Hi, i cannot find information about this problem.

I try to generate schema-export with maven-hibernate3 plugin.

I get this exception every time.

I use command:
$ mvn clean compile resources:resources hibernate3:schema-export

The error always occurs at the first hbm.xml it tries to map, so I can shortcut the logging to the relevant parts.

There is no duplicate import, the error happens at this hbm-file, but as I remove it, the error occurs at another hbm-file.

If I remove the offending collection-properties, the error exception at classlevel dupication comes up.

For information, my hibernate.cfg.xml (partly)

<?xml version='1.0' encoding='utf-8'?>

(there are more mapping files, but this is the one that gives the error, at this moment)

Thanks in advance for helping, I am struggling three days with this now, loosing really time I do not have
