I don't think anyone has tried 0.23 in force because it (and the 2.0 branch) are still alpha. But I don't know a strong reason it wouldn't work other than you have to compile against 0.23 not the current supported version (1.0.4). And I think someone even added a Maven profile to select the 0.23 version as the dependency. It is not just a matter of changing the version in pom.xml since the artifacts split and changed names. Dig around in pom.xml to see what I mean. On Oct 29, 2012 6:07 PM, "Diego Ceccarelli" <[email protected]> wrote:
