How to add "merged" report to Maven site

[Christian Gendreau]

Hi,

I'm trying to configure the jacoco-maven-plugin to generate 3 reports (unit, integration and a merged report) and have them available in the index.html of the maven site plugin.

          <!-- Merge jacoco.exec from unit and integrations tests -->
          <execution>
            <id>merge-results</id>
            <phase>verify</phase>
            <goals>
              <goal>merge</goal>
            </goals>
            <configuration>
              <fileSets>
                <fileSet>
                  <directory>${project.build.directory}</directory>
                  <includes>
                    <include>*.exec</include>
                  </includes>
                  <excludes>
                    <exclude>jacoco-aggregate.exec</exclude>
                  </excludes>
                </fileSet>
              </fileSets>
              <destFile>${project.build.directory}/jacoco-aggregate.exec</destFile>
            </configuration>
          </execution>

          <execution>
            <id>aggregate-report</id>
            <phase>verify</phase>
            <goals>
              <goal>report</goal>
            </goals>
            <configuration>
              <outputDirectory>${project.reporting.outputDirectory}/jacoco-aggregate</outputDirectory>
              <dataFile>${project.build.directory}/jacoco-aggregate.exec</dataFile>
            </configuration>
          </execution>

The jacoco-aggregate folder will contain a merged report but if I add the following configuration in the report section of my pom:

      <plugin>
        <groupId>org.jacoco</groupId>
        <artifactId>jacoco-maven-plugin</artifactId>
      </plugin>

I end up with an empty aggregate report since "report-aggregate" will generate a new report with all the .exec from my build folder.

If I use the following configuration:

      <plugin>
        <groupId>org.jacoco</groupId>
        <artifactId>jacoco-maven-plugin</artifactId>
        <reportSets>
          <reportSet>
            <reports>
              <report>report</report>
              <report>report-integration</report>
            </reports>
          </reportSet>
        </reportSets>
      </plugin>

my merged report (in jacoco-aggregate folder) is still available but it is not picked up by the maven site since it's not in the reportSet.

So my question is: How could I add my "merged" report to the maven site without having jacoco-aggregate creating a new one?

Thanks!

Let me know if you need more information and/or snippets.

Hi,

Created dedicated module for combined report that will use only "<report>report-aggregate</report>".
