Creating issues broken with JIRA v9

[NaanProphet]

Looks like net.rcarz.jiraclient.JiraClient#createIssue is broken with JIRA version 9.

I found some documentation that outlines why the endpoint has been removed: https://confluence.atlassian.com/jiracore/createmeta-rest-endpoint-to-be-removed-975040986.html

The same article suggests the following solution, which would require rewriting the URI calls that occur in net.rcarz.jiraclient.Issue#getCreateMetadata

Modify the calls the integrations use to the following:

RETURN A LIST OF PROJECTS
/rest/api/2/project 

RETURN A LIST OF ISSUE TYPES GIVEN A PROJECT
/rest/api/2/issue/createmeta/{projectIdOrKey}/issuetypes

RETURN A LIST OF FIELDS GIVEN A PROJECT AND AN ISSUE TYPE
/rest/api/2/issue/createmeta/{projectIdOrKey}/issuetypes/{issueTypeId} 

We have also come across this issue when upgrading between JIRA version 8 and 9.

Our logs show this error, reproduced via curl here

curl -u xxxx:xxxx -X GET -H "Content-Type: application/json" https:/x.x.x/rest/api/2/issue/createmeta

{"errorMessages":["Issue Does Not Exist"],"errors":{}}%

Using

/rest/api/2/issue/createmeta/{projectIdOrKey}/issuetypes/{issueTypeId}

is successful

However as you say the client constructs the issue using the /rest/api/2/issue/createmeta/ endpoint with query params for project and issue type (by name rather than ID) that has now been removed
