Comment 1 Benjamin Reed CLA 2011-04-21 12:34:55 EDT 
Version is the latest one in the public eclipse repository, it wasn't in the "version" pull-down:

  Maven Integration for Eclipse (Required)	0.12.1.20110112-1712
  Maven Integration for WTP (Optional)	0.11.1.20101108-1810
Comment 2 Igor Fedorenko CLA 2011-04-21 12:47:05 EDT 
m2e/wtp bugs should be reported to https://issues.sonatype.org/browse/MECLIPSEWTP
Comment 3 Benjamin Reed CLA 2011-04-21 13:39:25 EDT 
Ah, OK.  I originally went to https://issues.sonatype.org/browse/MNGECLIPSE and it said that it was read-only.  Didn't occur to me that sub-projects are not read-only, but the main one one is.  Kinda confusing.
