How to set PATH in Jenkins Declarative Pipeline

Question

In Jenkins scripted pipeline you can set PATH env variable like this :

node {
   git url: \'https://github.com/jglick/simple-maven-project-with-tests.git\'
          


        

Answer 1

It is possible with environment section:

pipeline {
  agent { label 'docker' }
  environment {
    PATH = "/hot/new/bin:$PATH"
  }
  stages {
    stage ('build') {
      steps {
        echo "PATH is: $PATH"
      }
    }
  }
}

See this answer for info.

Answer 2

As a workaround, you can define an environment variable and use it in the sh step:

pipeline {
    environment {
        MAVEN_HOME = tool('M3')
    }

    stages {
        stage(Maven') {
           sh '${MAVEN_HOME}/bin/mvn -B verify'
        }
    }
}

Answer 3

Check the following link, this explains how to configure your tools. Using the declarative pipeline things become a bit different but overall it is easier to understand.

Answer 4

Using the tool section in pipeline is only allowed for pre-installed Global Tools. Some tools are provided by plugins, but if it not exists I'am afraid you cannot use the environment setup via pipeline tool declaration.

I hope to be wrong!
