How to parse ArrayList to String, without [] bracket?

[Teja]

Hi,

I wanted to compare my unreleased version with user selected version picker value.

but the problem is when I use this code  

def releaseVerField = ComponentAccessor.customFieldManager.getCustomFieldObjectByName("Target Version")
def releaseVerFieldValue = issue.getCustomFieldValue(releaseVerField)

it retrieves [19.2.8] with bracket, how can cast this List to String.

I am in a real need of help, can anyone with this below code.

Since I am new to groovy so, 

import com.atlassian.jira.ComponentManager
import com.atlassian.jira.project.version.VersionManager
import com.atlassian.jira.component.ComponentAccessor
import com.opensymphony.workflow.InvalidInputException;
import com.atlassian.jira.issue.Issue;
import com.atlassian.jira.project.ProjectImpl

ComponentManager componentManager = ComponentManager.getInstance()

VersionManager versionManager = ComponentAccessor.getVersionManager();
def releaseVerField = ComponentAccessor.customFieldManager.getCustomFieldObjectByName("Target Version")
def releaseVerFieldValue = issue.getCustomFieldValue(releaseVerField)
log.warn(releaseVerFieldValue)

List<VersionManager> versions=versionManager.getVersionsUnreleased(10207,true) as List
def tarversion= versions.iterator().next().toString()

if (releaseVerFieldValue !=tarversion)
{
log.warn(versions.iterator().next())
return true

}
else
throw newInvalidInputException("Target version must be unreleased");

Output:

Thanks & Regards

You can assign your List to a String, and the necessary casting will be performed. You can then use a function that I wrote for this exact purpose to strip the brackets.

e.g.

String releaseVerFieldValueStr = releaseVerFieldValue
releaseVerFieldValueStr = stripBrackets(releaseVerFieldValueStr)

def stripBrackets(String str){
 String retStr = str
 if(str == null || str.length() < 2)
 {
  return str
 }
 if(retStr.substring(0,1).equals("[")){
  retStr = retStr.substring(1)
 }
 if(retStr.substring(retStr.length()-1).equals("]")){
  retStr = retStr.substring(0,retStr.length()-1)
 }
 return retStr
}

Hi @Payne How can we write this groovy code to Java code?
