Hi Everyone,
Would those that are able to configure their GAE project to bundle their classes into a single JAR please kindly share their configuration steps as an answer to the stackoverflow question http://stackoverflow.com/questions/9397101/configure-eclipse-to-pre-bundle-app-engine-classes-into-a-single-jar-for-faster ? This is the same question that Richard had linked earlier in this discussion thread. As the asker of the question, I would love to finally see some definitive/canonical answer that could be helpful for a broad audience. Thank You and Best Regards, Ibrahim On Saturday, June 23, 2012 7:22:34 AM UTC+2, Richard Watson wrote: > > Hi Will, > > I also tried bundling (most [1]) jars into one but it didn't seem to move > the needle at all, once classes were jarred.
