私有Maven仓库安装和使用

安装

这里选择安装的是windows平台，linux安装类似，下载可能要梯子

官网下载页

https://help.sonatype.com/repomanager2/download

下载链接

https://download.sonatype.com/nexus/oss/nexus-latest-bundle.zip

这里下载2.X的最新版本 捆绑包，内置jetty容器，可作为独立服务运行，jdk 要求1.8

（个人觉得 2.x版本更好用）

下载解压后，可以看到两个目录

安装： （这里以本机安装作为示例）

管理员身份进入解压后的bin目录下，执行 nexus 命令可以看到 提示命令

执行 nexus install ,等待安装完成

执行 nexus start 启动 nexus

访问  http://127.0.0.1:8081/nexus ,看到该页面即表示正常启动

基础使用

登录

右上角点击登录 admin/admin123 （初始默认账号密码）

创建 my-maven-release 和 my-maven-snapshot

（名字自定义）,作为稳定版和快照版私有仓库

两个仓库type都是 hosted 类型

my-maven-release

创建 my-maven-snapshot ,把 Repository Policy 改为Snapshot

至此，仓库已经创建完毕

nexus中所有仓库的实际位置都存储在

nexus-2.14.19-01-bundle\sonatype-work\nexus\storage 目录下

部署项目到私有库

打开一个maven项目

在pom.xml添加以下内容

<distributionManagement>

    <repository>

        <id>my-maven-releases</id>

        <url>http://127.0.0.1:8081/nexus/content/repositories/my-maven-releases</url>

    </repository>

    <snapshotRepository>

        <id>my-maven-snapshot</id>

        <url>http://127.0.0.1:8081/nexus/content/repositories/my-maven-snapshot</url>

    </snapshotRepository>

</distributionManagement>

内容来源于刚才创建的仓库

maven的setting.xml中配置 server,因为访问仓库需要账号密码

<server>  

    <id>my-maven-releases</id>  

    <username>admin</username>  

    <password>admin123</password>  

</server>  

<server>  

    <id>my-maven-snapshot</id>  

    <username>admin</username>  

    <password>admin123</password>  

</server>

　　

maven项目下执行 mvn deploy

或者使用IDE 的maven插件执行clean deploy

deploy成功之后可以看到nexus远程仓库有了相关的jar包信息，本地maven仓库 org.example 文件夹下也会出现相关jar包

直接上传jar包到私有maven库

配置完成后，选择文件，点击 Add Artifact , 最后点击上传

更改nexus 仓库平台 账号密码

或者点击 User ,选中右键

Nexus OSS 修改 端口号

打开 conf 文件夹下的 nexus.properties 文件

从私有仓库拉取依赖

配置公共库

将右边配置的仓库移动到左边并保存 ，就可以在公共库下看到之前deploy的项目的相关信息

这边也可以添加aliyun代理仓库并把它移动到公共库下，

这样个人的setting.xml 阿里云 镜像配置都可以省略了

但是如果不是公司网络，就会下不了依赖，个人可去可不去

setting.xml配置

servers部分  （这边如果不需要上传项目到私有仓库，可以不需要配置）

	</servers>
                <server>
			<id>my-maven-releases</id>
			<username>admin</username>
			<password>admin123</password>
		</server>
		<server>
			<id>my-maven-snapshot</id>
			<username>admin</username>
			<password>admin123</password>
		</server>
	</servers>

Mirrors部分 用aliyun的maven仓库，可以不用变

私有仓库配置部分

<profiles>
    <profile>
		<id>my-maven</id>
		<repositories>
			<repository>
				<id>public</id>
				<name>public Repository</name>
				<url>http://127.0.0.1:8081/nexus/content/groups/public/</url>
				<releases>
					<enabled>true</enabled>
				</releases>
				<snapshots>
					<enabled>true</enabled>
				</snapshots>
			</repository>
		</repositories>
		<pluginRepositories>

				<url>http://127.0.0.1:8081/nexus/content/groups/public/</url>
			</pluginRepository>
		</pluginRepositories>
	</profile>

  </profiles>　

记得激活配置

	<activeProfiles>
		<activeProfile>my-maven</activeProfile>
	</activeProfiles>

完整的配置如下：

 | 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.

  <!-- pluginGroups
   | This is a list of additional group identifiers that will be searched when resolving plugins by their prefix, i.e.

  <!-- mirrors
   | This is a list of mirrors to be used in downloading artifacts from remote repositories.
   |
   | It works like this: a POM may declare a repository to use in resolving certain artifacts.
   | However, this repository may have problems with heavy traffic at times, so people have mirrored
   | it to several places.
   |
   | That repository definition will have a unique id, so we can create a mirror reference for that
   | repository, to be used as an alternate download site. The mirror site will be the preferred
   | server for that repository.

  <mirrors>
    <!-- mirror
     | Specifies a repository mirror site to use instead of a given repository. The repository that
     | this mirror serves has an ID that matches the mirrorOf element of this mirror. IDs are used
     | for inheritance and direct lookup purposes, and must be unique across the set of mirrors.

  <!-- profiles
   | This is a list of profiles which can be activated in a variety of ways, and which can modify
   | the build process. Profiles provided in the settings.xml are intended to provide local machine-
   | specific paths and repository locations which allow the build to work in the local environment.
   |
   | For example, if you have an integration testing plugin - like cactus - that needs to know where
   | your Tomcat instance is installed, you can provide a variable here such that the variable is
   | dereferenced during the build process to configure the cactus plugin.
   |
   | As noted above, profiles can be activated in a variety of ways. One way - the activeProfiles
   | section of this document (settings.xml) - will be discussed later. Another way essentially
   | relies on the detection of a system property, either matching a particular value for the property,
   | or merely testing its existence. Profiles can also be activated by JDK version prefix, where a
   | value of '1.4' might activate a profile when the build is executed on a JDK version of '1.4.2_07'.
   | Finally, the list of active profiles can be specified directly from the command line.
   |
   | NOTE: For profiles defined in the settings.xml, you are restricted to specifying only artifact
   |       repositories, plugin repositories, and free-form properties to be used as configuration
   |       variables for plugins in the POM.
   |
   |-->
  <profiles>

    <!-- profile
     | Specifies a set of introductions to the build process, to be activated using one or more of the
     | mechanisms described above. For inheritance purposes, and to activate profiles via <activatedProfiles/>
     | or the command line, profiles have to have an ID that is unique.
     |
     | An encouraged best practice for profile identification is to use a consistent naming convention
     | for profiles, such as 'env-dev', 'env-test', 'env-production', 'user-jdcasey', 'user-brett', etc.
     | This will make it more intuitive to understand what the set of introduced profiles is attempting
     | to accomplish, particularly when you only have a list of profile id's for debug.
     |
     | This profile example uses the JDK version to trigger activation, and provides a JDK-specific repo.
    <profile>
      <id>jdk-1.4</id>

      <activation>
        <jdk>1.4</jdk>
      </activation>

      <repositories>
        <repository>
          <id>jdk14</id>
          <name>Repository for JDK 1.4 builds</name>
          <url>http://www.myhost.com/maven/jdk14</url>
          <layout>default</layout>
          <snapshotPolicy>always</snapshotPolicy>
        </repository>
      </repositories>
    </profile>
    -->

    <!--
     | Here is another profile, activated by the system property 'target-env' with a value of 'dev',
     | which provides a specific path to the Tomcat instance. To use this, your plugin configuration
     | might hypothetically look like:
     |
     | ...
     | <plugin>
     |   <groupId>org.myco.myplugins</groupId>
     |   <artifactId>myplugin</artifactId>
     |
     |   <configuration>
     |     <tomcatLocation>${tomcatPath}</tomcatLocation>
     |   </configuration>
     | </plugin>
     | ...
     |
     | NOTE: If you just wanted to inject this configuration whenever someone set 'target-env' to
     |       anything, you could just leave off the <value/> inside the activation-property.
     |
    <profile>
      <id>env-dev</id>

      <activation>
        <property>
          <name>target-env</name>
          <value>dev</value>
        </property>
