We are having the following problem generating javadocs using mvn javadoc:aggregate -DskipTest=true -P site,\!build-ui
>>> [ERROR] Exit code: 1 - javadoc: warning - Multiple sources of package comments found for package "org.osgi.framework" [ERROR] javadoc: warning - Multiple sources of package comments found for package "org.apache.commons.collections" [ERROR] javadoc: warning - Multiple sources of package comments found for package "org.acplt.oncrpc" [ERROR] javadoc: warning - Multiple sources of package comments found for package "org.apache.commons.beanutils" [ERROR] com/googlecode/concurrentlinkedhashmap/ConcurrentLinkedHashMap.class(com/googlecode/concurrentlinkedhashmap:ConcurrentLinkedHashMap.class): warning: Cannot find annotation method 'value()' in type 'javax.annotation.concurrent.GuardedBy': class file for javax.annotation.concurrent.GuardedBy not found [ERROR] com/googlecode/concurrentlinkedhashmap/ConcurrentLinkedHashMap.class(com/googlecode/concurrentlinkedhashmap:ConcurrentLinkedHashMap.class): warning: Cannot find annotation method 'value()' in type 'javax.annotation.concurrent.GuardedBy' <<< But I've had no luck at all adding <excludePackageNames> to our top-level pom.xml, e.g.. <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-javadoc-plugin</artifactId> <version>${maven-javadoc-plugin.version}</version> <configuration> <excludePackageNames>org.osgi.framework.*,com.googlecode.*</excludePackageNames> </configuration> <reportSets> <reportSet> <id>html</id> <reports> <report>javadoc</report> </reports> </reportSet> </reportSets> </plugin> Any troubleshooting tips would be appreciated.
