This article shows how to add an external script to your server.

External scripts are groovy scripts/classes which can be reused in the connections. For instance, by deploying the following class, you are able to use the code in the incoming and outgoing processors:

class HelloWorld {
      public static void greetings() {
             return "Hello World"
      }

}

This can be used by adding the following script in the processor:

...
issue.description = HelloWorld.greetings()
...

Which sets the description to 'Hello World'.

How to Deploy

Custom scripts can only be deployed on Jira Server/Datacenter and nodes which are deployed through the docker deployment approach.
