When org.slf4j.helpsers.MessageFormatter is used, the Maven plugin fails with ClassNotFoundExceptions if Maven 3.3 is used. Builds seem to work fine with Maven 3.2. There is an upstream bug at https://issues.apache.org/jira/browse/MNG-5787, but no resolution yet it seems.

The workaround mentioned in the issue does not work. You need to downgrade to Maven 3.2.5.

Maven 3.3.9 fixes this issue, meaning you can build Spoofax with Maven 3.2.5 and 3.3.9.

Just to add to this, the pre built eclipse distro for linux-x64 on http://www.metaborg.org/en/latest/source/release/note/2.0.0-beta1.html has an the old maven version embedded, so this issue is triggered. I was able to work around by pointing to a newer maven install (3.3.9) in eclipse preferences, under maven installs.
