导入SpringCloud依赖失败如何解决

这篇“导入SpringCloud依赖失败如何解决”文章的知识点大部分人都不太理解，所以小编给大家总结了以下内容，内容详细，步骤清晰，具有一定的借鉴价值，希望大家阅读完这篇文章能有所收获，下面我们一起来看看这篇“导入SpringCloud依赖失败如何解决”文章吧。

导入SpringCloud依赖踩坑

在使用SpringCloud的时候需要导入spring-cloud-dependencies的依赖,

在springcloud的官网上面可以查到版本Version 但是在上面复制下来的版本号如下：

<dependencyManagement>   <dependencies>      <dependency>         <groupId>org.springframework.cloud</groupId>         <artifactId>spring-cloud-dependencies</artifactId>         <version>Dalston SR3</version>         <type>pom</type>         <scope>import</scope>      </dependency>   </dependencies></dependencyManagement>

不知道什么原因，在公司的电脑能可以正常的将依赖下载到本地库，但是回到宿舍用自己的电脑发现总是下载不下来，一直都是lastUpdate 

上网找解决方案 

最后找到maven-repository中发现版本号如下：

<dependencyManagement>   <dependencies>      <dependency>         <groupId>org.springframework.cloud</groupId>         <artifactId>spring-cloud-dependencies</artifactId>         <version>Dalston.SR3</version>         <type>pom</type>         <scope>import</scope>      </dependency>   </dependencies></dependencyManagement>

相对比可以发现, maven-repository中的版本号比springcloud官网中的版本号多了一个点(.),采用maven-repository中的版本号则可以将依赖下载到版本库

springCloud依赖导入失败

刚开始用spring Initializr创建spring boot项目，添加spring cloud依赖不成功

原因是：需要手动添加版本号
