Issue in pipeline step of jenkinsfile

[spratap singh]

registeries = [1,2,3,4] 

 Map tasks = [:]

 for (j=0;j<=registeries.size();j++) 

{ 

 tasks["Code ${j}"] = { -> sh "touch ${j}" }

 } 

 parallel(tasks) 

 sh "ls -lrt"

 

Above code should create files 0,1,2,3,4,5

but the last line ls -lrt only prints 5 which means it is only taking the last iteration value in all values of map tasks

Can anyone tell what I am doing wrong here ?

This is a classic issue that a lot of people run into in various programming languages. https://groovyconsole.appspot.com/script/5078409050849280 shows the same problem and one way to fix it (click "edit in console" and then you can execute the script). This kind of issue is why in Java, anonymous classes and lambda expressions can only reference variables that are final or effectively final.

Hey Devin,

Sorry for the late reply , I was down with covid for some time.

the code that you have given i tried and it works , but how to handle the string parameters ?

some string parameters which I am assigning they are also interfering with each other

You need to add an intermediate var in your first loop and use this in the sh step
