release-version.sh: try again with -U as needed

ctrueden · ctrueden · commit d95ccbd81c8a · 2022-02-20T13:13:41.000-06:00
It's nice if, when failing to extract the version due to dependencies not being present in the remote repository, we first try again using -U before giving up. Otherwise, we may end up with the unfortunate error: Failure to find <artifact> in https://maven.scijava.org/content/groups/public was cached in the local repository, resolution will not be reattempted until the update interval of scijava.public has elapsed or updates are forced If the artifact has been successfully deployed after the local system last checked for it, but 24 hours has not yet elapsed, the -U flag will force a new check to find the artifact, and the release can continue.
