Jira Server REST API：使用 JRJC 正确设置自定义字段

import com.atlassian.jira.rest.client.api.JiraRestClient;

JiraRestClient jira = /* ... 初始化 JiraRestClient ... */;
String projectKey = "TEST"; // 替换为你的项目键
String summary = "这是我的新 Issue 概要";
String description = "这是一个通过 JRJC 创建的 Issue 描述。";

// 获取 Issue 类型 ID
Long testIssueTypeId = getTestIssueTypeId(projectKey); // 假设此方法能获取到 Issue 类型 ID

// return jira.getIssueClient().createIssue(input).claim();

// 尝试设置自定义字段的代码示例 (可能导致错误)
