Uncheck "Install automatically" and an ANT_HOME field should appear. Try setting the installation there if you have not tried it already.
Hi build, what version of Java are you using?
This does not seem like an issue with the Ant Plugin though, but an issue with your current installation since you cannot even run Ant from the command line, can you?
