I have several levels of nested Maven projects, where every module can participate in the global integration tests. To have a global, multi module coverage, I've configured jacoco to use and share the same file accross modules, using the Maven variable ${session.executionRootDirectory}
:
<execution>
<id>pre-integration-test</id>
<phase>pre-integration-test</phase>
<goals>
<goal>prepare-agent-integration</goal>
</goals>
<configuration>
<propertyName>jacoco.failsafeArgLine</propertyName>
<destFile>${session.executionRootDirectory}/target/jacoco-it.exec</destFile>
</configuration>
</execution>
This way, the same data file is used by each module, no matter how deep it is nested in the submodules. I've checked, a correct data file is generated by jacoco when launching "mvn clean install".
Now the problem appears when launching mvn sonar:sonar
. It seems that the plugin can not replace that variable with the real path. I can see the following in the logs
[INFO] JaCoCoItSensor: JaCoCo IT report not found: /home/tomcat/.jenkins/jobs/MYJOB/workspace/${session.executionRootDirectory}/target/jacoco-it.exec
It doesn't work better when using @{session.executionRootDirectory}
.
Any workaround?
Following a comment in this bug report at SonarSource, advising to use the following configuration:
<plugin>
<groupId>com.github.goldin</groupId>
<artifactId>properties-maven-plugin</artifactId>
<version>0.2.5</version>
<executions>
<execution>
<id>set-sonar.jacoco.reportPath</id>
<goals>
<goal>set-properties</goal>
</goals>
<phase>initialize</phase>
<configuration>
<rawProperties>
sonar.jacoco.itReportPath = ${session.executionRootDirectory}/target/jacoco-it.exec
</rawProperties>
<addDollar>true</addDollar>
</configuration>
</execution>
</executions>
</plugin>
... which was unfortunately not compatible with Maven 3.1+, I've used and built from sources that fork, and then I was able to make everything work correctly with Maven 3.2.3.
