Kill stuck build

Jenkins.instance.getItemByFullName("<projectName").getBuildByNumber(<BuildNumber).finish(hudson.model.Result.ABORTED, new java.io.IOException("Aborting build"));

Mass disconnect ssh connections timing out

import hudson.slaves.SlaveComputer

Jenkins.instance.computers.each { computer ->

        println "cancelling connect attempt - set timeout to prevent this scenario ${computer.name}"
        computer.doDoDelete();
    }
}

Mass connect agent nodes

Jenkins.instance.nodes.each { node ->
    if (node && node.toComputer().nodeName &&! node.toComputer().online) {
        node.toComputer.connect(false)
        println(node.toComputer().nodeName)
