Hi Nicola, I was able to fix this issue adding the following line into the munge maven plugin:
<mungedDirectory>${project.build.directory}/munged</mungedDirectory> Now it is: <plugin> <groupId>org.sonatype.plugins</groupId> <artifactId>munge-maven-plugin</artifactId> <version>1.0</version> <executions> <execution> <id>munge</id> <phase>generate-sources</phase> <goals> <goal>munge</goal> </goals> <configuration> <mungedDirectory>${project.build.directory}/munged</mungedDirectory> <symbols>${munge.symbols}</symbols> </configuration> </execution> </executions> </plugin> I hope that this will help you. Regards, Alessandro
