SonarCloud integration

Integrations SonarCloud integration

How to integrate your workflows with SonarCloud using codemagic.yaml

SonarCloud is SonarQube’s cloud-based code quality and code security service for projects hosted in cloud-based Git repositories such as GitHub, Bitbucket, GitLab and Azure DevOps. It can be used as part of your CI/CD workflow to analyse your code each time you commit new code.

Sample projects that show how to configure SonarQube / SonarCloud integration are available in our sample projects repository for Android and iOS.

Create a SonarCloud account

You will need access to a SonarCloud account and can sign up for free. This will allow you to work with public repositories.

Add your app to SonarCloud

Log into SonarCloud here
Enter an organization key and click on Continue.
Choose the Free plan and click on Create Organization.
Click on My Account.
Under the Security tab, generate a token by entering a name and clicking on Generate.
Copy the token so you can use it as an environment variable in your Codemagic workflow.
Click on the “+” button in the top-right corner, and select Analyze a new project to add a new project.
Select the project and click on Set Up.
Wait for the initial analysis to complete, then modify the Last analysis method.
Turn off the SonarCloud Automatic Analysis.

You can now upload code analysis reports to SonarCloud from your CI/CD pipeline.

Configuring access to SonarCloud in Codemagic

There are three environment variables that need to be added to your workflow for the SonarCloud integration: SONAR_TOKEN, SONAR_PROJECT_KEY, and SONAR_ORG_KEY.

SONAR_TOKEN is the token you created when setting up your account
SONAR_PROJECT_KEY can be obtained from your project settings once it has been added to SonarCloud
SONAR_ORG_KEY is also obtained from your SonarCloud project settings

Open your Codemagic app settings, and go to the Environment variables tab.
Enter the desired Variable name, e.g. SONAR_TOKEN.
Enter the required value as Variable value.
Enter the variable group name, e.g. sonarcloud_credentials. Click the button to create the group.
Make sure the Secret option is selected.
Click the Add button to add the variable.
Repeat the process to add all of the required variables.
Add the sonarcloud_credentials group in your codemagic.yaml file

  environment:
    groups:
      - sonarcloud_credentials

To use SonarCloud with Android projects, you need to add the sonarqube plugin to the app/build.gradle file:

plugins {
    ...
    id "org.sonarqube" version "3.3"
    ...
}

You also need to set Sonarcloud properties in the same app/build.gradle file

sonarqube {
    properties {
        property "sonar.host.url", "https://sonarcloud.io"
        property "sonar.branch", System.getenv("CM_BRANCH")
        property "sonar.projectKey", System.getenv("SONAR_PROJECT_KEY")
        property "sonar.organization", System.getenv("SONAR_ORG_KEY")
        property "sonar.branch.name", System.getenv("CM_BRANCH")
        property "sonar.branch.target", System.getenv("CM_PULL_REQUEST_DEST")
        property "sonar.login", System.getenv("SONAR_TOKEN")
    }
}

Finally, add the scripts to build the debug version and generate the analysis report to your codemagic.yaml file

  scripts:
    - name: Generate debug build
      script: | 
        ./gradlew assembleDebug        
    - name: Generate and upload code analysis report
      script: | 
        ./gradlew sonarqube

An Android sample project that shows how to configure SonarCloud integration is available here

To use SonarCloud with iOS projects, you need to:

install the Sonar Scanner
generate a debug build of your project
convert the coverage report to Sonarqube format
generate and upload code analysis report

To convert the coverage report to Sonarqube format, create a bash script in your project’s root folder named xccov-to-sonarqube-generic.sh with the following content:

#!/usr/bin/env bash
set -euo pipefail

function convert_file {
  local xccovarchive_file="$1"
  local file_name="$2"
  local xccov_options="$3"
  echo "  <file path=\"$file_name\">"
  xcrun xccov view $xccov_options --file "$file_name" "$xccovarchive_file" | \
    sed -n '
    s/^ *\([0-9][0-9]*\): 0.*$/    <lineToCover lineNumber="\1" covered="false"\/>/p;
    s/^ *\([0-9][0-9]*\): [1-9].*$/    <lineToCover lineNumber="\1" covered="true"\/>/p
    '
  echo '  </file>'
}

function xccov_to_generic {
  echo '<coverage version="1">'
  for xccovarchive_file in "$@"; do
    if [[ ! -d $xccovarchive_file ]]
    then
      echo "Coverage FILE NOT FOUND AT PATH: $xccovarchive_file" 1>&2;
      exit 1
    fi
    local xccov_options=""
    if [[ $xccovarchive_file == *".xcresult"* ]]; then
      xccov_options="--archive"
    fi
    xcrun xccov view $xccov_options --file-list "$xccovarchive_file" | while read -r file_name; do
      convert_file "$xccovarchive_file" "$file_name" "$xccov_options"
    done
  done
  echo '</coverage>'
}

xccov_to_generic "$@"

All of the other steps will be performed using scripts in your codemagic.yaml file:

  scripts:
    - name: Install Sonar Scanner
      script: | 
        brew install sonar-scanner
    - name: Generate debug build
      script: | 
        xcodebuild \
          -project "$XCODE_PROJECT" \
          -scheme "$XCODE_SCHEME" \
          -sdk iphonesimulator \
          -destination 'platform=iOS Simulator,name=iPhone 12 Pro,OS=14.5' \
          -derivedDataPath Build/ \
          -enableCodeCoverage YES \
          clean build test CODE_SIGN_IDENTITY="" CODE_SIGNING_REQUIRED=NO
    - name: Convert coverage report to Sonarqube format
      script: | 
        bash xccov-to-sonarqube-generic.sh Build/Logs/Test/*.xcresult/ > sonarqube-generic-coverage.xml
    - name: Generate and upload code analysis report
      script: | 
        export PATH=$PATH:$CM_BUILD_DIR/sonar-scanner/bin    
        sonar-scanner \
          -Dsonar.projectKey=$SONAR_PROJECT_KEY \
          -Dsonar.organization=$SONAR_ORG_KEY \
          -Dsonar.host.url=https://sonarcloud.io \
          -Dsonar.login=$SONAR_TOKEN \
          -Dsonar.projectVersion=1.0.0 \
          -Dsonar.sources=. \
          -Dsonar.cfamily.build-wrapper-output.bypass=true \
          -Dsonar.coverageReportPaths=sonarqube-generic-coverage.xml \
          -Dsonar.c.file.suffixes=- \
          -Dsonar.cpp.file.suffixes=- \
          -Dsonar.objc.file.suffixes=-
