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:\Tools\jenkins-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:\Tools\jenkins-plugin>mvn archetype:generate -Dfilter=io.jenkins.archetypes

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。
