the import task in 1.8.x supports importing resources which can be
URLs. So maybe the main build file cannot be http based, but the meat
of the build file can. So maybe you can have a stub of a build file on
the file system ?
The scenario for this is that we frequently have to bootstrap our
deployment scheme on machines with not much more than a JVM[1], but
which can "call home". Being able to pull in the environment from the
mother ship means things are easier to script. I did not know the
import task now knows URL's, which could mean that the functionality I
need could be satisfied simply by downloading the remote build.xml file
to a temporary local file (with basedir set to current directory),
executed, and then deleted when the JVM exits.
[1] I'd also like an easy ant deployment scheme on such a machine, but
that is an issue for another day.
I just found that 1.8rc0 has been released, so to check if ant
already can do this I downloaded the svn source for HEAD [1], and had
a quick look at the source for org.apache.tools.ant.Main, where it
seems that all the logic for the build file is File-based, and a
quick look at the developer mailing list and the issues system did
not immediately reveal any discussion on this.
I'd really, really like this to be possible in ant 1.8, hence this
hurried mail, and I'd be happy to help.
What should I do now?

[1] The "ant bootstrap" process fails compiling optional taskdefs for
a plain svn extract. The installation documents does not mention how
to circumvent this.
to build the optional tasks, you need to download the dependencies
using ant -f fetch.xml ... (there are additional parameters). This can
put the libraries in lib/optional where the bootstrap process uses
them. I think currently only NetRexx is the only commercial dependency
which cannot be fetched that way, at least for my JDK 1.5 on Mac which
include s JMF and JAI in the extensions.
Thank you! I now have a compiling tree.
I'll have a closer look :)
