Patience! We're nearly there... ;-) > I tried grabbing a copy of the trunk but ended up with a different error. Did you follow the instructions for compiling/building D2RQ from source? https://github.com/d2rq/d2rq#readme If so, then can you please provide the following details: 1. What OS is this on? 2. What JVM and what version of Java are you using? (run "java -version") 3. Which commands did you execute to build from source? 4. What *exactly* is the command that you executed when you got the error? (We've made some changes to the startup scripts in the last couple of days to make them work on more platforms, so it's possible that there's some regression.) > And it seems d2r-query is missing. Not sure what you mean? Both d2r-query and d2r-query.bat are certainly there in the master branch.
