Jenkins SonarQube Scanner failing with SonarQube 7.1

[Nick Jagger]

Hi,

I've recently upgraded our SonarQube install to version 7.1, and since then the SonarQube Scanner used by Jenkins is failing.

Tech. stack:

• SonarQube: Version 7.1 (build 11001)
  
• SonarQube Scanner: 3.1.0.1141
  
• SonarQube Scanner for Jenkins (plugin): 2.7.1
  
• Jenkins: 2.117

The issue occurs when the Scanner tries to download the sonar-scanner-engine-shaded-7.1-all.jar from the SonarQube installation. I know that the .jar download works okay as I've hit the REST endpoint manually (http://<SONARQUBE_INSTALLATION>/batch/file?name=sonar-scanner-engine-shaded-7.1-all.jar) and downloaded it locally. The Scanner however seems to be having difficulty decoding the file stream, as seen in the stack trace:

I've found the class file which throws this exception and suspect that the shaded jar is corrupt. However, when I download it manually and rename the file, I can access the jar contents without issue.

Has anyone else experienced this issue? Do I need to wait for a fix to the Scanner, or SonarQube installation?

Thanks in advance,

Nick
