配置远程maven仓库自己的步骤

---恢复内容开始---

1、首先在远程服务器配置jdk、maven环境，这个可以在网上找

2、Nexus 安装与配置。这个见网上博客（https://blog.csdn.net/lewis_007/article/details/53582537，内容搬走了，望博主见谅）

============================================================

这里介绍下 SonaType Nexus 2.x 的安装（Windows 环境）和配置。

安装

下载

进入Nexus 官网下载页面：https://www.sonatype.com/download-oss-sonatype ，找到 Nexus Repository Manager OSS 2.x 字样，点击 nexus-2.14.1-01-bundle.zip 链接下载。

解压

解压 nexus-2.14.1-01-bundle.zip 到任意路径，例如 D:AppsDevAppssnaptype-nexus ，为行文方便，下文用 %NEXUS_HOME% 代指该路径。
Nexus 安装路径

安装

进入 %NEXUS_HOME% exus-2.14.1-01injsw 目录，这里是一系列以操作系统类型命名的文件夹，各文件夹下存放的是对应的 Nexus 脚本（Nexus 是这么设计目录的，但是，当前 Nexus 只提供了 Windows 的脚本）。
Nexus 服务目录

我这里进入 windows-x86-64 文件夹，以管理员身份运行 install-nexus.bat （安装windows服务，让服务自动重启） 和 start-nexus.bat （运行nexus）。

修改端口在这个路径下：C: exus-2.14.5-02-bundle exus-2.14.5-02conf nexus 文件中，默认端口为8081 ，我改为8088端口了。

Windows 服务

访问

进入 http://localhost:8081/nexus 访问 Nexus 。

成功打开上述页面，表示安装完成。接下来还需要配置，不配置，就长这样。

配置 Nexus

下载远程索引

进入名为 Central 的资源库，在其配置页面，将远程下载索引调整为 true 。
下载远程索引

这时，进入任务调度页面，可以看到一个修复资源库索引的任务正在运行。这个任务是由于资源库的配置变更自动触发的，执行一次，执行完会自动删除，作用是将 Maven 中央仓库的索引（目前，大概 2.6 G ，并且还在增加）下载到私服，一般要执行 1-2 小时，具体执行时长依赖实际网络环境。
任务调度

查询

在配置前，我们做了查询，现在我们再次执行查询，看看查询的结果。

配置 Maven

为了在本地项目中使用到 Nexus 私服，需要为本地 Maven 进行相应配置。

（这里有个问题，都是本地局域网，我不需要修改settings.xml文件内容，修改了结果有问题，添加dependency无法导入包，默认内容如下：）

 | 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.home}/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.

   | Default: ${user.home}/.m2/repository
  <localRepository>/path/to/local/repo</localRepository>
  -->

  <!-- interactiveMode
   | This will determine whether maven prompts you when it needs input. If set to false,
   | maven will use a sensible default value, perhaps based on some other setting, for
   | the parameter in question.
   |
   | Default: true

  <!-- pluginGroups
   | This is a list of additional group identifiers that will be searched when resolving plugins by their prefix, i.e.
   | when invoking a command line like "mvn prefix:goal". Maven will automatically add the group identifiers

  <!-- proxies
   | This is a list of proxies which can be used on this machine to connect to the network.
   | Unless otherwise specified (by system property or command-line switch), the first proxy
   | specification in this list marked as active will be used.

    </proxy>
    -->
  </proxies>

  <!-- servers
   | This is a list of authentication profiles, keyed by the server-id used within the system.
   | Authentication profiles can be used whenever maven must make a connection to a remote server.
   |-->
  <servers>
    <!-- server
     | Specifies the authentication information to use when connecting to a particular server, identified by
     | a unique name within the system (referred to by the 'id' attribute below).
     |
     | NOTE: You should either specify username/password OR privateKey/passphrase, since these pairings are
     |       used together.
     |
    <server>
      <id>deploymentRepo</id>
      <username>repouser</username>
      <password>repopwd</password>

      <privateKey>/path/to/private/key</privateKey>
      <passphrase>optional; leave empty if not used.</passphrase>
    </server>
    -->
  </servers>

  <!-- 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.
     |
    <mirror>
      <id>mirrorId</id>
      <mirrorOf>repositoryId</mirrorOf>
      <name>Human Readable Name for this Mirror.</name>
      <url>http://my.repository.com/repo/path</url>
    </mirror>
     -->
  </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>
      </activation>

      <properties>
        <tomcatPath>/path/to/tomcat/instance</tomcatPath>
      </properties>
    </profile>
    -->
  </profiles>

  <!-- activeProfiles
   | List of profiles that are active for all builds.
   |
  <activeProfiles>
    <activeProfile>alwaysActiveProfile</activeProfile>
    <activeProfile>anotherAlwaysActiveProfile</activeProfile>
  </activeProfiles>
  -->
</settings>

在项目的pom.xml文件添加以下代码，端口要保持一致

    <repositories>
        <repository>
            <id>nexus</id>
            <name>Team Nexus Repository</name>
            <url>http://192.168.1.161:8088/nexus/content/groups/public</url>
        </repository>
    </repositories>
    <pluginRepositories>
        <pluginRepository>
            <id>nexus</id>
            <name>Team Nexus Repository</name>
            <url>http://192.168.1.161:8088/nexus/content/groups/public</url>
        </pluginRepository>
    </pluginRepositories>

idea中maven配置

上图中的settings.xml就是上面的settings代码内容

用文本编辑器（不要用记事本 notepad）打开 %M2_HOME%confsettings.xml 文件，其中 %M2_HOME% 表示本地 Maven 安装目录。

在 settings 节点下设置本地仓库：

<localRepository>E:/work/repo/</localRepository>

在 settings - profiles 节点下设置私服地址：

<profile>
  <id>nexus</id>
  <repositories>
    <repository>
      <id>public</id>
      <name>Local Public Repository</name>
      <url>http://localhost:8081/nexus/content/groups/public/</url>
      <releases>
        <enabled>true</enabled>
      </releases>
      <snapshots>
        <enabled>true</enabled>
        <updatePolicy>always</updatePolicy>
      </snapshots>
    </repository>
  </repositories>
  <pluginRepositories>
    <pluginRepository>
      <id>public</id>
      <name>Local Public Repository</name>
      <url>http://localhost:8081/nexus/content/groups/public/</url>
    </pluginRepository>
  </pluginRepositories>
</profile>

在 settings 节点下激活私服地址：

<activeProfiles>
  <activeProfile>nexus</activeProfile>
</activeProfiles>

总结

以上我们做了三件事：
1. 下载 Nexus ，并将其做成 Windows 服务，便于开机自启动；
2. 配置 Nexus ，下载中央仓库的索引，便于查询构建；
3. 配置 Maven ，设置本地仓库和私服地址，这样本地的每一个 Maven 项目都可以连接到私服，免去每个项目都要指定私服地址的烦恼。

这里，只是一个开始，也许你在下载本地仓库的时候 TIME OUT 了，没有关系，我将在下一篇介绍下 Nexus 的高级配置。
