I can't seem to find any documentation on this, so maybe you can just tell me. What is the exact rule for when Maven will check for a newer snapshot from a remote repo (when you're not using -U) ?
It seems to be something like: 1. If you don't already have the snapshot it will check. 2. If your latest snapshot is older than 24 hours it will check. But that's just me kinda guessing. I don't know what the exact rule is, but I would like to. Phillip
