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] :

##[debug]Finishing: Trigger Jenkins Build
By executing the command in locally also I am getting the same error as Error :

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:/*$::')
