Delete a user with issue comments

[Name]

Hello!

I'm trying to delete all comments from specific user in project

import org.ofbiz.core.entity.GenericValue;
import com.atlassian.jira.component.ComponentAccessor;
import com.atlassian.jira.ComponentManager;
import com.atlassian.jira.issue.Issue;
import com.atlassian.jira.issue.IssueManager;
import com.atlassian.jira.project.Project;
import com.atlassian.jira.project.ProjectManager;
import com.atlassian.jira.issue.MutableIssue;
import com.atlassian.jira.issue.comments.Comment;
import com.atlassian.jira.issue.comments.CommentManager

import java.awt.List;
ProjectManager projectManager = ComponentAccessor.projectManager
Project proj= projectManager.getProjectByCurrentKey("CW")
CommentManager commentManager = ComponentAccessor.commentManager
IssueManager issueManager = ComponentAccessor.issueManager
for (GenericValue issueValue: issueManager.getProjectIssues(proj.getGenericValue())){
    String id = 'CW-' + issueValue.number
    
    //Issue issue = issueManager.getIssueObject(issueValue)
    MutableIssue missue = issueManager.getIssueObject(id)
    List<Comment> comments = commentManager.getComments(missue) as List
    comments.each { Comment comment ->
        if (comment.getAuthorApplicationUser() == '222') {
            commentManager.delete(comment)
        }
    }
} 

But have no results. Any ideas? 

Thanks for help!

Here's how you do it:

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.issue.IssueManager
import com.atlassian.jira.issue.comments.Comment
import com.atlassian.jira.issue.comments.CommentManager
import com.atlassian.jira.project.Project
import com.atlassian.jira.user.ApplicationUser

Project project = ComponentAccessor.getProjectManager().getProjectByCurrentKey("ABC")
IssueManager issueManager = ComponentAccessor.getIssueManager()
CommentManager commentManager = ComponentAccessor.getCommentManager()

Collection<Issue> issues = issueManager.getIssueIdsForProject(project.getId()).collect{issueManager.getIssueObject(it)}

issues.each{issue ->
    List<Comment> userComments = commentManager.getComments(issue).findAll{comment ->
        comment.getAuthorApplicationUser() == getUser("username")
    }
    if(userComments){comment ->
        commentManager.delete(comment, false, getUser("username2"))
    }
}

ApplicationUser getUser(String userName){
    return ComponentAccessor.getUserManager().getUserByName(userName)
}
