How to generate HTML report with Maven FindBugs?

Question

I know a similar question has been asked here, but my setup within pom.xml is a bit different and that answer isn't working for my case.

I have findbugs set up so that when I run [mvn compile findbugs:findbugs], I get the default findbugsXML.xml generated. I would like to get an html file generated so that it's more readable. Below is what I've added to pom.xml in order to get findbugs set up. I'm not sure why the html file isn't being generated given that I've included that specification when making the pom.xml edits. The below was added into the plugins section of build in pom.xml.

I'm using Apache Maven 3.2.3 and Java version: 1.8.0_20. I've also included findbugs-3.0.1.jar and findbugs-maven-plugin-3.0.1.jar in my apache-maven-3.2.3 directory.

There are 4 variables:

• java/JDK version
• maven version
• findbugs plugin version
• findbugs version

With java-1.7, it works on my Windows system with the specified versions of maven, findbugs, findbugs-maven-plugin. Essentially older versions of findbugs does not work with java 8.

With java-1.8, it works if I use version 3.0.1 of findbugs and findbugs-maven-plugin.

Since you have bound findbugs goals to compile task, you just need to run mvn clean compile.
