How to get the status of a particular stage in a pipeline

How do we get the status of the preceding stage(s) in a Jenkins pipeline. For example: My example pipeline is as under:

pipeline {
    agent
    {
        node {
                label 'master'
                customWorkspace "${env.JobPath}"
              }
    }

    stages 
    {
        stage('Start') {
            steps {
                sh 'ls'
            }
        }

        stage ('set_env') {
            steps {
                // script to set environment.
            }
        }

        stage ('Build') {
            steps {
                // script to build.
            }
        }

        stage ('Send_mail') {
            steps {
                // script to send mail.
            }
        }

        stage('End') {
            steps {
                sh 'ls'
            }
        }
    }
}

How can i get the status of a particular stage in a pipeline. for ex: i want to take certain decisions based on whether the "Build" stage was a success or a failure.

Is there any environment variable which tracks the status of every stage, or there's a Jenkins REST API which can help me achieve this.

Thanks!

Jenkins declarative pipelines are opinionated syntax on top of the former jenkins pipeline approach. This means you can also regard a jenkins declarative pipeline as a groovy script with extra syntactic sugar. So you can freely use variables. As mentioned in my comment above, you can set the whole jobs status via currentBuild.result, but if you want to make decisions within the same job between stages: simply use groovy variables to indicate the state of the previous stage. Taking your example:

pipeline {

    def didSucceed = true

    agent
    {
        node {
                label 'master'
                customWorkspace "${env.JobPath}"
              }
    }

    stages 
    {
        stage('Start') {
            steps {
                sh 'ls'
            }
        }

        stage ('set_env') {
            steps {
                // script to set environment.
                didSucceed = true // Here you indicate whether stuff actually worked..
            }
        }

        stage ('Build') {
            steps {
                if (didSucceed) {
                    // script to build.
                } else {
                    // Procedure in case of previous error..
                }
            }
        }

        stage ('Send_mail') {
            steps {
                // script to send mail.
            }
        }

        stage('End') {
            steps {
                sh 'ls'
            }
        }
    }
}

You could also stay in a more declarative way using the when statement in combination with a boolean variable.
