Hi, Could you give us more information with the debug mode : mvn findbugs:findbugs -X
You also can try this, it works for me (except http://jira.codehaus.org/browse/MOJO-563). <build> <plugins> ... <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>findbugs-maven-plugin</artifactId> <version>1.0-SNAPSHOT</version> <executions> <execution> <id>findbugs</id> <phase>validate</phase> <goals> <goal>findbugs</goal> </goals> </execution> </executions> <configuration> <xmlOutput>true</xmlOutput> </configuration> </plugin> </plugins> </build> HTH, Rémy
