IIC, this is a scope problem.
To strictly answer to your question, you could convert the global function
into a Closure
<http://mrhaki.blogspot.fr/2009/08/groovy-goodness-turn-methods-into.html>
and then pass it as parameter of *functionB*.
I think something like that should work :
externalScripts = ''
pipeline {
agent master
stages {
stage('first') {
agent { label 'master' }
steps {
script {
loadScripts()
externalScripts.functionA()
}
}
}
stage('second') {
agent { label 'some_slave_node' }
steps {
script {
externalScripts.functionB(*this.&someGlobalFunction*)
}
}
}
}
}
def someGlobalFunction() {
// some common code
}
def loadScripts() {
externalScripts = load 'script_next_to_jenkinsfile.groovy'
}
// contents of script_next_to_jenkinsfile.groovy
def functionA() {
// Some regular code will work just fine
}
*def functionB(customFunction) {
customFunction()
}*
return this
However, I'm personally not very comfortable to use this kind of syntax
inside Pipeline scripts and IMHO, you should try to find another way to
structure it (to avoid complexity).
BTW, I'm wondering if others have already used this kind of syntax/tricks
inside their pipeline and if it's something that it's not recommended (if
so, why ?).
Hopefully it helps.
Cheers
