Using Jenkins to Clone a Gitee Project, Build with Maven, and Deploy via Shell Scripts

Jenkins is introduced as an open‑source continuous‑integration tool built on Java that automates repetitive deployment tasks.

Environment preparation : The tutorial lists the required tools—JDK, Git, and Maven—and shows how to install Jenkins on a Red Hat‑based system:

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

After starting Jenkins, the user accesses http://${ip}:8080 to complete the initial setup and retrieve the admin password.

Jenkins plugin configuration : It is recommended to accept the default plugin set and additionally install the Maven and Git plugins.

Project configuration : A freestyle job is created with four parameters— jar_path , spring_profile , jar_name , and project_name . The Git repository URL (hosted on Gitee) is configured, and a Shell build step is defined:

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

The stop.sh script locates the running jar process and kills it if found:

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

The startup.sh script changes to the jar directory and launches the application with the selected Spring profile:

cd $jar_path/$project_name/target/
nohup java -jar $jar_name &
BUILD_ID=dontKillMe nohup java -jar $jar_name --spring.profiles.active=$spring_profile &

Test run : After triggering the job, the parameters can be reviewed and modified. An issue where Jenkins could not find the mvn command is resolved by linking the Maven binary to /usr/bin/mvn :

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

The job runs successfully and the deployed Spring Boot application is accessible via the blog URL.

Conclusion : Although the setup involves many small pitfalls, the overall process of using Jenkins to clone a Gitee project, build it with Maven, and manage deployment through shell scripts is achievable and can be refined through further experimentation.
