Your checklist for this issue

🚨 Please review the guidelines for contributing to this repository.

• [x] Jenkins version ==> 2.346.1

• [x] Plugin version ==> 3.7.1

• [x] OS ==> Red Hat Enterprise Linux Server 7.9 (Maipo)

Reproduction steps

• Add a Proxy
• Add the Jira-Server to the "No Proxy Host"-List
• Use the Plugin (we use it to read Versions)

Results

Expected result:

Jira is accesses without the Proxy, since the Jira-Server is on the "No Proxy Host"-List

Actual result:

The Proxy is used to connect to Jira, our Proxy can't resolve the Jira server, and that cause an Error: See this log:

• http://webproxy.mycompany.example.com:8080 is the Proxy server
• http://jira.otherdomain.example.com:8080 is the Jira Server, and jira.otherdomain.example.com is on the "No Proxy Host"-List

Relates to https://github.com/jenkinsci/jira-plugin/issues/385 where the proxy was first used

Hi @hinneLinks, Indeed, that might be caused by the fact that the current implementation is not taking into account the noProxyHost setting.

This should be fairly easy reproducible via a test. Would you have sime time to spend and contribute a Pull Request with a fix? Alternatively, please consider sponsoring one of the maintainers to fix this issue.
