I have a maven project with a snapshot dependency. How does maven know if the snapshot needs to be updated? Does it always update? Is it time based? A checksum based update? I know I can force an update but otherwise, how does it check?

thanks,
Jeff

    According to the docs, the default is that it will only update once a day. That is when the first build of the day is executed. You can override this behavior with the snapshot-policy element.

    • always – always check when Maven is started for newer versions of snapshots
    • never – never check for newer remote versions. Once off manual updates can be performed.
    • daily (default) – check on the first run of the day (local time)
    • interval:XXX – check every XXX minutes
