ?
This seems a Maven issue since it seems to "eat" one "/" after the URI scheme.
Happens with the latest Maven ?

I'd also check your Java version.  When I had this issue on my Macbook, it was pointing to a legacy version of Java (version 6) that was installed for some BS app that required it, and wasn't using the Java 8 that I had installed manually.  Worth looking into.
