项目构建错误：org.springframework.cloud:'spring-cloud-starter-eureka- server:jar缺少'dependencies.dependency.version'

我正在从https://www.dineshonjava.com/microservices-with-spring-
boot/开发代码。当我从更新的春天开机起动亲1.5.4.RELEASE到2.0.4.RELEASE，构建得到了失败。

谁能指导我这是什么问题？

项目构建错误：org.springframework.cloud:’spring-cloud-starter-eureka-
server:jar缺少’dependencies.dependency.version’。

另一个错误：

如我的评论所示，一些入门者已重命名：https : //github.com/spring-
projects/spring-cloud/wiki/Spring-Cloud-Edgware-Release-
Notes

许多入门者未遵循正常的Spring
Cloud命名约定。在Edgware中，使用不建议使用的启动程序将记录一个警告，并在该警告中使用要使用的新启动程序的名称。

因此更改 spring-cloud-starter-eureka-server 为spring-cloud-starter-netflix-eureka-server。

Android dependency has different version.You should manually set the same version via DependencyReso

有时候导入一些module时，会出现以下问题

Android dependency ''com.android.support:support-v4'' has different version for the compile (23.3.0) and runtime (25.4.0) classpath. You should manually set the same version via DependencyResolution

• 1

这是因为module中可能依赖了不同的支持库，版本不一样。

解决办法
在项目根目录的build.gradle中加入以下代码
将details.useVersion后的值替换为统一的版本.

subprojects {
    project.configurations.all {
        resolutionStrategy.eachDependency { details -> if (details.requested.group == ''com.android.support'' && !details.requested.name.contains(''multidex'') ) { //统一版本号 details.useVersion "25.4.0" } } } }

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

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。

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

  <!-- 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>

<profiles>	
    <profile>
     <id>jdk-1.8</id>
     <activation>
        <activeByDefault>true</activeByDefault>

     </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>
