I'm trying to build a standalone grails (v.2.5.0) app using the grails standalone app runner plug-in (v.1.3). With run-app and run-war everything works fine and I can also deploy the WAR file to a tomcat 7 instance without any issues. However, if I build a standalone JAR with grails build-standalone I cannot start the JAR due to the following ClassNotFoundException:

To show that this problem is reproducible I have prepared a minimal example on github:
https://github.com/mlist/grails-standalone-search-bug
I created a bug report at: https://jira.grails.org/browse/GPSTANDALONE-22
I already tried switching from default tomcat 8 to tomcat 7 and jetty (same result). I also tried java 7 and java 8, both with the same result.
Here is the answer Burt Beckwith gave on my bug report:
Sorry to do this, but I can't spend any time working on this issue. You shouldn't be using the searchable plugin - it only works with Hibernate 3, and it doesn't scale because it uses a local file-based index. It's based on Compass (http://sourceforge.net/projects/compass/files/compass/), which was last updated in 2009. ElasticSearch is a much better option - see http://thedudeabides.com/articles/the_future_of_compass/
