Troubleshooting Compilation

If you are attempting to build and you see the following error:

No supported regular expression matcher found: java.lang.ClassNotFoundException: org.apache.tools.ant.util.regexp.Jdk14RegexpRegexp

Or something similar, you need to install additional optional ant jars. On Ubuntu, try

apt-get install ant-optional
