如何使用 java 更新 jira 7+ 中的自定义字段

How to update custom field in jira 7+ using java

这个问题的答案在我检查过的所有来源上都已过时或不完整。

这里有一些例子:

How do I save a value into a custom field in JIRA programmatically?

Automating custom field value change in JIRA

Jira: How to obtain the previous value for a custom field in a custom IssueEventListener

CustomFieldManager is not getting the custom field after modifying the custom field name using REST api in jira

我没有足够的声誉来评论这些问题中的任何一个。但是我有一个答案。

所以这是我的决定:

CustomField csUserField = ComponentAccessor.getCustomFieldManager().getCustomFieldObjectByName(fieldName);
IssueService issueService = ComponentAccessor.getIssueService();
IssueInputParameters issueInputParameters = issueService.newIssueInputParameters();
issueInputParameters.addCustomFieldValue(csUserField.getId(), value_string);
issueInputParameters.setSkipScreenCheck(true);
issueInputParameters.setRetainExistingValuesWhenParameterNotProvided(true, true);
UpdateValidationResult updateValidationResult = issueService.validateUpdate(user, issue.getId(), issueInputParameters);  
if (updateValidationResult.isValid())
{
    IssueResult updateResult = issueService.update(user, updateValidationResult);
    if (!updateResult.isValid())
    {
        log.warn("ISSUE has NOT been updated. Errors: {}\n", updateResult.getErrorCollection().toString());
    }
    else
    {
        log.warn("ISSUE has been updated.\n");
    }
}
else
{
    log.warn("ISSUE has NOT been updated. Errors: {}\n", updateResult.getErrorCollection().toString());
}
