Automate Gitee Project Builds with Jenkins, Maven, and Shell Scripts

1. Jenkins Overview

Jenkins is an open‑source Java‑based continuous‑integration server that automates repetitive development tasks.

2. Environment Preparation

Required tools: JDK, Git, Maven, and Jenkins.

JDK

Git

Maven

Jenkins (installed with the following commands)

sudo wget -O /etc/yum.repos.d/jenkins.repo http://pkg.jenkins-ci.org/redhat/jenkins.repo
sudo rpm --import https://jenkins-ci.org/redhat/jenkins-ci.org.key
sudo yum install jenkins
service jenkins start
vi /var/lib/jenkins/secrets/initialAdminPassword

3. Jenkins Plugin Configuration

Install the recommended plugins on first start, and additionally add Maven and Git plugins if needed.

4. Project Configuration

4.1 Create a Freestyle Project

Create a new freestyle job, give it a name, and save.

4.2 Parameterized Build

jar_path – workspace path for the built JAR

spring_profile – profile name (dev, test, prod)

jar_name – name of the JAR file

project_name – name of the project

4.3 Git Settings

Configure the repository URL and credentials to clone the project from Gitee.

4.4 Build Step (Shell)

mvn clean install -Dmaven.test.skip=true
echo $spring_profile $jar_path $jar_name
cd /usr/local/shell/
./stop.sh $jar_name
echo "Execute shell Finish"
./startup.sh $spring_profile $jar_path $jar_name $project_name

stop.sh (stops the running JAR) and startup.sh (starts the JAR with the selected profile) are used:

jar_name=${1}
echo "Stopping ${jar_name}"
pid=$(ps -ef | grep ${jar_name} | grep -v grep | awk '{print $2}')
if [ -n "${pid}" ]; then
  echo "kill -9 pid: ${pid}"
  kill -9 ${pid}
fi

spring_profile=${1}
jar_path=${2}
jar_name=${3}
project_name=${4}
cd ${jar_path}/${project_name}/target/
nohup java -jar ${jar_name} --spring.profiles.active=${spring_profile} &

5. Test Run

Run the job, adjust parameters if needed, and ensure Maven is reachable by linking it to /usr/bin:

ln -s /usr/local/apache-maven-3.5.4/bin/mvn /usr/bin/mvn

6. Summary

The process involves several pitfalls, but following the steps above allows Jenkins to clone, build, and launch a Spring Boot application automatically.
