Hi Uli,
Please try to use the xdoclet maven plugin from codehaus.
I am not sure if it´s gonna work. Just give a shot and let me know the results.
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>xdoclet-maven-plugin</artifactId>
<version>1.0-alpha-2</version>
...
Regards,
Dário

Subject: Maven 2 xdoclet Null Pointer Exception
Hello,
i'm new to m2 and i want to move a little project with xdoclet for
hibernate mapping from ant to maven 2.
I'm not sure if i'm on the right way.. I've added to the generated pom
following :
<build>
<plugins>
<plugin>
<groupId>xdoclet</groupId>
<artifactId>maven-xdoclet-plugin</artifactId>
<version>1.2</version>
<executions>
<execution>
<phase>generate-sources</phase>
<goals>
<goal>xdoclet</goal>
</goals>
<configuration>
<tasks>
<!-- here i think must be the
hibernatedoclet : -->
</tasks>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
Question 1: With this i get following error in a mvn compile:
[DEBUG] maven-resources-plugin: resolved to version 2.0 from repository
central
[DEBUG] Retrieving parent-POM from the repository for project:
