I thought I would give some feedback, it seems that I made two mistakes...
1) I typed the incorrect version number, so this was why it could not find
the explicitly named jar file.
2) even after fixing the jar name this syntax did not work...
<taskdef resource="net/sf/antcontrib/antlib.xml">
<classpath>
<pathelement location="/lib/ant/ant-contrib-1.0b3.jar"/>
</classpath>
</taskdef>
(yes I did correct the jar name by this point!)
but this did work...
<taskdef resource="net/sf/antcontrib/antlib.xml">
<classpath>
<fileset dir="lib/ant" includes="*.jar"/>
</classpath>
</taskdef>
Does anyone know what was wrong with the first one?
Cheers,
Rob.
