### 问题描述： ###

之前的maven仓库是在做“淘淘商城”时，跟着老师的步骤做的。现在在学习SpringBoot，创建第一个SpringBoot的maven工程时，pom文件的<parent>报错如下：

Description    Resource    Path    Location    Type  
Project build error: Non-resolvable parent POM for com.bjsxt:01-spring-boot-hello:0.0.1-SNAPSHOT:   
Failure to transfer org.springframework.boot:spring-boot-starter-parent:pom:1.5.10.RELEASE from https://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced.   
Original error: Could not transfer artifact org.springframework.boot:spring-boot-starter-parent:pom:1.5.10.RELEASE from/to central (https://repo.maven.apache.org/maven2): Received fatal alert: protocol\_version and 'parent.relativePath' points at wrong local POM    pom.xml    /01-spring-boot-hello    line 3    Maven pom Loading Problem

### 解决方法：参照这篇文章[https://blog.csdn.net/cherry\_vicent/article/details/107508781][https_blog.csdn.net_cherry_vicent_article_details_107508781] ###

第一步：将安装路径下的apache-maven-3.5.3\\conf\\settings.xml文件复制一份到新地址的.m2目录下面（与repository在同一目录）。![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2NoZXJyeV92aWNlbnQ_size_16_color_FFFFFF_t_70][]

第二步：打开settings.xml做一处修改：此处为修改为从阿里云服务器上下载依赖，强烈建议更换，下载速度会快很多，在文件第160行

原始文件：

<table> 
 <tbody> 
 <tr> 
 <td>&lt;mirrors&gt; &lt;!-- 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. | &lt;mirror&gt; &lt;id&gt;mirrorId&lt;/id&gt; &lt;mirrorOf&gt;repositoryId&lt;/mirrorOf&gt; &lt;name&gt;Human Readable Name for this Mirror.&lt;/name&gt; &lt;url&gt;http://my.repository.com/repo/path&lt;/url&gt; &lt;/mirror&gt; --&gt; &lt;/mirrors&gt;</td> 
 </tr> 
 </tbody> 
</table>

修改后的文件：

<table> 
 <tbody> 
 <tr> 
 <td> &lt;mirrors&gt; &lt;!-- 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. | &lt;mirror&gt; &lt;id&gt;mirrorId&lt;/id&gt; &lt;mirrorOf&gt;repositoryId&lt;/mirrorOf&gt; &lt;name&gt;Human Readable Name for this Mirror.&lt;/name&gt; &lt;url&gt;http://my.repository.com/repo/path&lt;/url&gt; &lt;/mirror&gt; --&gt; &lt;!-- 阿里云镜像 下载配置 --&gt; &lt;mirror&gt; &lt;id&gt;nexus-aliyun&lt;/id&gt; &lt;mirrorOf&gt;*&lt;/mirrorOf&gt; &lt;name&gt;Nexus aliyun&lt;/name&gt; &lt;url&gt;http://maven.aliyun.com/nexus/content/groups/public&lt;/url&gt; &lt;/mirror&gt; &lt;!-- 另一个备用模板 --&gt; &lt;!--&nbsp;&lt;mirror&gt; &lt;id&gt;alimaven&lt;/id&gt; &lt;mirrorOf&gt;central&lt;/mirrorOf&gt; &lt;name&gt;aliyun maven&lt;/name&gt; &lt;url&gt;http://maven.aliyun.com/nexus/content/groups/public/&lt;/url&gt; &lt;/mirror&gt;--&gt; &lt;/mirrors&gt; </td> 
 </tr> 
 </tbody> 
</table>

第三步：完成后重启eclipse。
