We can confirm that you can generate a new trial license for yourself directly from the Atlassian Marketplace by following the steps below.
- Navigate to the ScriptRunner for Jira Server /Data Center marketplace listing located here.
- Once on the page navigate to the top right-hand corner of the page and click on the yellow button which says Try It Free.
- When prompted login with your My Atlassian account and select the version of the product that you wish to generate a trial licence for.
- Follow the steps prompted in the wizard to generate the new trial licence.
Please note the maximum number of trial licences that can be generated is 6 to allow the plugin to be trialled for a maximum of 6 months.
If you need to generate a licence for longer than this period then you will need to contact Atlassian directly and ask them to do this as they control all licencing in their systems.
