Easier way to declare externally-written tasks in build script

           Summary: Easier way to declare externally-written tasks in build
                    script
           Product: Ant
           Version: 1.6.0
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Enhancement
          Priority: Other
         Component: Core

        ReportedBy: kk@kohsuke.org


It is easy to write an Ant task, but the amount of build script you need to
write to use it can be made shorter.

Today, it takes the following lines of build scripts to declare a new task:

<taskdef task="taskName" classname="fully.qualified.class.Name">
  <classpath>...</classpath>
</taskdef>

Alternatively I can use property files, but it still requires a fully qualified
name of the property file.

I wonder if Ant can look for a property file in a known location (such as
/META-INF/services/org.apache.tools.ant.Task); together with Class-Path manifest
attribute, this would allow my users to just say something like:

<taskdef jar="lib/foobar.jar"/>

... which is much shorter and concise.
