how to install 'OSLC connect for Jira' using descriptor URL

[김승원]

Hi, I am Jira new-bie user

Use-Case:

• Want to do test data connection between Jira and other program(CATIA Magic).
• transform and deliver epic, issue, task into requirement using OSLC

Purpose:

• to do that, I tried installing 'OSLC Connect for Jira' provided below link
  • https://marketplace.atlassian.com/apps/1221984/sodiuswillert-oslc-connect-for-jira?hosting=datacenter&tab=overview

Progress:

• select 'Try it free' in above link
• *.jar had been downloaded
• got key for license
• to install downloaded file to Jira, I clicked 'Upload app' in 'Mange App' as below picture

• then, it required 'descriptor URL' as below picture

Issue:

• However, I couldn't find any information about descriptor URLs anywhere in the jar file I downloaded, and I couldn't find a guide to descriptor URLs on the Solidius homepage.
• So I am not able to install OSLC connect for Jira.

Can anyone help me with this?
