How to set sonar.projectBaseDir in SonarQube Scanner for Jenkins? - sonarqube

Question

I try to analyze one module of a multi module project in Jenkins with SonarQube Scanner plug-in (version 2.5). Unfortunately, Jenkins picks the wrong module as working directory.
In this particular case, I could change the order of the modules, but in general (more than one analyzed module) it is not working. So I want to fix the problem with the property sonar.projectBaseDir, see Advanced SonarQube Scanner Usages:
Alternate Analysis Directory
If the files to be analyzed are not in the directory where the analysis starts from, use the sonar.projectBaseDir property to move analysis to a different directory. E.G. analysis begins from jenkins/jobs/myjob/workspace but the files to be analyzed are in ftpdrop/cobol/project1.
sonar-project.properties
sonar.projectBaseDir=/home/ftpdrop/cobol/project1
sonar.sources=src
sonar.cobol.copy.directories=/copy
I tried following ways to set the sonar.projectBaseDir property to right module (module2 instead of module1):
sonar.projectBaseDir in sonar-project.properties file
But it doesn't work. The property in sonar-project.properties file is ignored. The log shows that the property is overriden with JVM option:
/Users/test/jenkinsslave/tools/hudson.plugins.sonar.SonarRunnerInstallation/SonarQube_Scanner_2.8/bin/sonar-scanner -X -e -Dsonar.host.url=http://sonarqube:9090 -Dproject.settings=/Users/test/jenkinsslave/workspace/Test/module2/sonar-project.properties -Dsonar.projectBaseDir=/Users/test/jenkinsslave/workspace/Test/module1
I think that is a bug in SonarQube Scanner plug-in, because project.settings is incompatible with sonar.projectBaseDir, see Advanced SonarQube Scanner Usages:
The property project.settings can be used to specify the path to the project configuration file (this option is incompatible with the project.home and sonar.projectBaseDir properties).
sonar.projectBaseDir as JVM Options
But it doesn't work. The property is ignored. The log shows that the property is overriden:
/Users/test/jenkinsslave/tools/hudson.plugins.sonar.SonarRunnerInstallation/SonarQube_Scanner_2.8/bin/sonar-scanner -X -e -Dsonar.host.url=http://sonarqube:9090 -Dsonar.projectBaseDir=/Users/test/jenkinsslave/workspace/Test/module1
sonar.projectBaseDir as Additional arguments
But it doesn't work. The log shows that the property is configured twice:
/Users/test/jenkinsslave/tools/hudson.plugins.sonar.SonarRunnerInstallation/SonarQube_Scanner_2.8/bin/sonar-scanner -Dsonar.projectBaseDir=/Users/test/jenkinsslave/workspace/Test/module2 -X -e -Dsonar.host.url=http://sonarqube:9090 -Dsonar.projectBaseDir=/Users/test/jenkinsslave/workspace/Test/module1
I think that is a bug in SonarQube Scanner plug-in, because it should not add sonar.projectBaseDir option if there is already such option.

Answer 1

I found a solution, I have to add the property sonar.projectBaseDir as Analysis properties.
Configuration:
