Project not found error on some branches

The problem

We are using GitLab Pipelines to scan our code on every commit. This worked for the past years, however recently we started having problems. When we perform a code analysis for a dotnet application on a branch other than develop, we get the following error:

ERROR: Project not found. Please check the ‘sonar.projectKey’ and ‘sonar.organization’ properties, the ‘SONAR_TOKEN’ environment variable, or contact the project administrator to check the permissions of the user the token belongs to
ERROR:
The SonarScanner did not complete successfully

However, if we run a code analysis on the develop branch the analysis succeeds.

Environment variables

I checked the environment variables:

Variable Value Environment Protected
SONAR_HOST https://sonarcloud.io/ All No
SONAR_TOKEN [redacted] All No
SONAR_ORGANIZATION [redacted] All No
SONAR_PROJECT_KEY [redacted] All No

So the same env variables are being used on all branches.

Command

We are using the following commands to run the analysis:

dotnet-sonarscanner begin /n:$solutionName /key:$projectKey /v:"$version" /d:sonar.token="$SONAR_TOKEN" /d:sonar.host.url="$SONAR_HOST" /d:sonar.cs.opencover.reportsPaths="test/**/coverage.opencover.xml" /d:sonar.coverage.exclusions="$coverageExclusions" $sonarParams /o:$SONAR_ORGANIZATION

dotnet build

dotnet-sonarscanner end /d:sonar.token=$SONAR_TOKEN

Frontend scan

We don’t have this problem with our frontend scans (vuetify project). We use this command for the scan:

sonar-scanner -Dsonar.organization=$SONAR_ORGANIZATION -Dsonar.projectKey=$SONAR_PROJECT_KEY -Dsonar.token=$SONAR_TOKEN -Dsonar.host.url=$SONAR_HOST -Dsonar.sources=$SONAR_SOURCES -Dsonar.tests=$SONAR_TESTS -Dsonar.javascript.lcov.reportPaths=$SONAR_JAVASCRIPT_LCOV_REPORTPATHS -Dsonar.testExecutionReportPaths=$SONAR_TEST_EXECUTION_REPORTPATHS -Dsonar.test.inclusions=$SONAR_TEST_INCLUSIONS -Dsonar.qualitygate.wait=true

The enviroment variables used are the same as the dotnet scan.

Summary

So suddenly code analysis of dotnet applications on branches other than develop stopped working. Does anybody have an idea what can cause this?
Thanks in advance!

Hey there.

Total shot in the dark, but does wrapping your project key and organization in quotes (like you have for the version) help?

dotnet-sonarscanner begin /n:$solutionName /key:"$projectKey"... /o:"$SONAR_ORGANIZATION"

I’d also be curious to know what this resolves to:

Hi Colins,

Thanks for thinking along. I tried wrapping the two variables in quotes but that didn’t change anything.

The $sonarParams resolves to: /d:sonar.qualitygate.wait=true

I added some echo’s to check if the parameters have the correct values and everything seems to be correct. Really confused on why this only happens on branches other than develop.

Thanks.

I’m going to reach out via PM with some additional troubleshooting steps.

Just to tidy this up, the issue was ultimately the same as here:
