How to tell Maven to generate code when XSL has changed?

[Markus Karg]

I am using xml-maven-plugin to generate Java code from XML:

 

       <groupId>org.codehaus.mojo</groupId>

       <artifactId>xml-maven-plugin</artifactId>

       <version>1.0</version>

       <executions>

             <execution>

                    <phase>generate-sources</phase>

                    <goals>

                           <goal>transform</goal>

                    </goals>

             </execution>

       </executions>

 

This works well, but now I want that it automatically executes as soon
as the used transformation XSLT file was modified. So how can I tell
maven that it shall do generate-sources as soon as a particular file was
touched?

 

Thanks!
