Ok, at least I found out where the old package name was coming from - pom.xml in osgi-int module: | <configuration> | <sourceDirectory>${basedir}/src/main</sourceDirectory> | <outputDirectory>${project.build.directory}/generated-sources/javacc/</outputDirectory> | <packageName>org.jboss.vfs.bundle</packageName> | </configuration> | I changed it to point to current javacc files package - org.jboss.osgi.plugins.metadata. But this doesn't change the duplicate error. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4035384#...
