Re: How to check Velocity version?
You would typically check for the presence of a class that has been
added since 1.5 - the typical getVersion() stuff hasn't been put yet in
Velocity.

Neat idea!
A manifest resource can be loaded using
<javaresource name="META-INF/MANIFEST.MF" classpath="${velocity.jar}"/>
but when I tried this it found one of the JVM manifests rather than
the velocity one.
I then tried <zipentry> instead, and this works:
<loadresource property="implementation.version">
<zipentry name="META-INF/MANIFEST.MF" archive="${velocity.jar}"/>
<filterchain>
<linecontains>
<contains value="Implementation-Version: "/>
</linecontains>
<tokenfilter>
<!-- Remove all but the revision number -->
<replaceregex pattern=".+: " replace=""/>
</tokenfilter>
</filterchain>
</loadresource>
<echo>${implementation.version}</echo>
However, this only applies if the script knows the name of the velocity jar.
If the jar is only available via a classpath, it gets a lot harder.
Maybe there should be an Ant task to look up / parse manifests...

Is there a way to check the manifest file?

That's what I ended up doing:
<available classpathref="anakia.classpath"
classname="org.apache.velocity.io.UnicodeInputStream"
property="velocity.version.15"/>
But it would be nice if there was a simpler way to do this.
