JIRA Groovy Script - Check on duplicate sub-tasks - groovy

Question

The code below creates 3 sub-tasks for each Version selected in SW Version custom field. This is placed on a workflow transition as a post function and works perfectly. However, if the workflow transition is revisited it creates duplicate subtasks for the already selected versions.
Example:
SW Version field has 5 options:
1, 2, 3, 4, 5
if a user selected 1 and 2 and proceeds with the transition, it will create 6 subtasks 3 for each version selected. (All good here)
if the user updates the SW Version field to 1, 2 , 3, and 4 which already has 1 and 2 pre-selected, it will create 12 additional subtasks making the total 18 with 6 duplicates of 1 and 2.
I wanted to put a check on these duplicates, so basic logic is if the subtask already exist go to the next one. Something like for each version selected, check if subtasks already exist and proceed. I tried doing it various ways and failed. Have commented out some codes below to get summary of the subtasks and compare with all existing subtasks summary but it doesn't work.
In addition I tried doing this to no avail.
if(issue.getSubTaskObjects()*.summary.equals(summaryText)){
log.info("Subtask already exists")
return;
Any help would be greatly appreciated !

It's not working just because issue.getSubTaskObjects()*.summary return array and then you try compare this array with string in .equals(summaryText). But you was close and if change this part to issue.getSubTaskObjects()*.summary.contains(summaryText) (mean you search summaryText in each array element) it will be work pretty well.
Also in my opinion next code will be more understandable and clear issue.getSubTaskObjects().find{it.getSummary() == summaryText} (this also will be work inside if statement)
