How can I keep an import statement from resetting a path id?

[Eric Wood]

Is there a way to conditonally set a path id for a classpath when I'm
importing a file?

 I have two files that I import from a build.xml. The first file sets a
path id for my classpath and the second one resets it when the file is
imported even though the path id is set in a target with an <if>
conditional statement around it.


Here is the xml statements from the second ant file that is imported

    <target
      name="init"
      description="Used to configure for a build">


        <if>
          <isreference refid="classpath.build" />
            <then>  <!-- do nothing -->
            </then>
            <else>
                <echo>classpath not explicitly set by module. Using
classpath.base from ancestor</echo>
                <path id="classpath.build">
                    <path refid="classpath.base" />
                </path>
            </else>
        </if>

  </target>

Thanks in advance.
