Getting YAML value from a variable Groovy-CodePudding

I have a YAML file with this structure

key1: value 1 
key2:
  - value 21
  - value 22
key3:
  - key31: value 311
    key32: value 321
    key33: value 331

And I need to access value 331, so I have this code:

@Grab('org.yaml:snakeyaml:1.26')
import org.yaml.snakeyaml.Yaml

 // parse the yaml 
def yaml = new Yaml().load(new FileReader("file.yaml"))
def var1 = "key3"
def var2 = "key33"

println yaml.key3.key33 // this is getting value 331
println yaml.$var1.$var2 // this is getting null

Is there any other way to get this value with given variables?

Note this is part of a Jenkins pipeline.

Thank you so much.

CodePudding user response：

This should work for you. You can simply use readYaml step to read the YAML file within the Jenkins Pipeline

def yaml = readYaml file: 'file.yaml'                

def var1 = "key3"
def var2 = "key33"
println yaml.key3.key33 
println yaml."$var1"."$var2"

As you can see above I have surrounded your dynamic variables with double quotes, which will tell Jenkins to interpolate them.
