This is pretty incomplete, a lot of the Ant's own jars are missing.

requires either ant-nodeps.jar for using JDK 1.4+ regexp or
ant-apache-oro.jar (given that you have ORO in ANT_HOME/lib).

this is in ant-nodeps.jar which you don't have.

The Ant distribution only contains Ant's own classes, they are not the
dependencies required.  You may have thought ant-apache-oro.jar and
jakarta-oro-2.0.8.jar were the same, but they aren't.
ant-apache-oro.jar contains the classes that require ORO, you need
both of them in ANT_HOME/lib to make things work.

There is a build file called fetch.xml in Ant's svn repo[1] (it is
also part of the source distribution, it could even be part of the
binary dist, not sure) that will use the Maven Ant tasks to collect
all available optional dependencies.

Ant does have some optional dependencies on proprietary third party
jars that cannot be provided at all.  I wouldn't expect any of the
projects you build in buildbot to make use of the related tasks,

I think so.  We used to have nightly builds on vmbuild, but I don't
think they are available anymore.

Many thanks
