How to run jenkins job from groovy script

Question

is it possible to run jenkins job from groovy script?

I know it is possible to run jenkins job from pipeline like this

build job: 'test'

this also doesn't work

build('test')

error for

build job: 'test'

    Caught: groovy.lang.MissingMethodException: No signature of method: hudson8298793087824999032.build() is applicable for argument types: (LinkedHashMap) values: [[job:test]]
Possible solutions: find(), find(groovy.lang.Closure), wait(), run(), run(), dump()

After edit Execute system Groovy script and added

def currentBuild = Thread.currentThread().executable
def job = hudson.model.Hudson.instance.getJob("jobname")
println(job)
def params = new StringParameterValue('version', '1.0.0')  
println(params)
def params1 = new StringParameterValue('target', "dev")  
println(params1)
def paramsAction = new ParametersAction(params, params1) 
println(paramsAction)
def cause = new hudson.model.Cause.UpstreamCause(currentBuild)
println(cause)
def causeAction = new hudson.model.CauseAction(cause) 
println(causeAction)
println('test')
Hudson.instance.queue.schedule(job, 0, causeAction, paramsAction)

I got error on this line Hudson.instance.queue.schedule(job, 0, causeAction, paramsAction)

Build step 'Execute system Groovy script' marked build as failure

Answer 1

For me, I needed the code to run on the master to have quick access to the Jenkins objects and build a job that has the appropriate permissions to send a mail within the information acquired.

I used the build module Execute system Groovy Script to run the script and appended the following code:

// The job you want to run from groovy
def job = hudson.model.Hudson.instance.getJob("SendEmailJob")

// jobsList is a list of jobs of interest formated as HTML
def body = jobsList

def params = []

params += new StringParameterValue('TO', "<team@example.com>")
params += new StringParameterValue('BODY_AS_HTML', body)
params += new StringParameterValue('SUBJECT', "List of jobs of interest")

def paramsAction = new ParametersAction(params)
def cause = new hudson.model.Cause.UpstreamCause(build)
def causeAction = new hudson.model.CauseAction(cause)
hudson.model.Hudson.instance.queue.schedule(job, 0, causeAction, paramsAction)
