按照https://www.codenong.com/cs106759370/教程进行cicd配置；
发现问题：
1.配置完成后提交测试代码，Jenkins并没有自动触发任何构建job？

我使用的是ngrok进行内网穿透，这个工具对webhook的请求都做了响应，但是都处理成forbidden，无法正常访问到本地localhost:8080,所以未正常触发持续集成操作。
--forbidden为什么会返回403，待查后补充。。。
- 第一次构建提示

解决方法：公司网络慢因此设置git配置参数，否则因此超时退出
$ git config --global http.lowSpeedLimit 0
$ git config --global http.lowSpeedTime 999999
$ git config --global http.postBuffer 5242880
3.第二次构建提示

这个是我Jenkins上的maven_home配置错了，Mac应该是/usr/local/Cellar/maven/3.8.4/libexec，之前少了libexec目录
4.第四次构建问题
Parsing POMs
ERROR: No such file /Users/xxxxxxxxx/.jenkins/workspace/jenkinsCICDtest/Jenkins/pom.xml
Perhaps you need to specify the correct POM file path in the project configuration?
Finished: FAILURE
参考内容
参考配置文档配置的build处为jenkins/pom.xml，而实际上我的pom文件在root目录下面，修改为原来的pom.xml路径即可
5.项目里增加了module，在集成编译过程中失败，提示找不到包

</pre>
原因是我在增加的module里面配置的testng依赖，scope处理的是test，而非compile，maven在编译时找不到testng依赖。
将maven的pom.xml testng修改如下
<dependency>
<groupId>org.testng</groupId>
<artifactId>testng</artifactId>
<version>6.9.9</version>
<scope>compile</scope>
</dependency>
scope的其他参数如下：
compile
默认的scope，表示 dependency 都可以在生命周期中使用。而且，这些dependencies 会传递到依赖的项目中。适用于所有阶段，会随着项目一起发布
provided
跟compile相似，但是表明了dependency 由JDK或者容器提供，例如Servlet AP和一些Java EE APIs。这个scope 只能作用在编译和测试时，同时没有传递性。
runtime
表示dependency不作用在编译时，但会作用在运行和测试时，如JDBC驱动，适用运行和测试阶段。
test
表示dependency作用在测试时，不作用在运行时。 只在测试时使用，用于编译和运行测试代码。不会随项目发布。
system
跟provided 相似，但是在系统中要以外部JAR包的形式提供，maven不会在repository查找它。
