Maven - How do I get the Castor plugin to trigger in the generate-sources phase?

Question

I am mavenizing an ant project. One module includes XSD files that are used to generate source files using Castor. I have everything working if I run:

mvn castor:generate package

However I am not able to get it to run the generate goal for my plugin without specifying it on the command line. My plugin xml section is as follows:

<plugin>
      <groupId>org.codehaus.mojo</groupId>
      <artifactId>castor-maven-plugin</artifactId>
      <version>1.0</version>
      <configuration>
      </configuration>
      <executions>
        <execution>
          <phase>generate-sources</phase>
          <goals>
            <goal>generate</goal>
          </goals>
        </execution>
      </executions>
</plugin>

I have tried a number of phase entries without any luck. Any idea what I am doing wrong here? I have tested this in Windows XP and Linux, using Maven 2 and 3. I have tried it with version 1.0 (which I must use) and 2.0 of the castor-maven-plugin.

Thanks Tim

The castor:generate goal is bound by default to the lifecycle phase generate-sources so you don't even have to bind it explicitly unless you want to bind it to another phase of course.

Assuming your *.xsd are in the default directory src/main/castor, the following would thus be enough:

  <plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>castor-maven-plugin</artifactId>
    <version>1.0</version>
    <configuration>
      <!--schema>src/main/castor/schema.xsd</schema-->
    </configuration>
    <executions>
      <execution>
        <goals>
          <goal>generate</goal>
        </goals>
      </execution>
    </executions>
  </plugin>

And assuming you have a src/main/castor/castorbuilder.properties file, here is the output when invoking a phase posterior to the generate-sources phase:

$ mvn package [INFO] Scanning for projects...

In other words, the version 1.0 of the plugin gets triggered as expected (version 2.0 works too). Tested with Maven 3.0.

If it doesn't for you, please provide a project allowing to reproduce and mention the goal you invoking.
