I've read the [Testing Framework Cheatsheet](https://github.com/elastic/elasticsearch/blob/2.x/TESTING.asciidoc) and tried to execute Jacoco coverage over my unit tests as instructed:
`mvn -Dtests.coverage test jacoco:report`
But it doesn't work. Maven fails, debugging it I found the exception:
`java.lang.RuntimeException: unable to install test security manager Caused by: java.lang.NullPointerException`
Removing the jacoco report goal results the same:
`mvn -Dtests.coverage test`
What is missing in my project? Which configurations in Elasticsearch master pom should I use in my project to fix it?

Found the problem. The property `tests.coverage.dir` must be set. I did it in my project POM.

Like so:
``
`org.apache.maven.plugins`
`maven-surefire-plugin`
``
``
`${project.build.directory}`
``
