Hi Markus, when I try this, I get
[xslt] : Error! Error checking type of the expression 'funcall(replace, [step("attribute", 22), literal-e
xpr, literal-expr(.)])'.
I suspect some XSLT 1.0 vs 2.0, ant jar or some such issue (some sites indicate a fn: namespace), I'm using the saxon9he.jar from your example. Any ideas?

Hi there,

I forked the Emma plugin back in October, and got something that more-or-less works for JaCoCo. It does need a few specific fixes:

• JaCoCo collects a slightly different set of metrics than Emma does, and the table headings in the template need to be updated
• the source file line-by-line coverage HTML files have to be included in the produced report
• a few tests from the original Emma plugin are still failing (I updated most of them already, but some will are invalid for JaCoCo)

You can take a look at the current state of it here: https://github.com/jfuerth/emma-plugin/tree/jacoco

Help is very welcome!

On a side note, this topic was suggested as a subject for a GSoC by JBoss (Jonathan is the mentor) https://community.jboss.org/wiki/GSoC12Ideas#A_Jenkins_plugin_to_visualize_Jacoco_code_coverage_reports
Any help of finding and motivating a student for to work on this in the GSoC context is welcome!

EclEmma plugin for Jacoco reports in Eclipse is great. I guess they have a cool API to parse jacoco.exec files and a cleaner way than turning them into Emma reports with XSL.

Have anybody run the jacoco_to_emma.xslt file on maven?

When I run it I get the following error:

[INFO] --- xml-maven-plugin:1.0:transform (default) @ my-app ---
ERROR:  'Error checking type of the expression 'funcall(replace, [step("attribute", 22), literal-expr(/), literal-expr(.)])'.'

Any pointers? Thanks!

Hi Jose
I do not know maven, and you did not provide the maven-config...
I have the xslt still in use (with ant), the only thing I changed in the meantime is, that I use "BRANCH" instead of "COMPLEXITY" on line 102.

@Jose: you should use the jacoco plugin which is already available in version 0.1. See Ognjen's comment for useful links on this topic.
