I guess the instrumentation agent only instruments the one module

This is wrong - JaCoCo agent performs instrumentation of all classes.

Code Coverage discrepency on Maven multi-module project - Eclipse EclEmma vs SonarQube

Hi Brad, Please have a look at to me seems that not counting Gradle it describes exactly your case where tests in one module cover classes in another module. EclEmma itself is structured like that and uses Maven - e.g. tests in module org.eclipse.eclemma.core.test cover classes in module org.eclipse.eclemma.core. And EclEmma is configured as described in mentioned above post: Most common trick to cross boundaries - is to collect all coverage information into single location. This allows…

which IMO pretty well describes case where tests in one module cover classes in another module.
