Introduction

jacoco-cov-badge-maven-plugin is a maven plugin which can generate svg, png or jpg badges locally by calculating code coverage from jacoco report.

Jacoco is code coverage utility which generates nice report for Java Based projects and is generally integrated as maven build plugin.

There are several online utilities like coveralls, shields.io etc. which provides badges as a service.

It is highly inspired from gh-badges which shields.io also uses for generating badges.

Quickstart

The plugin needs jacoco.csv report, for it to function correctly.
So you can bind it to any phase after the jacoco.csv reports gets generated.

Although these are configurable, but some assumptions made by the plugin:
Default jacoco report location: ${project.reporting.outputDirectory}/jacoco/jacoco.csv
Default Output location:${project.build.directory}/coverage.svg
