Can you try building again? It works for me.
I'm able to download jsftemplating artifacts.
This is not related to .m2 directory. The build error indicates that
it's not able to find jsftemplating artifacts.
It's there in Nexus but jsftemplate artifact are deployed to maven 1
repository so there are no pom files:
http://download.java.net/maven/1/com.sun.jsftemplating/jars/
thus download time may be slow.
