get Jenkins instance from bare groovy

Question

I'm trying to calling Jenkins API from bare groovy script ( in local environment ) instead of https://jenkins.domain.com/script.

Now I can successful import Jenkins libs as below:

@GrabResolver(name='jenkins', root='https://repo.jenkins-ci.org/releases')
@Grab(group='org.jenkins-ci.main', module='jenkins-core', version='2.377')
@Grab(group='org.jenkins-ci.plugins.workflow', module='workflow-api', version='1200.v8005c684b_a_c6')
@Grab(group='org.jenkins-ci.plugins.workflow', module='workflow-job', version='1254.v3f64639b_11dd')
@Grab(group='org.jenkins-ci.plugins.workflow', module='workflow-step-api', version='639.v6eca_cd8c04a_a_')

import jenkins.model.Jenkins
import hudson.Util
import hudson.model.Job
import org.jenkinsci.plugins.workflow.job.WorkflowJob

String rootUrl  = 'https://my.jenkins.com'
String username = 'admin'
String password = 'admin'

// .. how to new a Jenkins instance here ..
// i.e.: Jenkins jenkins = new Jenkins.instance( url, username, password )

// list all workflowjobs
Jenkins.instance.getAllItems( WorkflowJob.class ).collect { it.fullName }

I'd like to know how I can new a jenkins instance by using url similar to run jenkins.model.Jenkins.instance.xxx

btw, I've tried the java-client-api as below, however it cannot identify AbstractItem.class, WorkflowJob.class, etc... is there any solution to "convert" com.offbytwo.jenkins.JenkinsServer to jenkins.model.Jenkins ?

@GrabResolver(name='jenkins', root='https://repo.jenkins-ci.org/releases')
@Grab(group='org.jenkins-ci.main', module='jenkins-core', version='2.377')
@Grab(group='com.offbytwo.jenkins', module='jenkins-client', version='0.3.8')

import com.offbytwo.jenkins.JenkinsServer

String rootUrl  = 'https://my.jenkins.com'
String username = 'admin'
String password = 'admin'

JenkinsServer jenkins = new JenkinsServer( new URI(rootUrl), username, password )
jenkins.getJobs()

the solution is kinda off topic. however it indeed execute the groovy script locally.

by using api

$ SERVER='localhost'
$ COOKIEJAR="$(mktemp)"
# get crumb issue
$ CRUMB=$(curl -u "admin:admin" \
               --cookie-jar "${COOKIEJAR}" \
               "https://${SERVER}/crumbIssuer/api/json" |
               jq -r '[.crumbRequestField, .crumb] | join(":")'
         )

# execute /path/to/script.groovy
$ curl -u "admin:admin" \
       --cookie "${COOKIEJAR}" \
       -H "${CRUMB}" \
       -d "script=$(< /path/to/script.groovy)" \
       https://${SERVER}/scriptText

by using cli

after setup the environment

execute /path/to/script.groovy:

$ ssh -l <username> -p <port> -i <identityFile> ${SERVER} groovy =< ./path/to/script.groovy

if setup ~/.ssh/config, it will be simpler as:

$ ssh ${SERVER} groovy =< /path/to/script.groovy

i.e.:
