Jenkins插件开发笔记

第一次做Jenkins插件开发,遂将笔记公开分享

插件名称: gettingCase

插件功能: 获取RallyDev上的某一个Test Case信息

 

0.配置.m2/settings.xml

请查阅本文最后的参考资料

 

 1.Maven创建Jenkins插件项目

mvn -U org.jenkins-ci.tools:maven-hpi-plugin:create

第一次执行会比较慢,因为需要下载很多Maven插件.

这个创建项目的过程有2步互动:

第一步需要开发者输入Maven项目的groupId

Enter the groupId of your plugin [org.jenkins-ci.plugins]:

com.technicolor.qcs

第二步需要开发者输入Maven项目的artifactId

Enter the artifactId of your plugin (normally without '-plugin' suffix):

gettingCase

 

2.基于Hello World插件项目,修改以实现自己插件功能

2.1POM

修改pom.xml文件,增加REST访问RallyDev的工具包

    4.0.0
    
        org.jenkins-ci.plugins
        plugin
        1.509.3

    Gets Rally Test Cases

 2.2 编写全局配置页面

/home/hanl/j-ci/gettingCase/src/main/resources/com/technicolor/qcs/gettingCase/GetCasesBuilder/global.jelly

 

 

 2.3 编写JOB配置页面

1  app  Hudson应用程序对象
${app.displayName}. //应用的Display名称

2  it   当前UI所属的模型对象
${it.name} 对应于builder的getName()方法

3  h   一个全局的工具类，提供静态工具方法   

 

/home/hanl/j-ci/gettingCase/src/main/resources/com/technicolor/qcs/gettingCase/GetCasesBuilder/config.jelly

 

2.4 编写扩展点方法

 

一次构建过程通常包括：
SCM checkout - check out出源码
Pre-build    - 预编译
Build wrapper  -准备构建的环境，设置环境变量等
Builder runs   - 执行构建，比如调用calling Ant, Make
Recording    - 记录输出，如测试结果
Notification    - 通知成员

package com.technicolor.qcs.gettingCase;

import com.google.gson.JsonObject;
import com.rallydev.rest.RallyRestApi;
import com.rallydev.rest.request.GetRequest;
import com.rallydev.rest.response.GetResponse;
import com.rallydev.rest.response.Response;

import java.io.IOException;
import java.net.URI;
import java.net.URISyntaxException;

/**

 */
public class RallyClient {
    /*https://github.com/RallyTools/RallyRestToolkitForJavahttps://github.com/RallyTools/RallyRestToolkitForJava */
    private final RallyRestApi restApi;

    public RallyClient(String rally_url, String userName, String password, String proxyURL, String proxyUser, String proxyPassword) throws URISyntaxException {
        restApi = new RallyRestApi(new URI(rally_url), userName, password);
        restApi.setProxy(new URI(proxyURL), proxyUser, proxyPassword);
    }

    public void close() throws IOException {
        restApi.close();
    }

    public String getTestCases(String testCaseId) {
        /*https://rally1.rallydev.com/slm/doc/webservice/*/
        StringBuilder result = new StringBuilder();

        String version = restApi.getWsapiVersion();
        result.append("RallyDev Rest Version=").append(version).append("\n");

        final String query = "/testcase/"+testCaseId;
        GetRequest queryRequest = new GetRequest(query);
        GetResponse casesResponse = null;
        try {
            casesResponse = restApi.get(queryRequest);
        } catch (IOException e) {
            e.printStackTrace();
        }
        printWarningsOrErrors(casesResponse, result);
        JsonObject caseJsonObject = casesResponse.getObject();

        result.append("\n").append("Test Case Name: ").append(caseJsonObject.get("Name").getAsString());
        result.append("\n").append("Test Case Type: ").append(caseJsonObject.get("Type").getAsString());
        result.append("\n").append("Test Case URL: ").append(caseJsonObject.get("_ref").getAsString());

        result.append("\n").append("Test Case's Workspace: ").append( caseJsonObject.get("Workspace").getAsJsonObject().get("_refObjectName")    .getAsString());

        return result.toString();
    }

    private void printWarningsOrErrors(Response response, StringBuilder result) {
        if (response.wasSuccessful()) {
            result.append("\nSuccess.");
            String[] warningList;
            warningList = response.getWarnings();
            for (int i = 0; i < warningList.length; i++) {
                result.append("\twarning:\n" + warningList[i]);
            }
        } else {
            String[] errorList;
            errorList = response.getErrors();
            if (errorList.length > 0) {
                result.append("\nError.");

            }
            for (int i = 0; i < errorList.length; i++) {
                result.append("\terror:\n" + errorList[i]);
            }
        }
    }
}

 3.调试Plugin程序

在终端/控制台,首先执行Maven变量配置命令

set MAVEN_OPTS=-Xdebug -Xrunjdwp:transport=dt_socket,server=y,address=8000,suspend=n

cd到插件项目目录,执行如下命令

hanl@hanl-ubuntu1204:~/j-ci/gettingCase$ mvn clean
hanl@hanl-ubuntu1204:~/j-ci/gettingCase$ mvnDebug hpi:run

 Maven将对8000端口执行监听,以便在IDE中进行断点调试

Preparing to Execute Maven in Debug Mode
Listening for transport dt_socket at address: 8000

 

进入IDE(本例使用IntelliJ),选择Run菜单的Debug,添加一个8000端口的远程服务器

 

添加断点,点击左下角运行调试按钮

此时,终端将执行Maven构建,并启动Jetty服务器.

4.测试

在浏览器中录入Jenkins地址,创建Job并按照上述的配置环节,完成配置.

执行Build Job

此时,断点应其作用,可以在IDE中进行调试和监控.

当完成调试后,进入Jenkins构建结果页面,观察构建结果是否符合预期.

 

到此,获取并显示RallyDev中Test Case的Jenkins插件开发完毕.
