title: Maven Findbugs plugin not executing with mvn site command
body: <p>I'm trying to get Findbugs working with an existing/mature Maven project.</p>
  
  <p>I added the following to the <code>&lt;plugins&gt;</code> tag in my <code>pom.xml</code>:</p>
  
  <pre><code>&lt;plugin&gt;
    &lt;groupId&gt;org.codehaus.mojo&lt;/groupId&gt;
    &lt;artifactId&gt;findbugs-maven-plugin&lt;/artifactId&gt;
    &lt;version&gt;3.0.5&lt;/version&gt;
    &lt;configuration&gt;
      &lt;effort&gt;Max&lt;/effort&gt;
      &lt;threshold&gt;Low&lt;/threshold&gt;
      &lt;xmlOutput&gt;true&lt;/xmlOutput&gt;
    &lt;/configuration&gt;
  &lt;/plugin&gt;
  </code></pre>
  
  <p>I then see that the Findbugs plugin runs when you run <code>mvn site</code>. Since the build invocation for my project is aleady:</p>
  
  <pre><code>mvn clean jacoco:prepare-agent test site jxr:jxr -Dkey1=123 -Dkey2=456 -Denvironment=DEV
  </code></pre>
  
  <p>...I just run it like I normally do. The build succeeds and I go to my normal site summary in my browser:</p>
  
  <p><a href="https://i.stack.imgur.com/RbHbC.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/RbHbC.png" alt="enter image description here"></a></p>
  
  <p>No where from here can I find any "Findbugs" reports or anything that mentions Findbugs at all. When I do a grep for Findbugs (<code>grep -rl "findbugs" .</code>) I do see that many of my <code>./target/surefire-reports/TEST-*.xml</code> files have the term "<em>findbugs</em>" mentioned in them.</p>
  
  <p>Worth mentioning that I do <em>not</em> see a <code>target/site/findbugs.html</code> file after the successful build...</p>
  
  <p>Any ideas as to where I can find HTML Findbugs output under my Site summary (or anywhere else)? Looking for a nice HTML report showing which (if any) Findbugs checks failed.</p>
