Sonarqube Gitlab integration issue with sonar-scanner.properties file - gitlab

Question

I have a two projects in GitLab and I am trying to integrate SonarQube with my GitLab projects.
Project 1
I have added the 'sonar-scanner.properties' file to Project1 and it's as follows:
sonar-scanner.properties
# SonarQube server
# sonar.host.url & sonar.login are set by the Scanner CLI.
# See https://docs.sonarqube.org/latest/analysis/gitlab-cicd/.
# Project settings.
sonar.projectKey=Trojanwall
sonar.projectName=Trojanwall
sonar.projectDescription=My new interesting project.
sonar.links.ci=https://gitlab.com/rmesi/trojanwallg2-testing/-/pipelines
#sonar.links.issue=https://gitlab.com/rmesi/trojanwallg2-testing/
# Scan settings.
sonar.projectBaseDir=./
#sonar.sources=./
sonar.sources=./
sonar.sourceEncoding=UTF-8
sonar.host.url=http://sonarqube.southeastasia.cloudapp.azure.com:31000
sonar.login=4f4cbabd17914579beb605c3352349229b4fd57b
#sonar.exclusions=,**/coverage/**
# Fail CI pipeline if Sonar fails.
sonar.qualitygate.wait=true
Then I added the sonar scanner job in the gitlab-ci.yml file:
gitlab-ci.yml
sonar-scanner-trojanwall:
stage: sonarqube:scan
image:
name: sonarsource/sonar-scanner-cli:4.5
entrypoint: [""]
variables:
# Defines the location of the analysis task cache
SONAR_USER_HOME: "${CI_PROJECT_DIR}/.sonar"
# Shallow cloning needs to be disabled.
# See https://docs.sonarqube.org/latest/analysis/gitlab-cicd/.
GIT_DEPTH: 0
cache:
key: "${CI_JOB_NAME}"
paths:
- .sonar/cache
script:
- sonar-scanner
only:
- Production
- /^[\d]+\.[\d]+\.1$/
when: on_success
After this, I configured the two variables: 'SONAR_HOST_URL' and 'SONAR_TOKEN' and then, ran the pipeline. It worked perfectly fine for the Project 1.
Project 2
Then, I needed to do the same for the Project 2 as well. I needed the sonar scanner to go into the Project 2, scan and analyze. For that, I created another project in SonarQube with a new token.
I needed to configure in such a way that when the pipeline for Project 1 is triggered, it scans both Project 1 and 2.
For that, I added another job in Project1's pipeline.
It's as follows:
gitlab-ci.yml
sonar-scanner-test-repo:
stage: sonarqube:scan
trigger:
include:
- project: 'rmesi/test-repo'
ref: master
file: 'sonarscanner.gitlab-ci.yml'
only:
- Production
- /^[\d]+\.[\d]+\.1$/
when: on_success
I tried to setup a downstream pipeline to trigger a yaml file in Project 2. So, when The pipeline in Project 1 is triggered and when the job 'sonar-scanner-test-repo' gets triggered, another yaml file in Project 2 is run as a down stream pipeline. That YAML file is as follows:
sonarscanner.gitlab-ci.yml
stages:
- sonarqube:scan
variables:
CI_PROJECT_DIR: /builds/rmesi/test-repo
sonar-scanner:
stage: sonarqube:scan
image:
name: sonarsource/sonar-scanner-cli:4.5
entrypoint: [""]
variables:
# Defines the location of the analysis task cache
SONAR_USER_HOME: "${CI_PROJECT_DIR}/.sonar"
# Shallow cloning needs to be disabled.
# See https://docs.sonarqube.org/latest/analysis/gitlab-cicd/.
GIT_DEPTH: 0
cache:
key: "${CI_JOB_NAME}"
paths:
- .sonar/cache
script:
- cd /builds/rmesi/
- git clone https://gitlab.com/rmesi/test-repo.git test-repo
- sonar-scanner
Then I added the 'sonar-project.properties' file in Project2 which is as follows:
sonar-project.properties
# SonarQube server
# sonar.host.url & sonar.login are set by the Scanner CLI.
# See https://docs.sonarqube.org/latest/analysis/gitlab-cicd/.
# Project settings.
sonar.projectKey=test-repo
sonar.projectName=test-repo
sonar.projectDescription=My new interesting project.
sonar.links.ci=https://gitlab.com/rmesi/test-repo/-/pipelines
#sonar.links.issue=https://gitlab.com/rmesi/test-repo/
# Scan settings.
sonar.projectBaseDir=/builds/rmesi/test-repo/
sonar.sources=/builds/rmesi/test-repo/, ./
sonar.sourceEncoding=UTF-8
sonar.host.url=http://sonarqube.southeastasia.cloudapp.azure.com:31000
sonar.login=b0c40e44fd59155d27ee43ae375b9ad7bf39bbdb
#sonar.exclusions=,**/coverage/**
# Fail CI pipeline if Sonar fails.
sonar.qualitygate.wait=true
The issue is that, when the down stream pipeline is run, I am getting the following error message:
I figured out that the down stream pipeline is not locating the 'sonar-scanner.properties' in Project 2. (Lines 68 and 74)
Where as, on Project 1 while searching for this step, it shows:
INFO: Project root configuration file: /builds/rmesi/trojanwallg2-testing/sonar-project.properties
But in Project 2 it's not working.
Does anyone know how to fix this?

Answer 1

I found the solution to this, myself.
Required to add
"- cd /build/rmesi/test-repo ; sonar-scanner"
in the script section in the job of the 'sonarscanner.gitlab-ci.yml' file.
That way, the runner maps directly to desired directory and execute the 'sonar-scanner' command there.
