You can study a bit more carefully documentation and mentioned by you blog.
Execution of
java -help
shows
-D<name>=<value>
set a system property
-javaagent:<jarpath>[=<options>]
load Java programming language agent, see
java.lang.instrument
Thus
java -Djavaagent:jacoco-0.8.1/lib/jacocoagent.jar=port=6300
is wrong.
java -javaagent=jacoco-0.8.1/lib/jacocoagent.jar=port=6300
is also wrong because after "-javaagent" should be colon! and equal sign is
only after path.
Correct is:
java -javaagent:jacoco-0.8.1/lib/jacocoagent.jar=port=6300
Exactly as written in https://www.jacoco.org/jacoco/trunk/doc/agent.html
and in mentioned by you blog.
Regards,
Evgeny
