Does jacoco instrument/report on classes in the Boot Class Loader?

[Ted Hulick]

Hi,

Using the Jacoco gradle plugin - I cannot get Jacoco to do coverage on my boot classes - I get 0 coverage although it will add them to the report....

I know for a fact the classes are not loaded until the Jacoco java agent is loaded....

Thoughts?

Hi,

I have feeling that this is about JaCoCo agent option "inclbootstrapclasses" that defaults to "false" - see https://www.jacoco.org/jacoco/trunk/doc/agent.html

> inclbootstrapclasses

> Specifies whether also classes from the bootstrap classloader should be instrumented. Use this feature with caution, it needs heavy includes/excludes tuning.

As you can see on page https://www.jacoco.org/jacoco/trunk/doc/integrations.html JaCoCo Gradle Plugin is not developed by us, so how to configure this agent option using Gradle Plugin is a question to developers of this plugin - https://github.com/gradle/gradle

Regards,

Evgeny
