-----------------------------------------------------------------
Here the patch. The javacc task is a little bit complicated (needed some help
from blogs,...) because javacc.jar does not contain the ant task. The task is
shipped with ANT and ANT expects a attribute called "javacchome", that must
point to the home folder of an extracted javacc distribution (although it only
uses the JAR). <javacc/> looks inside this dir for bin/lib and inside this dir
for a file named javacc.jar (without version).
So we cannot use ivy:cachepath and ivy:retrieve is too unflexible (it allows to
setup directory layout, but filename always contains version).
The trick here is a "handwritten" resolve/rewrite:
- get ivy:cachefileset for javacc-5.0.jar artifact
- create a "fake" release folder in ${build.dir} and then copy the cachefileset
into it with a <mergemapper to="javacc.jar"/>.
- the javacc.home dir is then located in ${build.dir} and nuked on ant clean.
This patch also cleans up javacc at all. We only use javacc in the queryparser
module so I moved all ant logic there. I also removed some unused tasks and
properties.
I will commit soon.
