How can I add a custom button on the Jira Ticket screen?

[Koji Yokohama]

Hi People,

Is it possible to create or add custom button on the Jira Ticket screen for the following scenario:

We have field called "Variant" which is Multiple Select drop down. The variant should be selected from a list include all the variants our system supported. 

Now we wanted to have one button "Yokoten" on the Jira ticket screen - This button should be always shown to the users on the screen regardless the status of workflow. When yokoten button is clicked the following changes should happen.

• Scenario 1: if variant is empty,  nothing will happen. Basically varaint should not be empty, at least as a ticket creation the original variant should be input
• Scenario 2: if variant is added,  search all the linked tickets with the same title and type, create the new ticket in related project with the same title and add the related link to the original ticket, 
• Scenario 3: if variant is deleted, search all the linked tickets with the same title and type, the related ticket will be set to reject and notify to all the watcher 
• Scenario 4: if variant is added, if the ticket status is rejected, then create a new ticket.

Is it possible to include these 4 scenarios? If yes how can we proceed.

Thanks in advance,

@Koji Yokohama if you are using a Jira server/data center, then this can be doable with workflow transition and Scriptrunner post-function.

• create a transition from any status to itself, which will be displayed all the time
• add opsbar-sequence=0 as a property so that it would stay as a Transition button and not as a Dropdown
• add post function using scriptrunner or any relevant add-on which helps to create Jira tickets through the post function.
  • here you will have to apply some groovy scripting if you have scriptrunner on your Jira instance
  • This can help you to get linked tickets  Solved: Scriptrunner - getting linked issues (atlassian.com)
  • This can help you to create tickets Solved: How to create new Issue in Jira Plugin ? (atlassian.com)

I hope this can help, please try.

Thank You @Vedant Kulkarni_Trundl 

Remaining scenarios, will check with scripting.
