SonarQube - Multimodule project based on filesystem hierarchy - sonarqube

Question

Some cvsrepository named Foo has several modules, f.e. module1, module2, ...
A buildscript does cvs checkout, compile and building the module.jar for all modules.
After the build has finished the filesystem looks like that :
Foo/module1/src
/bin
/module2/src
/bin
...
Now i want to use the sonartask like that :
Define the global sonar properties like sonar.username ... sonar.projektName=Foo for MainProject and sonar.modules=module1.module2,... for the modules.
Afterwards looping over the module folders, setting module specific sonar properties,
like sonar.projectName (for modulename) sonar.sources, sonar.binaries etc.
Looping works fine, but it seems as sonar wants a single build.xml for every submodule.
So i need another possibility for grouping modules.
I only found a commercial plugin => Portfolio Management plugin but need another solution.
-- EDIT --
I already found and tried to use the examples from github and documentation, but it seems theyrequire one main build file and a build.xml in every module folder.
Whereas my situation is different. There's only one build.xml that contains a javac + jar target for every module of my project. When build is done, the resulting filesystem looks like mentioned above.
The build is part of the deployment workflow which is driven by a xmlproperty file, that contains the projectname and all modulenames of that deployment job among other things.
Now after the build is done, in the next antfile i want to loop over the modules in that xmlproperty file via xmltask, pointing the module specific properties to filesystem, f.e. sonar.sources=/Foo/module1/src sonar.binaries=/Foo/module1/bin and call <sonar:sonar/> . Overriding of module specific properties in the loop is done via Flaka <let>
After all it's just looping over an existing filesystem setting the sonar poperties and calling the sonar task with approiate properties.
-- EDIT after comment --
Tried it like that :
build.xml
<project name="sonar" xmlns:fl="antlib:it.haefelinger.flaka" xmlns:sonar="antlib:org.sonar.ant">
<fl:install-property-handler/>

I tried also to set the basedir attribute to the value of my ${ant.working.dir}, where all binariues and src folders reside, didn't work either.

Answer 1

See documentation : http://docs.codehaus.org/display/SONAR/Analyzing+with+SonarQube+Ant+Task#AnalyzingwithSonarQubeAntTask-Multi-moduleProject
And example : https://github.com/SonarSource/sonar-examples/tree/master/projects/multi-module/ant

Answer 2

I had a similar problem. When you run the ant task from eclipse, sonar errors are not showed. so, I figure out the problem when the ant ask was executed from command console.
I had two problems:
The sonar.host.url property is mandatory
The sonar.projectKey could not contain special characters, for instance space
