Easy. Run the following maven command *outside* of any maven project. The
result will be the same:
{code:java}
mvn dependency:copy -Dartifact=org.postgresql:postgresql:LATEST:jar
-Dproject.basedir=. -DoutputDirectory=xxx -DoverWrite=false {code}

I can't find a way to reproduce the problem. Do you have the command you were
using and a simple project ?
