Jenkins withCredentials in dynamic selected parameters - jenkins

Question

could you help me with a litle throuble?
I tried find solution with jenkins and your wonderful plugin: uno-choice, but I couldn't it.
I have very simple script:
#!/usr/bin/env groovy
def sout = new StringBuffer(), serr = new StringBuffer()
def proc ='/var/lib/jenkins/script.sh location'.execute()
proc.consumeProcessOutput(sout, serr)
proc.waitForOrKill(1000)
def credential(name) {
def v;
withCredentials([[$class: 'UsernamePasswordMultiBinding', credentialsId: name, usernameVariable: 'USERNAME', passwordVariable: 'PASSWORD']]) {
v = "${env.USERNAME}"
}
return v
}
def key = credential('aws_prod_api')
String str = sout.toString()
String s = str.trim()
String[] items = s.split(",");
def v1 = Arrays.asList(items)
return v1
In general I want get AWS Credentional which save in Jenkins from bash script and with it do something.
I want use withCredentials in block which make selected list, but I don't understand how I can do it.
Could you help me with it?
I will very appreciate it
I tried using withCredentials inside groovy, but I got error:
Fallback to default script... groovy.lang.MissingMethodException: No
signature of method: Script1.withCredentials() is applicable for
argument types: (java.util.ArrayList, Script1$_credential_closure1)

It's because withCredentials does not exist in the scope of Script1. It exists in the scope of the Jenkinsfile DSL. You need to pass it in.
I suggest converting your script to functions. Then passing the Jenkinsfile DSL through to your Groovy code.
def doAwsStuff(dsl) {
...
def key = credential(dsl, 'aws_prod_api')
...
}
def credential(dsl, name) {
def v;
dsl.withCredentials([[$class: 'UsernamePasswordMultiBinding', credentialsId: name, usernameVariable: 'USERNAME', passwordVariable: 'PASSWORD']]) {
v = "${env.USERNAME}"
}
return v
}
and then call it from your Jenkinsfile with:
def result = MyAwsStuff.doAwsStuff(this)
