# 1.问题 #

通过IDEA使用Maven进行项目Install时，发送了如题的问题：

> **Maven dependencies are failing with a 501 error: user https://repo.maven.....**

--------------------

# 2.分析 #

具体报错是，SpringCloud的依赖无法从远程Maven下载。报错信息中的下载地址如下：

http://repo.maven.apache.org/maven2/org/springframework/cloud/spring-cloud-dependencies/Greenwich.RELEASE/spring-cloud-dependencies-Greenwich.RELEASE.pom

通过浏览器尝试了一下，确实不可下载：

但是，换成![\\large \\textbf\{\{\\color\{DarkRed\} https\}\}][large _textbf_color_DarkRed_ https]就可以正常访问到了。所以，**原因就是Maven远程库访问方式导致的不可用了。。**

通过参考网上的资料，搜集到如下3种解决方式：

**1.Add a repository in your project´s pom.xml file**

<project> 
    	<repositories> 
    		<repository> 
    			<id>central maven repo</id> 
    			<name>central maven repo https</name> 
    			<url>https://repo.maven.apache.org/maven2</url> 
    		</repository> 
    	</repositories> 
    </project>

**2.Add the repository into a profile in the settings.xml file.**

<profile> 
    	<id>my profile</id> 
    	<repositories> 
    		<repository> 
    			<id>central maven repo</id> 
    			<name>central maven repo https</name> 
    			<url>https://repo.maven.apache.org/maven2</url> 
    		</repository> 
    	</repositories> 
    </profile>

**3.Update you maven version to a new one that uses https values as default. The lastest one at this moment 3.6.3 Download here( [https://maven.apache.org/download.cgi][https_maven.apache.org_download.cgi])**

**备注：**此处就是说，升级自己的Maven版本至最新的版本使用即可！

--------------------

# 3.解决 #

**博主采用的是第三种方式！**对于前面两种方式，有兴趣的朋友也可以尝试一下！！！

此处还出了一个小插曲，就是我选择了Maven的最新版本3.6.3后，居然出现了另外的报错！！！！我岛。。。。。还是贴下异常信息吧：

这个异常的主要原因是因为，**Maven版本与IDEA版本不匹配导致！**

博主目前使用的是2018版本的，

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3l5MzM5NDUyNjg5_size_16_color_FFFFFF_t_70][]

而2018版本的IDEA不能使用最新版本的Maven，后来换成 ![\\large \\textup\{\\textbf\{\{\\color\{DarkRed\} apache-maven-3.5.2\}\}\}][large _textup_textbf_color_DarkRed_ apache-maven-3.5.2] 即可！！！至此，问题就解决啦！！！
