[FIXED] How to change Email-ext plugin to load script from custom location

Issue

I like to commit my Jenkins email script to my working copy and use it with Email-ext.

So I wrote something like :

pipeline {
    agent any
    stages {
        stage('Build') {
            steps {
                echo 'Building...'
            }
        }
    }
    post {
        always {
            echo 'Sending email...'
            emailext body: '''${SCRIPT, template="${WORKSPACE}\\Src\\Scripts\\Jenkins\\groovy-html2.template"}''',
            mimeType: 'text/html',
            subject: "[Leeroy Jenkins] ${currentBuild.fullDisplayName}",
            to: "[email protected]",
            replyTo: "[email protected]",
            recipientProviders: [[$class: 'CulpritsRecipientProvider']]
        }
    }
}

But I get the following mail: Groovy Template file [${WORKSPACE}SrcScriptsJenkinsgroovy-html2.template] was not found in $JENKINS_HOME/email-templates.

Solution

Solve it by manually overriding the file using command line:

pipeline {
    agent any
    stages {
        stage('Build') {
            steps {
                echo 'Building...'
            }
        }
    }
    post {
        always {
            echo 'Sending email...'

            bat "copy /Y ${WORKSPACE}\\Src\\Scripts\\Jenkins\\groovy-html2.template \"${JENKINS_HOME}\\email-templates\\groovy-html2.template\""

            emailext body: '''${SCRIPT, template="${WORKSPACE}\\Src\\Scripts\\Jenkins\\groovy-html2.template"}''',
            mimeType: 'text/html',
            subject: "[Leeroy Jenkins] ${currentBuild.fullDisplayName}",
            to: "[email protected]",
            replyTo: "[email protected]",
            recipientProviders: [[$class: 'CulpritsRecipientProvider']]
        }
    }
}

A bit crude, but it works.
