Throwing an Error while triggering the Jenkins build in GitHub Actions

I am doing an GitHub Actions workflow that triggers the build in Jenkins. Below are the files are created that triggers the build.

config.json:

{
    "buildConfig": {
        "jobName": "subbu_project"
    }
}

trigger_build.yml in GitHub workflows:

---

name: Trigger Jenkins Build

on:
  push:
    branches:
      - "main"

jobs:
  trigger-jenkins:
    runs-on: self-hosted

    steps:
      - name: Trigger Jenkins Build
        shell: bash
        env:
          JENKINS_URL: ${{ secrets.JENKINS_URL || 'http://localhost:8080' }}
          JENKINS_USER: ${{ secrets.JENKINS_USER || 'subbaramaiah_chevuru' }}
          JENKINS_API_TOKEN: ${{ secrets.JENKINS_API_TOKEN }}
          JOB_NAME: ${{ env.JOB_NAME || 'subbu_project' }}
          BUILD_NUMBER: ${{ env.BUILD_NUMBER || '001' }}
          DEPLOY_ENVIRONMENT: development
        run: |
          # Trim trailing slashes from JENKINS_URL
          TRIMMED_JENKINS_URL=$(echo "$JENKINS_URL" | sed 's:/*$::')
          # Clean job name (no need to modify)
          CLEAN_JOB_NAME="$JOB_NAME"
          # Construct the full URL
          FULL_URL="${TRIMMED_JENKINS_URL}/job/${CLEAN_JOB_NAME}/build"
          echo "Full URL: $FULL_URL"
          # Execute the curl command to trigger the Jenkins build
          echo "Executing curl command:"
          curl -v "$FULL_URL" \
               --user "$JENKINS_USER:$JENKINS_API_TOKEN" \
               --header "Content-Type: application/x-www-form-urlencoded" \
               --data-urlencode "BUILD_NUMBER=$BUILD_NUMBER" \
               --data-urlencode "DEPLOY_ENVIRONMENT=$DEPLOY_ENVIRONMENT"

Do you have a Jenkins instance running at localhost:8080 on that self-hosted runner? - Asked by @Azeem

I have installed and started the Jenkins and Action Runner in the PowerShell WSL and below is the output in the GitHub Action [trigger-jenkins][1] :

Solution

  • Looking at the code, I can infer that the only source of unexpected double quote is ${{ secrets.JENKINS_USER }} or ${{ secrets.JENKINS_API_TOKEN }}

    To support a double quote in either of these values, try enclosing --user argument in single quotes:

    --user '${{ secrets.JENKINS_USER }}:${{ secrets.JENKINS_API_TOKEN }}'

    Another issue here is this line:

    TRIMMED_JENKINS_URL=$(echo "${{ secrets.JENKINS_URL }}" | sed 's:/*$::')

    echo will add '\n' to the url and sed will pass it through. This will cause the error you see.

    A better option would be

    TRIMMED_JENKINS_URL=$(echo -n "${{ secrets.JENKINS_URL }}" | sed 's:/*$::')
