This maven plugin by default uses a fixed version of com4j (which is normally the latest when the plugin was released.) To use a newer version of com4j (for example perhaps you'd need to do this to pick up a bug fix), change your POM and add the following text:
<plugin> <groupId>org.jvnet.com4j</groupId> <artifactId>maven-com4j-plugin</artifactId> <executions> ... </executions> <dependencies> <dependency> <groupId>org.jvnet.com4j</groupId> <artifactId>tlbimp</artifactId> <version>20080105</version> <!-- version of your choice --> </dependency> </dependencies> </plugin>
