How to let jenkins know my service was restart success of fail - jenkins

Question

I have a spring boot application on centos server and use a shell file to restart it.
jenkins version: docker run -dp 8080:8080 --name jenkins jenkinsci/blueocean
start-service.sh
#!/bin/bash
sudo systemctl restart sb
In my Jenkinsfile i upload jar file to server and execute the start-service.sh, but jenkins seem dosen't know my java application restart success or fail.
Jenkinsfile
pipeline {
agent none
stages {
stage('Build') {
agent {
docker {
image 'maven:3-alpine'
args '-v /root/.m2:/root/.m2'
}
}
steps {
sh 'mvn -B -DskipTests clean package'
sh 'mvn help:evaluate -Dexpression=project.name | grep "^[^\\[]" > project-name'
sh 'mvn help:evaluate -Dexpression=project.version | grep "^[^\\[]" > project-ver'
}
}
stage('Deploy') {
agent any
environment {
HOST = "${HEHU_HOST}"
USER = "yunwei"
DIR = "/www/java/sb-demo"
VERSION_FILE = "${DIR}/version"
CMD_SERVICE = "${DIR}/start-service.sh"
}
steps {
sshagent (credentials: ['hehu']) {
sh '''
name=$(cat project-name)
ver=$(cat project-ver)
jarFile=${name}-${ver}.jar
scp target/${jarFile} ${USER}#${HOST}:${DIR}/${jarFile}
scp project-ver ${USER}#${HOST}:${VERSION_FILE}
ssh -o StrictHostKeyChecking=no -l ${USER} ${HOST} -a ${CMD_SERVICE}
'''
}
}
}
}
}
I deliberately let Java application go wrong, and systemctl restart is fail but jenkins stage is success.
#SpringBootApplication
#RestController
public class Application {
public static void main(String[] args) {
throw new RuntimeException("Test error");
// SpringApplication.run(Application.class, args);
}
#GetMapping("/test")
String test() {
return "furukawa nagisa\n";
}
}
Try Daniel Taub solution get syntax error.
pipeline {
agent none
stages {
stage('Hello') {
agent any
steps {
sshagent (credentials: ['hehu']) {
SH_SUCCESS = sh(
script: '''
ssh -o StrictHostKeyChecking=no -l yunwei ${HEHU_HOST} -a /www/java/sb-demo/start-service.sh
''',
returnStatus: true
) == 0
echo '${SH_SUCCESS}'
}
}
}
}
}

You can get the sh returned exit status code and fail the build manually if its error status.
For checking your exit code, Jenkins support it that way
returnStatus (optional)
Normally, a script which exits with a nonzero status code will cause the step to fail with an exception. If this option is checked, the return value of the step will instead be the status code. You may then compare it to zero, for example.
script {
SH_SUCCESS = sh (
script: "your command",
returnStatus: true
) == 0
}
To manually fail the build you have couple of options:
error('Fail my build!')
Or alternatively
currentBuild.result = 'FAILURE'
return
