Integrating JaCoCo

Let's integrate JaCoCo into our existing project:

1. First, include the plugin that includes JaCoCo in the POM file:

<plugin> 
   <groupId>org.jacoco</groupId> 
   <artifactId>jacoco-maven-plugin</artifactId> 
   <version>0.7.9</version> 
</plugin> 

The second and third step is to include pre-executions and post-executions into the preceding plugin.

2. The pre-execution prepares the agent to be configured and added to the command line.
3. The post-execution ensures that the reports get created in the output folders:

<executions> <execution> <id>pre-unit-test</id> <goals> <goal>prepare-agent</goal> </goals> <configuration> <destFile>${project.build.directory}/coverage-reports/jacoco-ut.exec</destFile> <propertyName>surefireArgLine</propertyName> ...
