Description

Here's the command I ran (on a fresh morning, because our update policy is daily and our SNAPSHOTs are deployed by Hudson at night, with maven 3.0.3):

$ mvn -nsu clean install -DskipTests

Despite that I added "nsu" (also known as "-no-snapshot-updates"), it downloaded snapshots.

This is a pretty bad thing, because if I hadn't pulled in days (and just wanted to test my local changes before merging in remote changes),
this would have broke my build, for example:

• because the parent pom in downloaded SNAPSHOT had a dependency removed which my local pom was still using (because I hadn't pulled the changes yet)
• because the downloaded knowledge-api changed a non-released method signature (and I hadn't pulled the changes to deal with that yet).
