Recovering from a bad release or a vetoed release
Recovering from a bad release actually isn't that difficult. You'll have to delete the bad tag in SVN and rollback the version numbers in all of our pom.xml files.
Delete the tag in svn
$ svn del https://svn.apache.org/repos/asf/openjpa/tags/1.2.0 -m "Rollback release"
Rollback version numbers
If you have perl installed you can do this in a single command for example to rollback from 1.2.1-SNAPSHOT to 1.2.0-SNAPSHOT
$ perl -pi -e "s;<version>1.2.1-SNAPSHOT</version>;<version>1.2.0-SNAPSHOT</version>;g" \
pom.xml */pom.xml */*/pom.xml
If you do not have perl installed you can use a similar tool to edit multiple files or edit them all by hand.
