[Anthill] Hibernate SchemaExport task fails under Anthill...

[Mark Derricutt]

Hi all, we seem to have hit an odd problem with Anthill,

We've recently started using Hibernate in some of our applications and 
are noticing that the schema-export task fails under Anthill.

It works fine running Ant directly on every machine in the office, but 
on two different installs of Anthill, it fails:

export-schema:
     [echo] Exporting DB schema to db/schema-v0.1.4.sql

The ant script includes:

    <!-- Exports DB schema to a file -->
    <target name="export-schema" depends="generate-hibernate"
              description="Exports DB schema to a file">

        <!-- Teach Ant how to use Hibernate's schema generation tool -->
        <taskdef name="schemaexport"
            classname="net.sf.hibernate.tool.hbm2ddl.SchemaExportTask"
            classpathref="classpath">
            <classpath path="${build.classes}"/>
        </taskdef>

        <echo message="Exporting DB schema to ${db.dir}/schema-${version}.sql"/>
        <schemaexport properties="${build.classes}/hibernate.properties"
                quiet="yes" text="yes" drop="no" output="${db.dir}/schema-${version}.sql" >
            <fileset dir="${build.classes}">
                <include name="**/*.hbm.xml"/>
            </fileset>
        </schemaexport>
    </target>

Has anyone seen this at all?  I was thinking it might be related to class loaders, or the way Anthill calls ant...

Thanks in advance,
Mark
