Cannot resolve org.springframework.cloud:spring-cloud-starter-netflix-eureka-server:unknown

前言：启动eureka项目，发现右侧maven中的项目dependencies报红，reimport也没用，经排查springcloud和springboot版本号没问题。Spring Cloud

 启动类也是报错，@EnableEurakaServer注入失败

一、本地 maven 配置、仓库下载

    <!--配置本地仓储路径-->
	<localRepository>D:\maven\repository</localRepository>	
 
    <mirror>
		<id>aliyun</id>
		<name>aliyun Maven</name>
		<mirrorOf>*</mirrorOf>
		<url>http://maven.aliyun.com/nexus/content/groups/public/</url>
	</mirror>

 

ps:将仓库已有的删除，重新reimport，还是有问题。

二、解决办法，在pom中指定版本号，版本号要和springboot版本号一致。

<parent>
	<groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-starter-parent</artifactId>
	<version>2.1.1.RELEASE</version>
	<relativePath/> <!-- lookup parent from repository -->
</parent>
 
<properties>
     <java.version>1.8</java.version>
     <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
     <spring-cloud.version>Greenwich.RC1</spring-cloud.version>
</properties>
 
<dependencies>
	<dependency>
		<groupId>org.springframework.cloud</groupId>
		<artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
		<version>2.1.1.RELEASE</version>
	</dependency>
</dependencies>

最后，重新reimport，右侧 maven 中的项目dependencies报红没了，版本号是刚写的 2.1.1.RELEASE

启动类上的 @EnableEurakaServer 也注入成功，登陆 Euraka 启动成功。

三、idea配置自带的Maven

看了之前同事帮忙的截图，pom中是没有指定版本号的，但右侧的maven的版本号 2.1.0.RC2

同事提了一下这个，里面是https

<repositories>
	<repository>
		<id>spring-milestones</id>
		<name>Spring Milestones</name>
		<url>https://repo.spring.io/milestone</url>
	</repository>
</repositories>

同事还帮忙指出了两个解决办法，一是将jdk版本提高到1.8.0.33以上，第二个使用默认的maven

找到idea的安装路径 D:\Program Files\JetBrains\IntelliJ IDEA 2020.1\plugins\maven\lib\maven3\conf

 

配置maven本地仓库，注意看标签位置

  <!-- localRepository
   | The path to the local repository maven will use to store artifacts.
   |
   | Default: ${user.home}/.m2/repository
  <localRepository>/path/to/local/repo</localRepository>
  -->
<!--配置本地仓储路径-->
	<localRepository>D:\maven\repository</localRepository>

配置阿里云加快下载速度，注意看标签位置

<mirrors>
    <!-- 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.
     |
    <mirror>
      <id>mirrorId</id>
      <mirrorOf>repositoryId</mirrorOf>
      <name>Human Readable Name for this Mirror.</name>
      <url>http://my.repository.com/repo/path</url>
    </mirror>
     -->
 
		<mirror>
			<id>aliyun</id>
			<name>aliyun Maven</name>
			<mirrorOf>*</mirrorOf>
			<url>http://maven.aliyun.com/nexus/content/groups/public/</url>
			<mirrorOf>central</mirrorOf>
		</mirror>
		
  </mirrors>

<profiles>	
    <profile>
     <id>jdk-1.8</id>
     <activation>
        <activeByDefault>true</activeByDefault>
        <jdk>1.8</jdk>
     </activation>
     <properties>
        <maven.compiler.source>1.8</maven.compiler.source>
        <maven.compiler.target>1.8</maven.compiler.target>
        <maven.compiler.compilerVersion>1.8</maven.compiler.compilerVersion>
     </properties>
    </profile>
  </profiles>

再将maven仓库已有的删除，重新reimport，会发现Maven仓库多了一个包 2.1.0.RC2

 到此问题就全部解决了。
