Is there a reason you're rebuilding your WAR three times on different Macs? > The code is pulled from my local git repo, and the supporting jars are from > a local Nexus repository.

Typically this means you expect the JAR will already be available at runtime, e.g. in your application server's provided JARs, so there's no point in bundling it into your WAR. Are you certain this is not just a case of having different application server versions installed, or someone manually updated the provided JARs on one of them? > The missing JAR doesn't seem to matter when the webapp runs (no > problems found so far).
