配置Maven镜像仓库，国内Maven镜像仓库，Maven中央仓库，国内Maven仓库大全的配置笔记记录_maven repository hosts

前言

在以前博主每次遇到环境变更时，博主就要大费周折的去整理以下Maven项目的 settings.xml 配置文件，什么镜像地址啦，仓库地址啦等等，很是浪费时间，在这儿记录哈，以便下次直接复制粘贴即可，为什么非要花时间整理能，在以前博主还是一个新手的时候， settings.xml 中配置的镜像地址总是只有一个，现在博主的配置文件里是，能有多少个就有多少个，比如在某天的社区里，看到一个新的即稳定，又快速的地址，我会立刻的毫不犹豫的加入进去（当然这只是博主个人的经验总结和建议）。

Maven镜像仓库地址配置

1、到一个新的项目中环境中，首先需要配置Maven的本地地址（这儿主要说Maven）在 settings.xml 配置文件中找到 localRepository 节点，内容如下：

<localRepository>D:\Install_Applications\apache-maven-3.5.3\.m2\repository</localRepository>

2、配置 Maven 镜像地址，在 settings.xml 配置文件中找到 mirrors 配置节点，示例内容如下：

<mirrors>
	-->
	<!-- 阿里云Maven镜像仓库 该仓库目前存在于北京市大兴区 -->
	<mirror>
		<id>alimaven</id>
		<name>aliyun maven</name>
		<url>http://maven.aliyun.com/nexus/content/groups/public/</url>
		<mirrorOf>central</mirrorOf>
	</mirror>
</mirrors>

3、配置 Maven 中央仓库地址，在 settings.xml 配置文件中找到 配置节点，示例内容如下：

<profile>
	<id>jdk‐1.8</id>
	<activation>
		<activeByDefault>true</activeByDefault>	
		<jdk>1.8</jdk>
	</activation>
	<properties>
		<maven.compiler.source>1.8</maven.compiler.source>
		<maven.compiler.target>1.8</maven.compiler.target>
		<maven.compiler.compilerVersion>1.8</maven.compiler.compilerVersion>
	</properties>
	<!-- dubbo 官方的解决方案 -->
	<repositories>
		<repository>
			<id>sonatype-nexus-snapshots</id>
			<url>https://oss.sonatype.org/content/repositories/snapshots</url>
			<releases>
				<enabled>false</enabled>
			</releases>
			<snapshots>
				<enabled>true</enabled>
			</snapshots>
		</repository>
	</repositories>
</profile>

4、settings.xml 配置文件示例内容如下（注：是基于apache-maven-3.5.3 版本的）：

 | 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.

  <!-- 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

  <!-- 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>

    <!--
     | 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>
