Groovy - How to remove an element from a list based on its content?

Hamsand

I'm working on a funky script for Jira - I'm collecting a list of comments for an issue and storing the username of the last comment.

example:

import com.atlassian.jira.component.ComponentAccessor
def commentManager = ComponentAccessor.getCommentManager()
def comments = commentManager.getComments(issue)
if (comments) {
comments.last().authorUser
}

Sometimes, I don't want to store the username (if it belongs to a predefined role). Basically, I want to check for comments first, then remove all comments from the list that match my criteria, then by calling last(). authorUser ends. It's just like:

comments.each {
if (it.authorUser.toString().contains(user.toString())) {    
// Here is where I'd want to remove the element from the list**
}
}
comments.last().authorUser  // then store the last element as my most recent comment.

Reasonable? I'm new to Groovy so I totally suspect there are a lot of issues. Most of the examples I've come across involve number checking...a bit difficult.

You can use Collection.removeAll() : it modifies the collection by removing elements that match the passed closure condition.

comments.removeAll {
    it.authorUser.toString().contains(user.toString())
}
comments.last().authorUser
