This error occurs:
/tmp/build2.xml:22: restrict doesn't support the nested "type" element.


<project name="main">

  <macrodef name="assertDirs" backtrace="false">
    <element name="rc" implicit="true" />
    <sequential>
      <difference id="assertDirs.missing">
        <rc />
        <restrict>
          <rc />
          <type type="dir" />
        </restrict>
      </difference>

      <fail message="Missing ${toString:assertDirs.missing}">
        <condition>
          <resourcecount when="gt" count="0" refid="assertDirs.missing" />
        </condition>
      </fail>

Here's a cool example if I do say so myself:

<project>

  <macrodef name="assertDirs" backtrace="false">
    <element name="rc" implicit="true" />
    <sequential>
      <difference id="assertDirs.missing">
        <rc />
        <restrict>
          <rc />
          <type type="dir" />
        </restrict>
      </difference>

      <fail message="Missing ${toString:assertDirs.missing}">
        <condition>
          <resourcecount when="gt" count="0" refid="assertDirs.missing" />
        </condition>
      </fail>
    </sequential>
  </macrodef>

  <assertDirs>
    <filelist id="dirs" dir="${basedir}" files="bin,chat,client" />
  </assertDirs>
</project>

Wrap that macrodef up and take it wherever you like!

HTH,
Matt
