Violations Maven Plugin

This is a Maven plugin for Violations Lib. There is also a Gradle plugin and a command line tool.

It can parse results from static code analysis and:

• Report violations in the build log.
• Optionally fail the build depending on violations found.

A snippet of the output may look like this:

Example of supported reports are available here.

A number of parsers have been implemented. Some parsers can parse output from several reporters.

52 parsers and 79 reporters.

Usage

There is a running example here. See also bjurr-bom.

The plugin needs to run after any static code analysis tools, so put it after them in the pom. Having the following in the pom will make the plugin run with mvn validate:
