### Examples

Store the current Ant version in the property `antversion`.

    <antversion property="antversion"/>

Store the Ant version in the property `antversion` if the current Ant version is 1.6.0 or higher. Otherwise the property remains unset.

    <antversion property="antversion" atleast="1.6"/>

Set the property `ant-is-exact-7` if Ant 1.7.0 is running. Neither 1.6.5 nor 1.7.1 would match.

    <antversion property="ant-is-exact-7" exactly="1.7.0"/>

Set `Ant17isOnline` if Ant 1.7.0 is running and can get a non-error-response from the Ant homepage.

    <condition property="Ant17isOnline">
      <and>
        <antversion exactly="1.7.0"/>
        <http url="http://ant.apache.org"/>
      </and>
    </condition>
