Hi,
I have followed your tutorial
https://developer.atlassian.com/jiradev/jira-platform/guides/fields/tutorial-custom-fields-in-jira
To develop a custom field plugin.
It does not work anymore presumably because this was for an earlier version of Jira.
Errors include things such as getStringFromSIngularObject is no longer in AbstractSingleFieldType so @Override is not valid.
The end result is that I can get it to compile without errors, and the plugin is shown as enabled when doing atlas-run, but the custom field never appears when I go to select "Add Custom Field", and select "Advanced".
Do you have a working version of some code?
