Checking the Code Coverage - Maven

During development you like to see the results Checking the Code Coverage in the development environment. But also when adding the code to the source code repository, the Continuous Integration build, should check the Code Coverage. This is done through the JaCoCo Maven Plug-in.

Action Plan

Add the jacoco-maven-plugin to the Maven project file pom.xml

            <plugin>
                <groupId>org.jacoco</groupId>
                <artifactId>jacoco-maven-plugin</artifactId>
                <version>0.7.7.201606060606</version>

                    </execution>
                </executions>
            </plugin>

Run Maven verify
mvn clean verify
This should give a HTML report in target/site/jacoco/index.html, which shows the details of the code coverage.
