ArgumentNullException in SonarQube Scanner for MSBuild 3.0.2

[m...@soloplan.de]

Hello,

I'm trying to setup a new SonarQube project and connect it to a new Jenkins nightly build. Sadly, I'm getting an ArgumentNullException with not much information to go on. Whatever happens, in my opinion an ArgumentNullException should not surface. It should be handled inside and instead a useful error message should be written to the log.

11:33:29 ERROR: Execution of SonarQube Scanner for MSBuild failed (exit code -532.462.766)

I get the same exception when I execute this command line locally. We have two SonarQube instances, one "production" instance and one "playground" instance to test updates and new configurations. At the moment, they are identical (I've imported the database from production into the playground instance).
Interestingly, when I switch to the production instance, no exception.

It get this exception for any project right now. When running in "verbose" mode the exception seems to happen after downloading the quality profiles from the SonarQube instance (SonarQube is version 6.5 with C# plugin 6.3):

-> callstack as shown above

Has anyone an idea what might be the problem? I'm at a loss right now.

Thanks,

Hi Markus,

In that stacktrace is there a "caused by" line in verbose mode?

Hi Ann,

thanks for your feedback. Sadly, no there is no "caused by" line. I just tried it again. When executing the command line in verbose mode the last line states that it is downloading the active rules from the SonarQube instance, next comes the callstack (and a Windows message box that "SonarQube.Old.Bootstrapper has stopped working"):
