Concurrent Updates in Jenkins Pipeline Affecting Jira Issue Versions

I’m encountering a situation where my Jenkins pipeline utilizes a script that interacts with Jira to update issue versions. The code essentially performs the following actions:

node {
    stage('JIRA') {
        def searchResults = jiraJqlSearch jql: "project = ${jiraProjectKey} AND issuekey = ${issueKey}"
        def issues = searchResults.data.issues
        for (index = 0; index < issues.size(); index++) {
            def retrievedIssue = jiraGetIssue idOrKey: issues[index].key
            def createdVersion = jiraNewVersion version: [name: "${newVersion}", project: "${jiraProjectKey}"]
            def updatedFixVersions = retrievedIssue.data.fields.fixVersions << createdVersion.data
            def issueUpdate = [fields: [fixVersions: updatedFixVersions]]
            response = jiraEditIssue idOrKey: issues[index].key, issue: issueUpdate
        }
    }
}

The script successfully searches and appends new versions to issues. However, I face a problem when multiple concurrent builds attempt to update the same Jira issue with different versions. This often results in some builds overwriting others, leading to the loss of previously appended versions. For instance:

  • Job 1 - build 1 updates ${issueKey} with fixVersion 1.1
  • Job 2 - build 1 updates ${issueKey} with fixVersion 2.1
  • Job 3 - build 1 updates ${issueKey} with fixVersion 3.1

Eventually, the final state of ${issueKey} may show fixVersions as 1.1 and 3.1, with version 2.1 missing from the activity history. I believe this might be related to a Dirty Write issue within either Jira or the Jenkins plugin. Could someone suggest modifications to the pipeline script that would allow independent executions to correctly append to fixVersions without causing loss of data? Additionally, I’m working on a standalone job to replicate this issue for better testing of potential solutions. Thank you for your help.

I’ve encountered similar issues while working with parallel updates in Jira. A potential solution is to implement an optimistic locking mechanism. Before making any updates, you could retrieve the current state of the issue’s fixVersions, append the new version, and then perform a check just before writing back to ensure no other concurrent process has modified the list in the interim. If a conflict is detected, you should retry the update. This approach can mitigate the dirty write issue by ensuring you always start your update from the most recent state. Additionally, logging the updates and results of the optimistic lock checks can be invaluable for troubleshooting race conditions when multiple builds are updating simultaneously.
