Ant troubleshooting

If you get an error like this:

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

when using ant then it may well be because you don’t have the ant-optional package installed (if you are using Ubuntu or similar.) You can install this with apt-get by typing:

apt-get install ant-optional

as root.
