Not able to split string in groovy DSL and there is no multi-line

I am trying to split a URL http://localhost:8081/artifactory/api/storage/myrepo/sub1/file.zip in groovy DSL of Jenkins. It is a single line string. But following code does not work

String[] arr= string_var.split('/');  
String[] arr=string_var.split('\\/');

It does not split it and returns itself in arr[0]. I am not sure if it is a bug. Please let me know if any other way is there in groovy to get "sub1" from URL string.

Are you sure that you doing DSL script correctly? As the groovy code looks to be OK. Try to skip declaring types

def url_str = 'http://localhost:8081/artifactory/api/storage/myrepo/sub1/file.zip'
def sub = url_str.split('/')[-2]
println(sub)

in one line:

println('http://localhost:8081/artifactory/api/storage/myrepo/sub1/file.zip'.split('/')[-2])

no split, indexes:

def url_str = 'http://localhost:8081/artifactory/api/storage/myrepo/sub1/file.zip'
int[] indexes = url_str.findIndexValues {it == "/"}
println url_str.substring(indexes[-2] + 1, indexes[-1])

Try enclosing your code inside a 'script' tag of DSL language like the following piece of code:

pipeline {
  agent any
  stages {
    stage('Test') {
      steps {
        script {
          def string_var = "http://localhost:8081/artifactory/api/storage/myrepo/sub1/file.zip"
          String[] arr= string_var.split('/');
          println "${arr[0]}"
        }
      }
    }
  }
}

Executing code above I get this result on the console:

[Pipeline] {
[Pipeline] stage
[Pipeline] { (Test)
[Pipeline] script
[Pipeline] {
[Pipeline] echo
http:
[Pipeline] }
[Pipeline] // script
[Pipeline] }
[Pipeline] // stage
[Pipeline] }
[Pipeline] // node
[Pipeline] End of Pipeline

Thus, giving the expected 'http:' String

Another Groovy way to get the string 'sub1' (regex):

String s = "http://localhost:8081/artifactory/api/storage/myrepo/sub1/file.zip"

def match = s =~ /(sub1)/
if (match.size() > 0) { // If url 's' contains the expected string 'sub1'
  println match[0][1]
  // Or do something with the match
}​
