I 'll be adding this to the README in light of the problem that Wolfgang detected: * Warning: The first `mvn` build of a day will download the latest SNAPSHOT dependencies of other droolsjbpm projects, unless you build all those droolsjbpm projects from source. Those SNAPSHOTS were build and deployed last night by hudson jobs. * If you 've pulled all changes (or cloned a repository) today, this is a good thing: it saves you from having to download and build all those other latest droolsjbpm projects from source. * If you haven't pulled all changes today, this is probably a bad thing: you 're probably not ready to deal with those new snapshots. In that case, add `-nsu` (= `--no-snapshot-updates`) to the `mvn` command to avoid downloading those snapshots: $ mvn clean install -DskipTests -nsu Wolfgang, You're using the latest droolsjbpm-parent SNAPSHOT (build by the droolsjbpm-build-bootstrap hudson job) with the non-latest drools repository code. I am afraid it's to late now to do -nsu, so if possible, I suggest just pulling all changes.
