How exclude class from jacoco maven reporting

[glor...@gmail.com]

Hello,
I am trying to exclude a java class from reporting of the maven jacoco plugin. But I do not manage.

I see the coverage is 0% after the exclusion but the class is still in the report html page. Is it possible to remove it from the html report ?

Hi,

Exclusions from instrumentation ( http://www.eclemma.org/jacoco/trunk/doc/instrument-mojo.html#excludes ) is not the same as exclusion from report generation ( http://www.eclemma.org/jacoco/trunk/doc/report-mojo.html#excludes ) - we also have following ticket about inconsistency https://github.com/jacoco/jacoco/issues/34#issuecomment-10205525

In attachment you'll find an example of how to exclude file from report.

My example creates report with excluded file not as part of site generation ("mvn clean package").

As far as I remember - plugins declared in "reporting" section for site generation have completely separate configuration and you don't configure exclusions here.
