I must be using the wrong archive -- in the 3.5.0 packages, I only see an earlier Mondrian jar, and, while I see subsequent 3.5.x releases in svn, I do not see any src archive in the download area or repo that contains the updated mondrian jar. > find . -name *ondrian*.jar ./jasperserver-repo/mondrian/mondrian/3.0.4.11371-Jaspersoft/mondrian-3.0.4.11371-Jaspersoft.jar ./jasperserver-repo/mondrian/mondrian/3.0.4.11371/mondrian-3.0.4.11371.jar which builds, but I am not able to find a jasperserver-repo to build later versions of jasperserver, e.g. the 3.5.1
