import file from jar (or classpath)
Hi,
I know there's not currently a way to do this, but I think it would be
very helpful to be able to use the import task to import a file from a
jar.
This way, when I have a handful of projects, all with common targets, I
can put the common.xml build file in a jar and have each project depend
on that jar.
Combined with something like ivy, I think this would be a pretty good
way to share common targets among multiple projects that may not have
anything to do with each other.
Any thoughts?
Any way to do this now?

seems reasonable..classpath loading is so common it should be a base
type independent of most others.

After writing the patch for the import task, I also noticed that DefBase
includes most of the methods needed to load a classpath resource,
however, it extends AntlibDefinition. I think it would be a useful
refactoring to create a ResourceBase that other classes including
AntLibDefinition can subclass when the task needs to load a classpath
resource.

this has been discussed for a while, and its something I'd like to do
for Ant1.8...I've started making some of the changes in uncommitted
code, primarily working on the base interfaces.
The goal would be to let you import any suitable resource, be it
something on a classpath, remote URL, etc.
Before we can do that, bear in mind that when you import a file, it has
a location, that can be used for relative locations. If I import a bit
of xml from org,example.somewhere, that file should have the right to
import ../something/else.xml. Same for URL-based imports. The code you
import should not have to know how you found it, to pull in relative files.
What I'm planning for this is a new interface for some resources to
support, a RelativeResourceFactory. Resources that implement it can
create new relative resources by taking in the current location and a
relative path. We'd retrofit this to file, URL and classpath resources,
all of which could then be a resource source.

Which up and coming Ant release will this be included? I have a real
need for this as I have many Ant XML files that would be better suited
to live in a Jar and be Ivy-tized ;)

This is really good progress. Is there any technical issue to enable remote
ant build file by http or whatever?
The goal is to enable to start writting a build just referencing a remote
build file (may be cached in a temp that would be used if remote
unavailable) and to share build among several project easily...

I added a bug to the bug database and attached a patch that adds the
same classpath functionality as taskdef to the import task.

Re: import file from jar (or classpath)

In a previous post I suggest this:
I wish Ant import would support URL + jar like that :
<project ...>
<import url="http://repo/build.jar!common-build.xml"/>
</project>
As ivy became a sub project, it would make sense to have a closer
integration like :
<project ...>
<import url="ivy://settings.xml:org/module/artifact@MyResolver" />
<!--
would locate the settings.xml file and seek a build-common.xml file using
MyResolver resolver.
-->
</project>
we could imagine deeper integration :
<project ...>
<import url="ivy://settings.xml:org/module/artifact@MyResolver"
ivyFile="${basedir]/ivy.xml"/>
<!--
configure ivy / read the ivy file
would map each ivy configuration to a path ( path could use a lazy resolve
proxy: resolve only when it get used)
would import resolved artifcat as an ant build file
-->
</project>
