本文的前提条件：
  • windows7-64bit
  • jdk1.8.0
  • Maven-3.5.0

1- 更新Eclipse中Maven配置

1.1- 修改Eclipse根目录下eclipse.ini文件

D:\DownLoadFiles\eclipse-java-oxygen-R-win32-x86_64\eclipse\eclipse.ini
在“-vm”选项下填写“C:\Program Files\Java\jdk1.8.0_101\bin\javaw.exe”
-startup

plugins/org.eclipse.equinox.launcher_1.4.0.v20161219-1356.jar

--launcher.library

plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.500.v20170531-1133

-product

org.eclipse.epp.package.java.product

-showsplash

org.eclipse.epp.package.common

--launcher.defaultAction

openFile

-vm

C:\Program Files\Java\jdk1.8.0_101\bin\javaw.exe

--launcher.defaultAction

openFile

--launcher.appendVmargs

-vmargs

-Dosgi.requiredJavaVersion=1.8

-Dosgi.instance.area.default=@user.home/eclipse-workspace

-XX:+UseG1GC

-XX:+UseStringDeduplication

-Dosgi.requiredJavaVersion=1.8

-Xms256m

-Xmx1024m

1.2- 修改Eclipse的默认JRE

Windows---》Preferences---》Java ---》Installed JREs ---》Add---》Standard VM，Next---》Directory，选中JDK目录，例如C:\Program Files\Java\jdk1.8.0_101目录，点击Finish

---> 默认勾选"Use default Workspace location"，点击Next

Maven - 在Eclipse中创建Maven项目

--->选择maven-archetype-quickstart，点击Next

Maven - 在Eclipse中创建Maven项目

---> 设置必要的项目参数, 然后点击Finish创建Maven工程
  • Group Id : 项目组织的唯一标识符，实际对应JAVA的包结构，一般都是组织域名的反写形式
  • Artifact Id : 项目的唯一标识符，实际对应项目的名称，就是项目根目录的名称
  • Version : 项目的版本
  • Pacaking : 项目的打包方式，默认为jar

3- 编写pom.xml文件

根据实际需求编写pom.xml文件。

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

  <modelVersion>4.0.0</modelVersion>

  <groupId>testMaven.demo</groupId>

  <artifactId>demo</artifactId>

  <version>0.0.1-SNAPSHOT</version>

  <packaging>jar</packaging>

  <name>demo</name>

  <url>http://maven.apache.org</url>

  <properties>

    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

  </properties>

  <dependencies>

    <dependency>

      <groupId>junit</groupId>

      <artifactId>junit</artifactId>

      <version>4.10</version>

      <scope>test</scope>

    </dependency>

  </dependencies>

</project>

4- 编译与安装

注意：需要引入的依赖jar包必须在仓库存在，否则会提示报错。

4.1- 编译

选中pom.xml文件，鼠标右键Run AS--->Maven build---》在弹出的界面，填写Goals内容：compile，然后Run
如果需要再次运行，可以在填写Goals内容：clean compile，然后Run

4.3- 查看本地仓库

本地仓库包含下载的所有依赖包，默认位于用户目录（例如windows系统：C:\Users\<username>\.m2\repository），可通过setting.xml文件设置。
示例：D:\DownLoadFiles\apache-maven-repo
<localRepository>D:\DownLoadFiles\apache-maven-repo</localRepository>

也可在Eclipse界面Windows---》Preferences---》Maven---》User Settings---》Local Repository，可以查看到本地仓库的位置信息。
