NPE when scanning a merge branch in Jenkins

scanner
jenkins

(Alain O'Dea) #1

We’re trying to scan a merge branch to avoid issues with the base branch changing between when the PR is pushed and when it is scanned. That was done to address an issue I noted here:

  • versions used (SonarQube, Scanner, Plugin, and any relevant extension)
    SonarQube Enterprise 7.4.0.18908
    SonarQube Scanner 3.2.0.1227
    SonarQube Scanner for Jenkins 2.8.1

  • error observed
    A null pointer when trying to load the commit during the scanner execution:

  • potential workaround
    Investigating if replacing env.GIT_COMMIT with sh ‘git rev-parse HEAD’ will correct state.

(Alain O'Dea) #2

This works to fix the issue if run between the custom checkout and the sh that runs sonar-scanner:

env.GIT_COMMIT = sh 'git rev-parse HEAD'

Hi,

Thanks for the followup!
