OK, the problem is that I used cobertura plugin as <build> <pluginManagement> <plugins> <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>cobertura-maven-plugin</artifactId> <version>2.5.1</version> <configuration> <formats> <format>xml</format> <format>html</format> </formats> </configuration> </plugin> </plugins> </pluginManagement>
Instead it should be as <build> <plugins> <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>cobertura-maven-plugin</artifactId> <version>2.5.1</version> <configuration> <formats> <format>xml</format> <format>html</format> </formats> <check/> </configuration> <executions> <execution> <phase>clean</phase> <goals> <goal>cobertura</goal> </goals> </execution> </executions> </plugin> </build> <reporting> <plugins> <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>cobertura-maven-plugin</artifactId> <version>2.5.1</version> </plugin> </plugins> </reporting> After this I point Jenkins Cobertura plugin to *core/target/site/cobertura/ coverage.xml*
