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.

NullPointerException while collecting changed files in branch
(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!

(Sylvain Juge) #5

I’ve just faced a very similar error while trying to analyze with sonarcloud with gradle plugin 2.7.

It works perfectly well on my local machine, but fails on Jenkins while building my pull-request.

I’ve tried to use ‘checkout local branch’ at git checkout to avoid having a ‘detached head’ repo in Jenkins, but it did not help either.

The workaround suggested did not help, it is like I can’t set environment variables.
I’ve tried with env.GIT_COMMIT = ‘’ or by using withEnv(…) block (which seems somehow safer). Whatever I try I always get GIT_COMMIT = null.

What I don’t understand here, is how does setting this env variable changes behavior of the sonar plugin. Is there any fallback to using environment variables when unable to read current repository state ?


update : it also happens with regular branches, not only pull-requests.


update (2) : I’ve reproduced the issue with another simple project, thus this is definitely related to the way Jenkins performs git checkout (sparse checkout, no history nor tags by default, …). Does anyone know what does Sonar plugin uses JGit for exactly in this context ? this might help me find what is currently missing when executed in Jenkins context.


(G Ann Campbell) #6

Hi,

JGit is used at the end of analysis to pull blame data on the files in your project.

 
HTH,

Thanks!

Is there any way to make the plugin what operation is being performed when this exception happen ?
