If you are using Maven the current dev build version you will want for your Jena dependency will be 2.10.1-SNAPSHOT
If you are using multiple Jena components you should use the latest SNAPSHOT across all your Jena dependencies as otherwise you will run into issues with conflicting versions of Jena modules on the class path. Note - There may be a 24 hour or so delay between when a fix is committed and when it is available in a development snapshot because snapshots are only deployed on a nightly basis. You can see when the last snapshot was built and deployed and what changes it contained at https://builds.apache.org/job/Jena__Development_Deploy/ Rob On 3/19/13 3:59 PM, "Dave Reynolds" <[email protected]> wrote: >Yes you need to update your copy of Jena. > >As it says on: > > http://jena.apache.org/download/index.html > >Development builds are available from: > > >https://repository.apache.org/content/repositories/snapshots/org/apache/je >na/ > >Dave > >On 19/03/13 22:42, Léonard PETNGA wrote: >> Hi Andy, >> I understand from your email below that the issues I mentioned in my >>email >> have been fixed.
