I am running Jenkins 2. I am trying to build from a Jenkinsfile

The existing custom tools plugin is not compatiable with pipeline

tony_murphy: fixing Custom Tools plugin looks feasible, though not trivial: https://github.com/jenkinsci/pipeline-plugin/blob/master/DEVGUIDE.md

#build-wrappers would need to make the `LauncherDecorator` be safely `Serializable`

#!groovy

node {

    wrap([$class: 'AnsiColorBuildWrapper', colorMapName: 'xterm']) {
        stage 'compile'

        def activatorHome  = tool "activator-1.3.x"

        stage name: 'package', concurrency: 1
        sh "${activatorHome}/activator debian:package-bin"
    }
}
