I'm trying to merge some exec files and after that generate a code coverage report (html, xml, csv). But when I use my merged .exec file and generate the report with the classes, the report shows all 0% code coverage.

When I use single exec file I'm merging and create the report, it will show some coverage (6%).

Pls, help me to find a solution.

This is my pom.xml file.

Hi,

maybe the merge task does not find the execution data files and therefore dows create an empty exec file? You filter is

> <fileset dir="jacoco" includes="*.exec"/>

but you exec files seems to be located in a subdirectory:

> jacoco/master/jacoco.exec

So probably it should read includes=“**/*.exec”?

The merge task logs "Loading execution data file …” for each file which is merged. Check your your logs for this.
