Subject Re: storing optional (ftp) task jar dependency under my project instead of under /ant/lib
Date Tue, 12 Jul 2005 18:11:46 GMT
Ok, in that case alt.3 is not very attractive afterall. I don't know
if it is just me but I prefer do embed this type of behaviour in the
build.xml and project itself.

I have had similar problems with system environment variables in
particular charset encodings which need to be set outside of the
build.xml. Instead of just executing the build.xml this causes me to
have a shellscript to set the environment variables and execute the
build.xml

What I could do in this particular case is provide an install
mechanism (a target in the build.xml perhaps) for the ftp-task which
copies the commons-net-1.1.0.jar from the projects lib directory into
$HOME\.ant\lib. That way it would be fairly straightforward to use.
