enkinsfile Example with SonarQube and OWASP ZAP Integration

pipeline {
agent any

// Define tools versions
tools {
maven 'Maven 3.6.3'
jdk 'OpenJDK 11'
}

stages {
stage('Checkout') {
steps {
// Check out source code from version control
checkout scm
}
}

stage('Static Code Analysis with SonarQube') {
steps {
// Run SonarQube scanner
script {
withSonarQubeEnv('SonarQubeServer') {
sh 'mvn clean verify sonar:sonar'
}
}
}
}

stage('Dynamic Security Testing with OWASP ZAP') {
steps {
// Assuming OWASP ZAP is set up to run as a daemon on a known host
sh '''
zap-cli start --start-options '-config api.disablekey=true'
zap-cli open-url http://your-application-url.com
zap-cli spider http://your-application-url.com
zap-cli active-scan --recursive http://your-application-url.com
zap-cli report -o zap-report.html -f html
zap-cli stop
'''
// Archive the ZAP report
archiveArtifacts artifacts: 'zap-report.html', fingerprint: true
}
}

stage('Deploy') {
steps {
// Deploy your application
sh './deploy.sh'
}
}
}

post {
always {
// Include steps to clean up or notify based on the outcome of the pipeline
echo 'The pipeline execution is complete.'
}
}
}

Key Components:
