Jenkins pipeline mvn: command not found - maven

Question

My test is working fine as Maven project. It fetches code from Git.
I wanted to execute the same in Pipeline so I wrote the below script for pipeline project.
pipeline {
agent any
options {
timestamps()
}
stages{
stage('Just Testing') {
steps {
git "https://github.com/myRepo.git"
script{
sh 'mvn test'
}
step([$class : 'Publisher', reportFilenamePattern : "**/testng-results.xml"])
}
}
}
}
But when I execute I am getting mvn: command not found error Java and Maven path is set correctly in global tool configuration (I am sure because I am able to execute other maven projects, only pipeline is failing.)
Console output:

How can I fix this issue?

Answer 1

You don't have any tools declared for your maven project.
This would be a good starting point for running mvn goals from Jenkins.
Declarative maven project.

Answer 2

Following pipeline script did the job for me. unlike maven projects created in jenkins you need to add the maven and java as tool for the script.
MAVEN_HOME - configured in "Managing Jenkins" → "Global Tool Configuration"
JAVA_HOME - configured in "Managing Jenkins" → "Global Tool Configuration"
pipeline {
agent any
tools {
maven 'MAVEN_HOME'
jdk 'JAVA_HOME'
}
stages {
stage ('Build') {
steps {
sh 'mvn -B -ntp -Dmaven.test.failure.ignore verify'
}
}
}
}

Answer 3

In the pipeline script you have to give maven path like
def mvnHome = tool name: 'maven-3.8.6', type: 'maven'
sh "${mvnHome}/bin/mvn package"
in maven stage
I hope it will work because it works for me.. thank you
