**Maven安装与配置**

**一、准备**

[1. JDK安装与配置][1. JDK]

1.  Eclipse安装（[tomcat配置][tomcat]）
2.  下载Maven程序包

**二、Maven下载与安装**

1.  下载最新版的Maven程序：[https://maven.apache.org/download.cgi][https_maven.apache.org_download.cgi]  
    ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDQzMzQ5OQ_size_16_color_FFFFFF_t_70]
2.  将文件解压到D:\\Program Files\\Apache\\maven目录下:  
    ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDQzMzQ5OQ_size_16_color_FFFFFF_t_70 1]
3.  新建环境变量MAVEN\_HOME，赋值D:\\Program Files\\Apache\\maven  
    ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDQzMzQ5OQ_size_16_color_FFFFFF_t_70 2]
4.  编辑环境变量Path，追加%MAVEN\_HOME%\\bin;  
    ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDQzMzQ5OQ_size_16_color_FFFFFF_t_70 3]
5.  可以通过DOS命令检查一下我们是否安装成功：  
    mvn -v  
    ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDQzMzQ5OQ_size_16_color_FFFFFF_t_70 4]

**三、配置Maven本地仓库**

1.  在D:\\Program Files\\Apache\\目录下新建maven-repository文件夹，该目录用作maven的本地库。
2.  打开D:\\Program Files\\Apache\\maven\\conf\\settings.xml文件，查找下面这行代码：  
    `<localRepository>/path/to/local/repo</localRepository>`  
    localRepository节点默认是被注释掉的，需要把它移到注释之外，然后将localRepository节点的值改为我们创建的目录D:\\Program Files\\Apache\\maven-repository。  
    ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDQzMzQ5OQ_size_16_color_FFFFFF_t_70 5]
3.  localRepository节点用于配置本地仓库，本地仓库其实起到了一个缓存的作用，它的默认地址是 C:\\Users\\用户名.m2。

当我们从maven中获取jar包的时候，maven首先会在本地仓库中查找，如果本地仓库有则返回；如果没有则从远程仓库中获取包，并在本地库中保存。

此外，我们在maven项目中运行mvn install，项目将会自动打包并安装到本地仓库中。

1.  运行一下DOS命令  
    `mvn help:system`
2.  如果前面的配置成功，那么D:\\Program Files\\Apache\\maven-repository会出现一些文件。

**四、配置Eclipse的Maven环境**

1.  打开Window->Preferences->Maven->Installations，右侧点击Add。找到maven的安装目录，然后Finish。  
    ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDQzMzQ5OQ_size_16_color_FFFFFF_t_70 6]  
    选中刚刚添加的maven，并Apply。  
    ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDQzMzQ5OQ_size_16_color_FFFFFF_t_70 7]  
    打开Window->Preferences->Maven->User Settings，配置如下并Apply：  
    ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDQzMzQ5OQ_size_16_color_FFFFFF_t_70 8]  
    配置完 settings.xml 保存后 打开确认路径是否有更改，如图所示Rejndex路径已自动更改  
    ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDQzMzQ5OQ_size_16_color_FFFFFF_t_70 9]

将之前C:\\Users.m2\\repository的Maven所下载的文件全部剪切到现在新的配置D:\\Program Files\\soft\\apache\\maven-respository仓库里，然后重启Eclipse  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDQzMzQ5OQ_size_16_color_FFFFFF_t_70 10]  
至此就完成了对Eclipse里的默认Maven本地仓库的更改  
***仓库地址默认C盘，可按上述操作更改仓库地址。***
