背景
直白点：Jenkins的进阶操作，让你可以更随心所欲的定义Jenkins的行为。
开发环境
- Java Development Kit (JDK)：推荐17
-
Maven：>=3.8.3
#maven镜像加速 $ vi ~/maven-3.8.6/conf/settings.xml # 添加阿里云镜像 <mirror> <id>alimaven</id> <name>aliyun?maven</name> <url>http://maven.aliyun.com/nexus/content/groups/public/</url> <mirrorOf>central</mirrorOf> </mirror> - IDE ：
IntelliJ IDEAorEclipse
创建一个插件
mvn -U archetype:generate -Dfilter="io.jenkins.archetypes:"
注意:执行该命令可能会得到以下结果，并不出现提示交互，也不会生成maven项目。
[INFO] Generating project in Interactive mode
[WARNING] No archetype found in remote catalog. Defaulting to internal catalog
[INFO] Your filter doesn't match any archetype, so try again with another value.

这是因为maven在本地仓库根目录archetype-catalog.xml文件中没找到groupId为io.jenkins.archetypes的archetype，之后会在远端仓库的该文件中查找，如果还是没找到则出现上述问题。
解决方法：将archetype-catalog.xml文件下载到本地Maven仓库根目录即可 (注意，这不是指的安装路径，而是mvn运行时默认的存放repository的路径，一般在用户根目录下的一个隐藏目录，~/.m2。)，获取地址:
https://repo1.maven.org/maven2/archetype-catalog.xml
重新执行命令：
10066 ◯ : mvn -U archetype:generate -Dfilter="io.jenkins.archetypes:"
...
Choose archetype:
1: remote -> io.jenkins.archetypes:empty-plugin (Skeleton of a Jenkins plugin with a POM and an empty source tree.)
2: remote -> io.jenkins.archetypes:global-configuration-plugin (Skeleton of a Jenkins plugin with a POM and an example piece of global configuration.)
3: remote -> io.jenkins.archetypes:global-shared-library (Uses the Jenkins Pipeline Unit mock library to test the usage of a Global Shared Library)
4: remote -> io.jenkins.archetypes:hello-world-plugin (Skeleton of a Jenkins plugin with a POM and an example build step.)
5: remote -> io.jenkins.archetypes:scripted-pipeline (Uses the Jenkins Pipeline Unit mock library to test the logic inside a Pipeline script.)
Choose a number or apply filter (format: [groupId:]artifactId, case sensitive contains): : 4
Choose io.jenkins.archetypes:hello-world-plugin version:
1: 1.1
2: 1.2
3: 1.3
4: 1.4
5: 1.5
6: 1.6

生成并运行插件
Maven 的HPI插件用于构建和打包Jenkins插件的。它还提供了一种使用插件运行Jenkins实例的方便方法：
mvn hpi:run
#默认端口是8080,可以使用 -Dport指定端口
mvn hpi:run -Dport=5000
命令执行后，如果显示 Jenkins is fully up and running，浏览器打开http://localhost:5000/jenkins/,查看插件功能。
PS:插件目录下面的work/目录，就是Jenkins的home目录。
- 新建
Freestyle project - 在
Build Steps选择Say hello world，如下：
Console Output
Started by user unknown or anonymous
Running as SYSTEM
Building in workspace /home/zhaofusen/eclipse-workspace/demo-plugin/work/workspace/test_plugin
Hello, Hello 2024!
Finished: SUCCESS
PS:终端执行Ctrl + C,可以停止Jenkins。
