记录瞬间
最近想要了解一下Jenkins的插件如何开发，所以在网上找了一些资料，但是经过一番周折，发现之前的一些方法不能使用了，在此呢，根据自己的一些经历，简述一些开发Jenkins插件变化的地方。
网上主要集中在构建Jenkins插件的框架上，前后的一些信息基本不变，比如：对Maven、Java版本的要求，修改settings.xml文件，后续开发代码的编写等基本都是不变的。
JDK版本要求在1.6以上、Maven官方要求版本在3以上
settings.xml文件需要配置如下：
<settings>
<pluginGroups>
<pluginGroup>org.jenkins-ci.tools</pluginGroup>
</pluginGroups>
<profiles>
<!-- Give access to Jenkins plugins -->
<profile>
<id>jenkins</id>
<activation>
<activeByDefault>true</activeByDefault> <!-- change this to false, if you don't like to have it on per default -->
</activation>
<repositories>
<repository>
<id>repo.jenkins-ci.org</id>
<url>https://repo.jenkins-ci.org/public/</url>
</repository>
</repositories>
<pluginRepositories>
<pluginRepository>
<id>repo.jenkins-ci.org</id>
<url>https://repo.jenkins-ci.org/public/</url>
</pluginRepository>
</pluginRepositories>
</profile>
</profiles>
<mirrors>
<mirror>
<id>repo.jenkins-ci.org</id>
<url>https://repo.jenkins-ci.org/public/</url>
<mirrorOf>m.g.o-public</mirrorOf>
</mirror>
</mirrors>
</settings>
修改的部分为执行Maven构建命令
原来执行命令为：mvn hpi:create或者mvn -U org.jenkins-ci.tools:maven-hpi-plugin:create 但是实际执行会报错
D:Toolsjenkins-plugin>mvn -U org.jenkins-ci.tools:maven-hpi-plugin:create

根据报错信息中的提示，需要执行的命令已经改为：mvn archetype:generate -Dfilter=io.jenkins.archetypes
我们执行此条命令后，发现并没有实际的变化，只是下载了一些依赖包
D:Toolsjenkins-plugin>mvn archetype:generate -Dfilter=io.jenkins.archetypes [INFO] Scanning for projects...

说明我们的操作只对了一部分，不是完全正确需要进一步的执行，
实际需要执行的命令为：mvn archetype:generate -Dfilter=io.jenkins.archetypes:plugin

上面的配置中，由于groupID和package都没有进行设置，所以，在执行到 Y:: 时，我们可以输入N来进行重新选择

据此，可以在目录下查看到构建新的Jenkins插件的架构。
接下来，就可以顺利的进行代码开发了。开发过程，网上较多，在此不做赘述。
