Maybe I don't understand something, but as long as class files on disk match class files used at runtime (see http://www.eclemma.org/jacoco/trunk/doc/classids.html) you should be able to achieve what you want as following:
cd repo1 && mvn clean jacoco:prepare-agent install -Djacoco.destFile=/tmp/jacoco.exec -Djacoco.append=false cd repo2 && mvn clean jacoco:prepare-agent install -Djacoco.destFile=/tmp/jacoco.exec -Djacoco.append=true cd repo1 && mvn jacoco:report -Djacoco.dataFile=/tmp/jacoco.exec cd repo2 && mvn jacoco:report -Djacoco.dataFile=/tmp/jacoco.exec On Friday, December 2, 2016 at 6:29:56 PM UTC+1, Vincent Massol wrote: > > Hi Evgeny, > > > On 02 Dec 2016, at 17:30, Evgeny Mandrikov <[email protected]> wrote: > > > > Hi, > > > > Name of a property for "report" is "jacoco.dataFile" and not > "jacoco.destFile" - see > http://www.eclemma.org/jacoco/trunk/doc/report-mojo.html#dataFile > > However this property was added in version 0.7.8 that is not yet > released (presented only in snapshot version) - see > http://www.eclemma.org/jacoco/trunk/doc/changes.html > > But prior to 0.7.8 you can define your own property as following: > > <plugin> > > <groupId>org.jacoco</groupId> > > <artifactId>jacoco-maven-plugin</artifactId> > > <configuration> > > <dataFile>${jacoco.dataFile}</dataFile> > > </configuration> > > </plugin> > > Thanks a lot for your answer.
