[m2] using hibernate plugin

["Rico (privat)" <ri...@gmx.de>]

Hi,

I downloaded the soures of the actual hibernate 3 plugins from

http://svn.codehaus.org/trunk/mojo/mojo-sandbox/hibernate3-maven-plugin/?root=mojo

1. Compiled that sources: mvn compile
2. Make a package: mvn package
3. Install it on my local repository: mvn install -DupdateReleaseInfo=true

All was running fine. But if I want to used it in my own project it 
fails with:

Before that I prepared my project pom.xml as described on documentation 
to maven-hibernate3-plugin:

  <build>
    <extensions>
      <extension>
          <groupId>org.firebirdsql</groupId>
          <artifactId>jaybird</artifactId>
          <version>1.5.6</version>
      </extension>
    </extensions>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-hibernate3-plugin</artifactId>
                <configuration>
                    <config>/src/main/resources/hibernate.cfg.xml</config>
                </configuration>
            </plugin>
        </plugins>
    </build>

The command line was following:

mvn hibernate3:hbm2dll

After getting that error first time I found a short message on

http://www.hiberforum.org/2005/09/#000009

which gives a solution to find inofficial plugins also with:

mvn org.codehaus.mojo:hibernate3-maven-plugin:hbm2dll

but the error keep the same. The plugin couldn't find or some thing else.

Any help or ideas?

Thanks in forward
Rico
