there is a lack of support for JaCoCo Agent configuration options: Missing options: - destfile - append - exclclassloader - inclbootstrapclasses - inclnolocationclasses - sessionid (defaulted to instance uuid) - dumponexit - classdumpdir - jmx Of particular interest to me is being able to set a custom sessionid value ( app name, git hash, etc). Is there any particular reason why the option set is so limited by default in the current implementation? Sources: https://www.eclemma.org/jacoco/trunk/doc/agent.html
