Can anyone help me figure out what this means? I'm using maven 2.0.4
(but I tried maven-2.1-SNAPSHOT with the same results). I'm doing a
reactor build and although my build works perfectly fine when I go to
each submodule and invoke "mvn install", if I try to do this from the
top level pom directory, I get this error: I'm posting here because
I've had no luck on the users@maven.apache.org list. Thanks. -- eric
