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

Mark,

>From initial inspection I would guess that the "build" directory does not
exist at build time for anthill because that is exactly the error you would
get from log4j.  If you are using cvs and if there is nothing in the build
directory then when anthill does the cvs checkout it would not get the
directory.  If this is the case you could add and commit a zero-length file
build/test.log to cvs.

If you modify the log4.confoguration file under the conf directory in
anthill you can get debug info to show in the app server log file.  This can
be very useful in troubleshooting.

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


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 [schemaexport]

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
