generate a entity class for jira

Here's a simple Java class representing a Jira issue entity:

public class JiraIssue {
    private String key;
    private String summary;
    private String description;
    private String assignee;
    private String reporter;
    private String status;
    private List<String> labels;
    private String projectKey;
    private String issueType;
    private Date createdDate;
    private Date updatedDate;
    private Date dueDate;
    private int votes;
    private int watches;
    
    // Constructors, getters and setters, and other methods omitted for brevity
}

This class contains fields for basic information about a Jira issue, such as its key, summary, and description, as well as additional information such as the issue's assignee, reporter, and status. It also includes fields for labels, project key, issue type, and various dates. Finally, it includes fields for the number of votes and watches on the issue.

Of course, this is just a basic example - depending on your specific use case, you may want to include additional fields or methods to handle more complex functionality.
