Adding existing Jobs to a MultiJob - jenkins

Question

The Jenkins Job DSL plugin (version 1.42) allows defining MultiJobs:
multiJob('MyMultiJob'){
steps{
phase('First')
phaseJob('JobA'){
#job configuration
}
}
}
}
Is it possible to define a job and add it to a MultiJob in separate steps like in the following example?
jobA = job('JobA')
multiJob('MyMultiJob'){
steps{
phase('First')
jobA
}
}
}
Being forced to define many different jobs inside the MultiJob definition seems complicated and adds a lot of complexity. Are there workarounds? Is it possible to move the definition of a phase job to a function outside the MultiJob definition?

Answer 1

You can do this
def j= {
parameters {
propertiesFile('my1.properties')
}
}
multiJob('example') {
steps {
phase('First') {
phaseJob('JobZ', j)
}
phase('Second') {
phaseJob('JobA', j)
phaseJob('JobB')
phaseJob('JobC')
}
}
}
Which you can use 'j'. The closure syntax outside the parameters is syntactic sugar and the method call assumes the closure is in fact the last parameter
