maven集成nexus伺服服务实现项目快速自动化构建与发布

Posted 2022-11-25 北溟溟

前言

在前面的博客centos7案例实战——Nexus3伺服仓库服务器搭建中已经详细讲解了如何在本地搭建自己的maven伺服仓库nexus，本节内容是关于如何在本地使用maven集成nexus伺服服务从而实现项目快速自动化构建与发布。

正文

• 修改本地maven配置文件settings.xml，加入nexus配置

 | This is the configuration file for Maven. It can be specified at two levels:
 |
 |  1. User Level. This settings.xml file provides configuration for a single user,
 |                 and is normally provided in $user.home/.m2/settings.xml.
 |
 |                 NOTE: This location can be overridden with the CLI option:
 |
 |                 -s /path/to/user/settings.xml
 |
 |  2. Global Level. This settings.xml file provides configuration for all Maven
 |                 users on a machine (assuming they're all using the same Maven
 |                 installation). It's normally provided in
 |                 $maven.conf/settings.xml.
 |
 |                 NOTE: This location can be overridden with the CLI option:
 |
 |                 -gs /path/to/global/settings.xml
 |
 | The sections in this sample file are intended to give you a running start at
 | getting the most out of your Maven installation. Where appropriate, the default
 | values (values used when the setting is not specified) are provided.

• idea集成maven配置，使用配置伺服环境的maven

• 本地maven项目直接使用伺服仓库地址获取项目依赖包，增加此处配置会优先使用此处配置获取项目依赖包 

<repositories>
        <repository>
            <id>public</id>
            <name>public</name>
            <url>http://192.168.110.42:8081/repository/maven-public/</url>
            <snapshots>
                <enabled>true</enabled>
            </snapshots>
            <releases>
                <enabled>true</enabled>
            </releases>
        </repository>
</repositories>

• 本地项目配置伺服地址，实现本地项目发布到伺服仓库，供第三方使用

ps:此处配置的伺服仓库id要与maven配置中settings.xml的serverid一致，保证能通伺服仓库的授权验证

<!--伺服发布地址-->
<distributionManagement>
        <repository>
            <id>releases</id>
            <name>releases</name>
            <url>http://192.168.110.42:8081/repository/maven-releases/</url>
        </repository>

        <snapshotRepository>
            <id>snapshots</id>
            <name>snapshots</name>
            <url>http://192.168.110.42:8081/repository/maven-snapshots/</url>
        </snapshotRepository>
</distributionManagement>

• 使用idea发布本地maven项目到nexus伺服仓库

•  查看伺服仓库是否有本地打包发布后的项目工程文件

PS： pom版本号包含SNAPSHOT，例如0.0.1-SNAPSHOT，会将包打包到snapshots仓库，并且每次都会生成一个新的包，如果版本号不包含SNAPSHOT，则会打包到releases仓库，只会有一个包。​​​​​​​​​​​​​​
