// HttpClient的get方法 待验证，用于检测前一次build的状态 已ok
	public static String doGet(String jobName) throws ClientProtocolException, IOException {
		// jenkins登录账号
		String username = "###";
		// jenkins登录密码
		String password = "###";
		// 登录url http://your_jenkins:8080/job/your_job/lastBuild/api/xml
		String jenkinsUrl = "http://172.16.0.18:18080/jenkins";

		// jenkins构建job的url
		String jenkinsBuildUrl = jenkinsUrl + "/job/" + jobName + "/lastBuild/api/xml";

		URI uri = URI.create(jenkinsBuildUrl);
		HttpHost host = new HttpHost(uri.getHost(), uri.getPort(), uri.getScheme());
		CredentialsProvider credsProvider = new BasicCredentialsProvider();
		credsProvider.setCredentials(new AuthScope(uri.getHost(), uri.getPort()),
				new UsernamePasswordCredentials(username, password));
		// Create AuthCache instance
		AuthCache authCache = new BasicAuthCache();
		// Generate BASIC scheme object and add it to the local auth cache
		BasicScheme basicAuth = new BasicScheme();
		authCache.put(host, basicAuth);
		CloseableHttpClient httpClient = HttpClients.custom().setDefaultCredentialsProvider(credsProvider).build();
		// HttpPost httpPost = new HttpPost(uri);
		HttpGet request = new HttpGet(uri); // 发送get请求
		HttpClientContext localContext = HttpClientContext.create();
		localContext.setAuthCache(authCache);
		HttpResponse response = httpClient.execute(host, request, localContext);
		String result = EntityUtils.toString(response.getEntity());

		System.out.println(result);
		return result;
