PROBLEM
The Cobertura Maven Plugin doesn’t respect the exclusion configuration. For example, if you have the following pom.xml, the exclusion configuration does absolutely nothing when you execute mvn site.
<project ...="">
...
<reporting>
<plugins>
<plugin>
<groupid>org.codehaus.mojo</groupid>
<artifactid>cobertura-maven-plugin</artifactid>
<version>2.5.2</version>
<configuration>
<instrumentation>
<excludes>
<exclude>**/wsdl2java/**</exclude>
</excludes>
</instrumentation>
<formats>
<format>html</format>
<format>xml</format>
</formats>
<check>
</check></configuration>
</plugin>
</plugins>
</reporting>
</project>
SOLUTION
To fix this, you will need to define the Cobertura Maven Plugin under both <build> and <reporting>.
<project ...="">
...
<build>
<plugins>
<plugin>
<groupid>org.codehaus.mojo</groupid>
<artifactid>cobertura-maven-plugin</artifactid>
<version>2.5.2</version>
<configuration>
<instrumentation>
<excludes>
<exclude>**/wsdl2java/**</exclude>
</excludes>
</instrumentation>
<formats>
<format>html</format>
<format>xml</format>
</formats>
<check>
</check></configuration>
</plugin>
</plugins>
</build>
<reporting>
<plugins>
<plugin>
<groupid>org.codehaus.mojo</groupid>
<artifactid>cobertura-maven-plugin</artifactid>
<version>2.5.2</version>
<configuration>
<instrumentation>
<excludes>
<exclude>**/wsdl2java/**</exclude>
</excludes>
</instrumentation>
<formats>
<format>html</format>
<format>xml</format>
</formats>
<check>
</check></configuration>
</plugin>
</plugins>
</reporting>
</project>
