Spring Boot Microservices - Jenkinsfile "The goal you specified requires a project to execute but there is no POM in this directory"

Question

I have a problem about running Jenkinsfile in Jenkins for my Spring Boot Microservices example.

I run Jenkins on Docker.

After implementing a required settings for Jenkins and creating Jenkinsfile in my Spring Boot Microservices example, I run the pipeline in Jenkins but I got an error.

Here is the error message shown below.

+ mvn clean install -D skipTests

Answer 1

In your repo (https://github.com/Rapter1990/springbootmicroservicedailybuffer ) you have several pom.xml, but they are in subfolders, so you should enter them before running maven.

dir("apigateway") {
  sh "mvn clean install -DskipTests"
}
dir("auth-service") {
  sh "mvn clean install -DskipTests"
}
...

I also guess you could delete the "git" line in your Jenkinsfile, as Jenkins is already downloading the project to run it (you have your jenkinsfile and your source code in the same git repo)

Here is the answer shown below.

pipeline {
    agent any
    tools {
        maven "Maven 3.6.3"
    }
    stages {
        stage("build project") {
            steps {
                // git 'https://github.com/Rapter1990/springbootmicroservicedailybuffer'
                echo "Java VERSION"
                sh 'java --version'
                echo "Maven VERSION"
                sh 'mvn --version'
                echo 'building project...'

                dir("service-registry") {
                  sh "mvn clean install"
                }

                dir("configserver") {
                  sh "mvn clean install"
                }

                dir("apigateway") {
                  sh "mvn clean install -DskipTests"
                }

                dir("auth-service") {
                  sh "mvn clean install -DskipTests"
                }

                dir("productservice") {
                  sh "mvn clean install -DskipTests"
                }

                dir("orderservice") {
                  sh "mvn clean install -DskipTests"
                }

                dir("paymentservice") {
                  sh "mvn clean install -DskipTests"
                }
            }
        }
    }
