falcon I am wondering about the real use case here, not sure if this change really is going to behave as expected especially when using multiple sites with in a single run, the environment variable would change consistently based on the site. 

My use case is on the description : build links to issues, using configuration instead of a remote call to obtain the root URL of the Jira site.

To preserve multi sites runs, we can limit this change to the case where the

JIRA_SITE

env var is set.

falcon If that is the case, I would use the script to get the site url from the config. You would need to approve some signatures (script security) to use the below methods, and fine tune it a bit as it can throw null pointer exception when site not not available for given name. Let me know if you still need it as an environment variable.

import org.thoughtslive.jenkins.plugins.jira.Config;
import org.thoughtslive.jenkins.plugins.jira.Site;

println getJIRASiteURL("Test")

def getJIRASiteURL(siteName) {
    Site[] sites = Config.DESCRIPTOR.getSites()
    return sites.find { it.name == siteName }.url.toString()
}

Thanks nrayapati, your script works for me, I did not think about this way to go
