URI basepath

[gsingers]

I frequently use the Apache Soft. Foundation JIRA and it's REST endpoint is at https://issues.apache.org/jira/rest/api/

AFAICT, there is no way to construct JiraApi to match this since the basepath is hardcoded.

I ran into an similar issue. I submitted a PR #108 as a work around. I also have a fork with it implemented if you want to try that out.
