In my build.xml I had the following target so as to create a schema in a specific sql file and it worked.


<taskdef name="schemaexport"
classname="org.hibernate.tool.hbm2ddl.SchemaExportTask"
classpathref="schema.classpath"/>
<target name="schema">
<schemaexport
quiet="no" text="true" drop="no" delimiter=";"
output="schema-export.sql"
config="build/WEB-INF/classes/hibernate.cfg.xml"> </schemaexport>
</target>

Because I am using Hibernate 3 I decided to use the hibernate tools to create the schema so I created the following target:

<taskdef name="schemaexportHibernate3task" classname="org.hibernate.tool.ant.HibernateToolTask"
classpathref="schema.classpath"/
<target name="schemaExportHibernate3">
<hibernatetool destdir=".">
<configuration configurationfile="build/WEB-INF/classes/hibernate.cfg.xml"/>
<hbm2ddl outputfilename="schema-export.ddl" export="false"/>
</hibernatetool>
</target>

However this target is not working and says that it cannot find my *.hbm.xml files. Moreover why do I need a destdir in hibernatetool since I only want to fill the schema-export.ddl and not to generate any other file?

Any clue?

1) what is so bad about wanting a destdir ?

2) did you put your hbm.xml on the classpath so the resources you most likely specified in your hibernate.cfg.xml can be found ?

3) the tools forum is a better place for these kind of questions ;)

It is not bad, I just do not understand its use?What is it going to be created there?




Yes I did that is why I enclose the previous target that was working to show that the classpath is ok.

schema-export.sql for one.

You should put your hibernate project related classpaths inside the hibernatetool/configuration task - not in the taskdef.

btw. afaik it should only complain about it if its actually needed ....which it is in this case since you put schema-export.sql there

Indeed the problem was that I did not include the classpath in the hibernatetool. As far as the destdir is concerned I was asking because I thought that it was enough the outputfilename="schema-export.ddl" to define the location of the ddl, but yes destdir is mandatory.

Thank you very much for your answers.
