Maven Findbugs plugin - How to run findbug on the test classes

Question

Maven version: 3.3.3. Findbugs plugin version: 3.0.1

1. I'm using the findbugs-maven-plugin and I need to run findbugs plugin on src and test classes. Currently, it is only applied to the source classes

   Target
   |_ classes
   |_ test-classes
   |_ findbugs (only have results regarding classes folder)
   

2. I need to do the same for the PMD plugin. Same hint maybe?

                        </goals>
                    </execution>

Answer 1

In the configuration of the findbugs-maven-plugin, you need to explicitely set the includeTests element to true for FindBugs to analyze the test classes:

<plugin>
  <groupId>org.codehaus.mojo</groupId>
  <artifactId>findbugs-maven-plugin</artifactId>
  <version>3.0.1</version>
  <configuration>
    <!-- rest of configuration -->
    <includeTests>true</includeTests>
  </configuration>
</plugin>

Also, the plugin should be bound to the verify phase so that FindBugs is executed after compilation of source and test classes.

For the maven-pmd-plugin, it is actually the same: the element includeTests must be set to true in the plugin configuration.
