When running Sonar Runner 2.4 against SonarQube 5.1 RC2 I get this error:
ERROR: Error during Sonar runner execution

The same thing works with SonarQube 5.0.1.
Maybe some defensive programming would have been good in Sonar Runner. A NPE does not tell anything meaningful to a user. I suggest that they include an assertion and if there is a problem that a useful exception message is output.
回答1:
Most likely some sonar property thats expected a directory were defined with something containing "..". Unfortunately, in my tests, sonar expects an absolut path. I had problems in sonar-ant-runner with sonar.sources, sonar.java.binaries and sonar.projectBaseDir properties.
