安裝Maven並配置環境變數

配置maven環境變數 安裝maven,配置好本地倉庫
① 將下載下來的maven安裝包直接解壓即可。
②配置maven settings.xml
位置:D:\software\maven\apache-maven-3.3.9\conf 下面

開啟settings.xml 設定檔
需要配置的地方有：
①配置本地倉庫的位置,在紅圈位置配置本地倉庫

② 配置國內鏡像，在紅圈位置配置阿里雲鏡像

③配置jdk預設版本，在紅圈位置配置你的jdk版本
添加新的系統內容變數

3.更新系統PATH 變數， 添加;%MAVEN_HOME%\bin;到尾部

4.測試maven是否配置成功
開啟命令列視窗，輸入mvn -v，如果有maven 版本資訊輸出則證明配置成功，否則請查看自己配置路徑等是否正確。
注意：安裝maven前請確保已安裝JDK並成功配置其環境變數

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. | |--><settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"          xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">  <!-- localRepository   | The path to the local repository maven will use to store artifacts.   |   | Default: ${user.home}/.m2/repository  <localRepository>/path/to/local/repo</localRepository>  -->   <localRepository>D:\software\maven\MavenRepository</localRepository>  <!-- interactiveMode   | This will determine whether maven prompts you when it needs input.

Maven will automatically add the group identifiers   | "org.apache.maven.plugins" and "org.codehaus.mojo" if these are not already contained in the list.   |-->  <pluginGroups>    <!-- pluginGroup     | Specifies a further group identifier to use for plugin lookup.    <pluginGroup>com.your.plugins</pluginGroup>    -->  </pluginGroups>  <!-- 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.   |-->  <proxies>    <!-- proxy     | Specification for one proxy, to be used in connecting to the network.     |    <proxy>      <id>optional</id>      <active>true</active>      <protocol>http</protocol>      <username>proxyuser</username>      <password>proxypass</password>      <host>proxy.host.net</host>      <port>80</port>      <nonProxyHosts>local.net|some.host.com</nonProxyHosts>    </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>    </server>    -->    <!-- Another sample, using keys to authenticate.    <server>      <id>siteServer</id>      <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>     -->     <mirror>            <id>alimaven</id>            <name>aliyun maven</name>            <url>http://maven.aliyun.com/nexus/content/groups/public/</url>            <mirrorOf>central</mirrorOf>        </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>    -->      <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>        </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>
