Hi, I'm struggling with the following and running out of options I can think of...
The original issue was that JaCoCo had a different coverage than IntelliJ (java code running via maven). Diving into the JaCoCo coverage report I found out that a complete package was simply not covered. In the sessions of JaCoCo, the classes of that package were also not listed. (Other packages had no issues and had coverage and where also listed in the sessions) I dumped the classes by specifying a classDumpDir and there only the test classes of that package were dumped. The classes under test were nowhere to be found. I already found out that the only reason for a class not to be dumped, is that it's filtered prior to instrumentation (see https://github.com/jacoco/jacoco/blob/master/org.jacoco.agent.rt/src/org/jacoco/agent/rt/internal/CoverageTransformer.java#L85 ) and that these are the only reasons to be filtered: ( see https://github.com/jacoco/jacoco/blob/master/org.jacoco.agent.rt/src/org/jacoco/agent/rt/internal/CoverageTransformer.java#L113-L132 ) - they are explicitly excluded / not included according to your configuration - their class loader excluded according to your configuration ( see agent option "exclclassloader", which defaults to "sun.reflect.DelegatingClassLoader" ) - their class loader does not preserve source location ( see agent option "inclnolocationclasses", which defaults to "false" ) - they are loaded by a bootstrap class loader Next to that I also learned that there's a known limitation in JaCoCo, namely that it has no coverage for exceptions. The latter isn't what's happening here as there are also tests without exceptions in them and even when I remove these tests altogether, the issue stays the same. So based upon the info from above I tried the following section in the pom: <plugin> <groupId>org.jacoco</groupId> <artifactId>jacoco-maven-plugin</artifactId> <version>${jacoco.version}</version> <executions> <execution> <id>agent</id> <goals> <goal>prepare-agent</goal> </goals> </execution> <execution> <id>report</id> <phase>site</phase> <goals> <goal>report</goal> </goals> </execution> </executions> <configuration> <propertyName>jacoco.agent.argLine</propertyName> <!-- default: argLine --> <includes> <include>com/sometool/**</include> </includes> <exclClassLoaders>false</exclClassLoaders> <inclBootstrapClasses>true</inclBootstrapClasses> <inclNoLocationClasses>true</inclNoLocationClasses> <destFile>${project.build.directory}/jacoco-integration.exec</destFile> <!-- agent --> <dataFile>${project.build.directory}/jacoco-integration.exec</dataFile> <!-- report --> </configuration> </plugin> But still I have no classes dumped by JaCoCo from that package let alone some coverage.... Any help would be greatly appreciated. Probably it's something simple but I'm simply not seeing it.
