Thank you for the report. I have added an issue for your request .
We will address it, I also think that having more report formats is a good suggestion.
A few thoughts about the original problem of adding JCov to CI (Jenkins):
- use html publisher plugin to show JCov html report
- plot build data with plot plugin to look at the coverage trend for builds
( it will require using grep and sed to get data from overview-summary.html to plot.csv )
- create JCov plugin for Jenkins.
The latest item and Maven plugin opens a little bit bigger discussion for Code Tools projects:
Could we have tool's plugins sources in tool’s repository?
