I'd like to include a lib directory in my classpath. The problem is I
don't know where the lib directory will be. It will either be ../../lib
or ../lib, relative to my current path. Is there a way to set a property
to whichever of those two exists?

=20

For example:

=20

/lib

/foo/build.xml

property would be set to ../lib

=20

=20

=20

/lib

/foo/bar/build.xml

=20

property would be set to ../../lib

=20

Here's my attempt, but it doesn't work because properties set inside
subant tasks aren't set when subant exits.

=20

      <target name=3D"findcommon">

            <echo>Finding common directory...</echo>

            <available file=3D"../../lib" type=3D"dir" =
property=3D"two_up" />

            <antcall target=3D"two" />

            <antcall target=3D"one" />

            <echo>Path to lib set to: ${path_to_lib}</echo>

      </target>

     =20

      <target name=3D"two" if=3D"two_up">

            <echo>Two folders up...</echo>

            <property name=3D"path_to_lib" location=3D"../../lib"/>

      </target>

     =20

      <target name=3D"one" unless=3D"two_up">

            <echo>One folder up...</echo>

            <property name=3D" path_to_lib" location=3D"../lib"/>

      </target-->

Thanks in advance for your help!
