如何在Java中从Jenkins获取作业的最后构建日期

import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;
import com.fasterxml.jackson.databind.JsonNode;
import com.fasterxml.jackson.databind.ObjectMapper;

public class JenkinsLastBuildDate {
    public static void main(String[] args) {
        String jenkinsUrl = "http://jenkins服务器地址";
        String jobName = "作业名称";

        // 构建API的URL
        String apiUrl = jenkinsUrl + "/job/" + jobName + "/api/json";

        try {
            // 创建HttpClient实例
            HttpClient httpClient = HttpClientBuilder.create().build();

            // 创建HttpGet请求
            HttpGet httpGet = new HttpGet(apiUrl);

            // 发送请求并获取响应
            HttpResponse response = httpClient.execute(httpGet);

            // 读取响应内容
            String jsonResponse = EntityUtils.toString(response.getEntity());

            // 解析JSON响应
            ObjectMapper objectMapper = new ObjectMapper();
            JsonNode jsonNode = objectMapper.readTree(jsonResponse);

            // 获取最后构建日期字段
            String lastBuildDate = jsonNode.get("lastBuild").get("timestamp").asText();

            // 处理最后构建日期，例如转换为Java的日期对象
            // ...

            System.out.println("最后构建日期：" + lastBuildDate);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
