Problems with Sonar Analyzing a PHP Project

I want to parse a PHP project using sonar. I installed PHP-Plugin and PHPunit and created the sonar-project.properties file with all the necessary information. I use Java-runner to execute. I tried hundreds of possible solutions for my problem, but nothing works. I always get this error:

Exception in thread "main" org.sonar.batch.bootstrapper.BootstrapException: org.sonar.api.utils.SonarException: Can't read PhpUnit report : /var/www/smc/.sonar/target/logs/phpunit.xml

This is my properties file:

# required metadata
sonar.projectKey=my:project
sonar.projectName=Social Media Connector
sonar.projectVersion=1.0

# path to source directories (required)
sources=htdocs/website/controllers

# path to test source directories (optional)
#tests=htdocs/website/controllers/tests
#sonar.phpUnit.mainTestClass=htdocs/website/controllers/tests/website/controllers/blubbTest.php

# path to project binaries (optional), for example directory of Java bytecode
#binaries=binDir

# optional comma-separated list of paths to libraries. Only path to JAR file and path to directory of classes are supported.
#libraries=path/to/library.jar,path/to/classes/dir


# Uncomment those lines if some features of java 5 or java 6 like annotations, enum, ...
# are used in the source code to be analyzed
#sonar.java.source=1.5
#sonar.java.target=1.5


# Uncomment this line to analyses a project which is not a java project.
# The value of the property must be the key of the language.
sonar.language=php

# Advanced parameters
#my.property=value
#sonar.phpUnit.skip=true
sonar.phpUnit.analyze.test.directory=true

Any ideas?
