Hello:

I am trying to get the SchemaExportTask to generate DDL for me. However, I believe there is something wrong with my Ant task. Your kind assistance is requested.


Please find below my build.xml for ANT and my hibernate.cfg.xml
I am trying to run the task schemaExportTask.

When I run --> ant schemaexport -verbose
I get the following:

Apache Ant version 1.7.0 compiled on December 13 2006
Buildfile: build.xml

I am sure you folks who know what you are doing will see my mistake very quickly.

Thanks for your assistance.

Full stack trace of any exception that occurs:

Name and version of the database you are using:


Debug level Hibernate log excerpt:

I re-ran with build.xml as follows:



my hibernate.cfg.xml contains:




error i get is:
BUILD FAILED
C:\KBD\dev\hibernate\helloworld\WORKDIR\build.xml:73: Schema text failed: resource: ./build/hello/Message.hbm.xml not found

if I change hibernate.cfg.xml to be:



error i get is:
BUILD FAILED
C:\KBD\dev\hibernate\helloworld\WORKDIR\build.xml:73: Schema text failed: resource: build/hello/Message.hbm.xml not found

so in my simple mind it is either something with the resouce mapping or the fileset on the task in build.xml.
I do not see it.

assistance requested.

kd

OK I spent a long day. Tinkering with various small changes to the build.xml file
I made changes to the "project.classpath" and to the "fileset" on the schemaexport task.

No progress.

The only thing I know for sure is that the schemaexport task is looking for the file specified in <mapping resource="hello/Message.hbm.xml"/> in hibernate.cfg.xml.
But where it is looking for it is beyond me.

I think the error is something very simple with the path.

kd

I am also facing similar problems.. Using hibernate3.jar from hibernate-tools running with jdk1.5 and tomcat 6.0.16.

I get an exception like this..

D:\Application\build.xml:111: Schema text failed: Resource: xml/hbm/User.hbm.xml not found
at org.hibernate.tool.hbm2ddl.SchemaExportTask.execute(SchemaExportTask.java:146)
at org.apache.tools.ant.UnknownElement.execute(UnknownElement.java:288

My build file has the following properties set.. I use similar properties for hbm2java ant task and they seem to work fine.

<taskdef name="schemaexport"
classname="org.hibernate.tool.hbm2ddl.SchemaExportTask"
classpathref="project.classpath"/>

<schemaexport config="${project.src}/hibernate.cfg.xml"
quiet="no"
text="yes"
drop="no"
delimiter=";">
<fileset dir="${hibernate.hbm}">
<include name="**/*.hbm.xml"/>
</fileset>
</schemaexport>


If some one found a workaround to this it would be great..

Hi,

I have the same problem with hibernate 3:
http://forum.hibernate.org/viewtopic.php?p=2399687

Do you find a solution?

Thx,
