Hibernate is not compiling relates to KNL-945 looks like most errors around getSession (used like 20 times) but maybe more.
[ERROR] /var/lib/jenkins/jobs/evaluation trunk build/workspace/sakai-evaluation-impl/src/java/org/sakaiproject/evaluation/dao/EvaluationDaoImpl.java:[105,13] cannot find symbol
[ERROR] symbol: method getSession()
Possible suggestion for this one http://stackoverflow.com/a/10422140/3708872
Upgrade to Hibernate 4
Upgrade to Hibernate 4.3.x
