This is the documentation of JSU for Jira Cloud. If you are using JSU on Jira Server/Data Center, you can find the documentation here.
'User Is In Any Groups' will verify that the current user is in at least one of the specified groups. You must specify the groups when configuring the check. For example: A workflow is configured so that the 'Resolve' transition has the 'User Is In Any Groups' check. If the user is a developer, and the issue is a Story, a sub task will be created for the QA Analysis. JSU supports many different field types; system fields, as well as custom fields. You should be aware, however, that not all field types or all combinations are supported. We have tried to cover the most important field types but we are continuously adding more and improving how different field types are supported. We recommend you test JSU with fields to see if it is compatible with your system. Our evaluation license provides you with a 30-day free trial. Description
There is a 'User Is In Group' condition in standard JIRA, which only lets you verify the membership of the user against a single group.Configuration
