You could parse ${ant.version}.
ant.version=Apache Ant version 1.8.1 compiled on April 30 2010
<project>
<echoproperties prefix="ant"/>
</project>
> <antlib xmlns:c="ant:current">
> <ifver gt="1.8.0" eq="1.8.0">
> <componentdef name=".." .. />
A better solution would be to check for the availability of
the type you intend to use, like this:
<condition property="svn.type.found">
<and>
<typefound name="svn"/>
<typefound name="svnFileSet"/>
<typefound name="svnAdded"/><!-- etc -->
<typefound name="svnExists"/>
</and>
</condition>
