首先,创建项目,创建一个文件夹:mkdir yakov
进入yakov目录,然后创建一个pom.xml:touch pom.xml,这个xml文件的结构会在另外的章节详细说一下。
使用vi编辑pom.xml,写入基本的项目信息,如下图:
单单是这些还是不够的,接下来需要,配置一些私服和集成。
注:上面的version改为3.0
有关的私服和集成服务在上一篇中写过:http://www.cnblogs.com/yakov/archive/2011/11/19/maven2_shi_jian.html
设置maven从nexus私服下载构件
可以设置某个项目从私服下载,设置项目的pom.xml如下:
1

<project> ... <repositories> <repository> <id>nexus</id> <name>nexus</name> <url>http: //202.117.15.193:8010/nexus/content/groups/public/</url> <releases><enabled> true </enabled></releases> <snapshots><enabled> true </enabled></snapshots> </repository> </repositories> <pluginrepositories> <pluginrepository> <id>nexus</id> <name>nexus</name> <url>http: //202.117.15.193:8010/nexus/content/groups/public/</url> <releases><enabled> true </enabled></releases> <snapshots><enabled> true </enabled></snapshots> </pluginrepository> </pluginrepositories> ... </project> |
但是这需要为每个项目配置一下,有可能你仅仅需要为你开发的所有项目都用这同一个私服,那么很好,settings.xml提供了profile来设置:

上面的配置是针对下载构件的,如果所有的下载都从私服上进行,就需要配置镜像了!如下所示:

以上几个任选一种就可以了,我这里使用了最后一种。
部署自己的构件至nexus
直接在要部署的项目的pom.xml中写入如下代码:
还需要在settings.xml中设置用户名和密码,因为nexus的仓库对于匿名用户是readonly的:
至此,有关私服已经设置好了!
在目录src/main/java下编写plugin
在yakov下创建src/main/java目录
写一个yakovmojo的类:

然后运行mvn clean compile,运行结果如下:
编译完成,这里可移执行安装了,事实上,还应该有对应的测试代码,以后再讲。
运行mvn clean install完后就安装成功了。
最后运行mvn clean deploy 完成发布,查看nexus如下:
