Java Build & Deployment Automation 🚀 This project automates the build and deployment of Java applications using Bash, Maven, and Apache Tomcat. It is designed as a DevOps mini-project to showcase automation, environment configuration, logging, and CI/CD integration.
Features • Automated build & deploy — packages Java applications with Maven and deploys them to Tomcat • Environment-aware configs — separate settings for Dev, Test, and Prod environments • Logging & error handling — all steps are timestamped and saved to log files • Cron integration — schedule automated deployments at specific times • Jenkins-ready — easily extendable into a CI/CD pipeline
Prerequisites Make sure you have the following installed: • Linux (Ubuntu, CentOS, or Amazon Linux EC2) • Java 11+ • Maven • Apache Tomcat Example (Amazon Linux 2): sudo yum install java-11-openjdk maven git -y
Download and extract Tomcat: wget https://downloads.apache.org/tomcat/tomcat-9/v9.0.91/bin/apache-tomcat-9.0.91.tar.gz tar -xvzf apache-tomcat-9.0.91.tar.gz sudo mv apache-tomcat-9.0.91 /opt/tomcat chmod +x /opt/tomcat/bin/*.sh

Usage
-
Clone the Repo: git clone https://github.com/danizzy/java-deploy-automation.git cd java-deploy-automation
-
Run Deployment Script: ./deploy.sh dev # For Dev ./deploy.sh test # For Test ./deploy.sh prod # For Prod
-
Access the Application: http://:8080/
Automating with Cron Example: Run Test deployment daily at 1 AM: 0 1 * * * /home/ec2-user/java-deploy-automation/deploy.sh test >> /var/log/deploy_test_cron.log 2>&1
Jenkins Integration
Example Jenkins Pipeline (Jenkinsfile):
pipeline { agent any stages { stage('Checkout') { steps { git 'https://github.com/danizzy/java-deploy-automation.git' } } stage('Deploy to Dev') { steps { sh './deploy.sh dev' } } stage('Deploy to Test') { steps { sh './deploy.sh test' } } stage('Deploy to Prod') { steps { input "Deploy to Production?" sh './deploy.sh prod' } } } }
Future Improvements • Rollback support (restore last working WAR if deployment fails) • Dockerize Tomcat + Maven for container-based deployment • Extend pipeline with AWS services (EC2, S3, CodeDeploy)
Learning Outcomes • Bash scripting for automation • Maven build management • Tomcat application server deployment • Scheduling with cron • CI/CD concepts with Jenkins
