Java coverage not present in HTML report

[ilmirons]

Hi. I have a project with Java and Scala sources, but scoverage report shows only Scala classes coverage. Here is the layout of the project and a pom.xml snippet. Note that Scala test cover both Java and Scala file. Is this a bug? Is there a way to have my Java coverage rendered in HTML by the plugin?

Thanks for your work.

Hi @ilmirons
afaik this plugin instruments only Scala code and it can't get coverage from Java code.
most likely you will need to get coverage for Scala and Java code separately
