NullPointerException when running SonarScanner

[JonathanNakandala]

I get this crash on the sonar-scanner.

I did try all sorts of tokens and it hasn't seemed to make a difference.
Is there perhaps something I can do to do more debugging?

Run settings:

      sonar-scanner
      -Dsonar.host.url=$SONAR_URL
      -Dsonar.gitlab.project_id=$CI_PROJECT_PATH
      -Dsonar.gitlab.commit_sha=$CI_COMMIT_SHA
      -Dsonar.gitlab.ref_name=$CI_COMMIT_REF_NAME
      -Dsonar.gitlab.user_token=$SONAR_GITLAB_TOKEN
      -Dsonar.gitlab.url=https:/mygitlab.com
      -Dsonar.gitlab.ci_merge_request_iid=$CI_MERGE_REQUEST_IID
      -Dsonar.gitlab.merge_request_discussion=true

There's also a sonar-project.properties with:

sonar.projectKey=<MyProjectKey>
sonar.qualitygate.wait=true
sonar.python.version=3.8
sonar.exclusions=<FoldersList>
sonar.python.pylint.reportPaths=public/lint/parseable.txt

[javamachr]

Seems like config issue - one of projecId or refName is empty. Check $CI_COMMIT_REF_NAME or $CI_PROJECT_PATH value if it is correctly set.

[JonathanNakandala]

Thanks for replying! :)

I added a couple of echoes before the sonar-scanner, it does have values.

$ echo $CI_COMMIT_REF_NAME
experiment-gitlab
$ echo $CI_PROJECT_PATH
jonoGroup/testrepo

[javamachr]

The project ID value is wrong. It is not path it should be ID of project(it is queried by ID via API) that you can find on project page:

[JonathanNakandala]

hmmm, so I manually set it to the value in the config file:

sonar.gitlab.project_id=1452

And also tried setting it with -D

Looks like I'm getting the same error still

btw, I copied using the proejct path for the id from the readme.md:

https://github.com/javamachr/sonar-gitlab-plugin/blob/master/README.md#gitlab-ci

[javamachr]

It seems that it fails to find the project via API. This

-Dsonar.gitlab.url=https:/mygitlab.com

seems like a wrong value - could you please double check that it is correctly pointed to your GL instance? This part of code should not be broken - must be config related I'd say.

Hi!
I also catch this error.
The report is completed, but no comments in MR.
Can the Java version or other dependencies somehow affect?

[javamachr]

It is checking gitlab API using sonar.gitlab.url=https://git/ and projectId and it obviously fails since https://git/ seems to be wrong value and no gitlab server is running there I assume.

[SergeyKraynev]

Thanks for your reply. The URL is correct, the standard SonarQube mechanism sends its comments perfectly.

[javamachr]

Hmm can you try to call the API from sonar machine/container via CURL? It should give you some hints. For some reason sonarqube is unable to reach gitlab api calls.
Just try to call smt like:

curl --header "PRIVATE-TOKEN: <your_access_token>" "https://git/api/v4/projects/410/repository/commits"

And see if it returns something or fails.

[git22ura]

It is ok. There is windows server.

Hmm then it might be related to JAVA not working with that URL.
What certificate do you use on gitlab instance?
With self signed you might need to add CA to your java installation inside sonar so that java process is able to open https.
Maybe a simple java app trying to do the same as CURL did would help to troubleshoot it.

[krejcmat]

I have the same issue. Have any of you solved the problem? Thanks

[moreorover]

Having same issue. here as well.

GitLab 15.11
SonarQube 9.9.1
Sonar Gitlab Plugin 5.3.0

Since this is a null exception I reckon there are not enough checks to provide user with a meaningful error message. Any tips trying to resolve it?

[krejcmat]

I solved it by using sonarqube admin token. The project token wasn't enough..

[moreorover]

I solved it by using sonarqube admin token. The project token wasn't enough..

Anyone facing this issue please make sure first that your technical user gitlab access token is valid by performing the following curl operation:
curl --header "PRIVATE-TOKEN: <your private token>" "https://gitlab.com/api/v4/projects/:id"

I have discovered that the access token I was trying to use was returning 403 response code, when updated the token everything worked.
