环境

CentOS Linux release 7.9.2009 (Core)
Jira 8.16.1

描述

在父任务中有许多子任务，创建自定义字段“单行文本”-“子任务的完成百分比”在父任务界面显示。
当子任务完成时，自动更新该字段。

实现

使用 ScriptRunner 中的 Listeners 来实现该功能。
Events：Generic Event

脚本如下：
Github：https://github.com/Shankschn/Jira-Script/blob/main/scriptRunner/auto_calc_update_subtask_pct_field_on_parent

import com.atlassian.jira.issue.Issue
import com.atlassian.jira.issue.ModifiedValue
import com.atlassian.jira.issue.util.DefaultIssueChangeHolder
import com.atlassian.jira.component.ComponentAccessor

def issue = event.issue as Issue
log.warn(issue.key)
log.warn(issue.issueType.name)

if (issue.issueType.name == "子任务") { // 子任务 issue.issueType.name
    
    def issue2 = issue.getParentObject()
    log.warn(issue2.key)
    log.warn(issue2.issueType.name)
    
    if (issue2.issueType.name == "任务") { // 父任务 issue2.issueType.name
        
        issue = issue2
        log.warn(issue2.key)

        def subTaskSum = 0
        issue.getSubTaskObjects()?.each { subtask ->
            subTaskSum += 1
        }

        // customfield_12210 自定义字段
        def tgtField = ComponentAccessor.getCustomFieldManager().getCustomFieldObject("customfield_12210")
        def changeHolder = new DefaultIssueChangeHolder()

        if (subTaskSum != 0) {
            def subTaskOKSum = subTaskSum
            issue.getSubTaskObjects()?.each { subtask ->
                subtask.getResolution() != null ? subTaskOKSum -= 1 : subTaskOKSum 
            }

            String jg = (int) (((subTaskSum-subTaskOKSum) * 100) / subTaskSum)
            jg = jg + "%"

            tgtField.updateValue(null, issue, new ModifiedValue(issue.getCustomFieldValue(tgtField), jg), changeHolder)
        }
    }
}
