Hi, 

I configured the Jira Plugin in our Jenkins instance. Created a basic free style Jenkins job, setup post-build actions Jira: Create issue and was able to successfully verify a used case "Create Jira issue on Build Failure through Jenkins" on April 28th 2021 . Please see the log below: 

+ write Hello World
/tmp/jenkins7340580964673503742.sh: 2: /tmp/jenkins7340580964673503742.sh: write: not found  Build step 'Execute shell' marked build as failure
Build failed, created Jira issue CMTPS-2
Finished: FAILURE

However, I have created a similar job today and it appears to me that the post-build action is not working anymore. 

+ write Hello World
/tmp/jenkins15776115465421610461.sh: 2: /tmp/jenkins15776115465421610461.sh: write: not found   Build step 'Execute shell' marked build as failure
Finished: FAILURE

Also, when creating a new job and adding a post-build action "Jira: Create issue" the issue priority and issue type drop down is not populated anymore.

I have verified the connectivity by clicking the  "Validate Settings" button in the Jira plugin settings and it has shown as "Success".

Please advise. 

Thanks!
