JaCoCo Offline Instrumentaion and Integration Test Coverage Reports

I have been trying to implement JaCoCo offline code coverage in a JBoss server using an instrumented EAR for deployment and the jacococagent.jar in order to track code coverage of external integration testing running against said JBoss.

I have been following guides such as these:

http://www.eclemma.org/jacoco/trunk/doc/offline.html

http://automationrhapsody.com/code-coverage-with-jacoco-offline-instrumentation-with-maven/

I feel I am pretty close as everything SEEMS to be working, however, when I load the coverage report up in eclipse's EclEmma plugin, it reports as 0 coverage for everything (which I know is wrong).

Here's my setup:

Here's the maven plugin configuration:

                <plugin>
                <groupId>org.jacoco</groupId>
                <artifactId>jacoco-maven-plugin</artifactId>
                <version>${jacoco.version}</version>
                <configuration>
                    <!-- <destFile>${sonar.jacoco.reportPath}</destFile> -->
                    <append>true</append>

                    <excludes>
                        <exclude>**/dao/**/*Dao*</exclude>
                        <exclude>**/dao/**/*DAO*</exclude>
                        <exclude>**/dao/**/*Vo*</exclude>
                        <exclude>**/dao/**/*VO*</exclude>
                        <exclude>**/ui/**/*</exclude>
                        <exclude>**/*Vo.*</exclude>
                        <exclude>**/*VO.*</exclude>
                        <exclude>**/test/**/*</exclude>
                        <exclude>**/tester/**/*</exclude>
                    </excludes>

                </configuration>
                <executions>
                    <execution>
                        <id>pre-unit-test</id>
                        <goals>
                            <goal>prepare-agent</goal>
                        </goals>
                        <configuration>
                            <destFile>${sonar.jacoco.reportPath}</destFile>
                        </configuration>
                    </execution>
                    <execution>
                        <id>unit-test-report</id>
                        <phase>test</phase>
                        <goals>
                            <goal>report</goal>
                        </goals>
                        <configuration>
                            <dataFile>${sonar.jacoco.reportPath}</dataFile>
                        </configuration>
                    </execution>
                    <execution>
                        <id>jacoco-instrument</id>
                        <phase>test</phase>
                        <goals>
                            <goal>instrument</goal>
                        </goals>
                        <configuration>
                            <skip>${jacoco.skip.instrument}</skip>
                            <!-- <skip>false</skip> -->
                        </configuration>
                    </execution>
                </executions>
            </plugin>

Here's my jacoco-agent.properties file:

destfile=/stage/live_integration_jacoco.exec
output=file
dumponexit=true
append=true

I'm bundling the JaCoCo Agent JARs right inside the EAR as these dependencies (the second one is just what jacocoagent.jar is labelled as in our repository):

        <dependency>
            <groupId>org.jacoco</groupId>
            <artifactId>org.jacoco.agent</artifactId>
            <version>${jacoco.version}</version>
        </dependency>

        <dependency>
            <groupId>org.jacoco.build</groupId>
            <artifactId>org.jacoco.jacocoagent</artifactId>
            <version>${jacoco.version}</version>
        </dependency>

Here's my process:

I run this on the project: mvn clean install -U -Djacoco.skip.instrument=false

And that generates my instrumented EAR artifact. I have verified that the classes in there are indeed instrumented by JaCoCo by decompiling a few of them.

I take that EAR that has instrumented code, the jacococagent.jar included in it, and the jacoco-agent.popreties file included as well and deploy that to JBoss. JBoss starts just fine (it used to get ClassNotFound exception before I started bundling jacocoagent.jar in it directly).

The "/stage/live_integration_jacoco.exec" file is created at this point with a size of '0'.

I run some tests on and against the server, even some manual testing, then stop the application.

The "/stage/live_integration_jacoco.exec" file now has data (30-60kb of data so far in my observations).

I import that exec file into eclipse and it loads without any errors and shows the classes in the project, however it reports 0 coverage on everything.

Well, I'm not sure what else to try at this point.

Does anyone have some thoughts on how to get it correctly generating the coverage report in my situation?

Thanks!
