Latest Clojure master doesn't build

Defect Major Closed Declined Unassigned Edward Z. Yang Thu, 14 Jun 2012 09:25:45 -0500 Fri, 20 Jul 2012 16:49:29 -0500 Fri, 20 Jul 2012 16:49:29 -0500 Release 1.5 0 1 <p>What command did you use?</p> <p>From the error message, my guess is that you ran "ant" without first running "./antsetup.sh". If that is the case, run "./antsetup.sh" first. This is a new step added to readme.txt on May 7, 2012, because of the jsr166y.ForkJoinPool class used within Clojure to implement the new parallel reducers feature.</p> <p>Yep, that's exactly it. Can we setup ant to warn people if antsetup.sh hasn't been run?</p> <p>I don't know. I suspect if it could be done and it were a straightforward modification, a patch for that would be accepted. I suspect those who created antsetup.sh would have simply modified the build.xml file for ant, and not created antsetup.sh at all, if it were easy to do so.</p> <p>It can be done with just the build.xml but requires the <a href="http://maven.apache.org/ant-tasks/index.html">Maven Ant Tasks jar</a> to be in the local ant's classpath, which is not ideal.</p> <p>Because a local maven install is anyway required by antsetup.sh, IMHO it would be best to remove the ant build all together and stick with solely with a maven build, no?</p> <p>I can't find the email right now, but I believe in the past Rich Hickey has expressed a preference for continuing to have a way to build Clojure using ant.</p> <p>Ant is there for the convenience of various dinosaurs, myself included. In general you should use the maven build, as that is what the CI and release process do.</p> Global Rank
