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

Question

我正在开发 https://www.dineshonjava.com/microservices-with-spring-boot/的代码。当我将 spring-boot-starter-parent 从1.5.4.RELEASE更新为2.0.4.RELEASE时，构建失败了。

谁能指导我是什么问题？

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

另一个错误：

Multiple annotations found at this line:
- For artifact {org.springframework.cloud:spring-cloud-starter-eureka-server:null:jar}: The version cannot be empty. (org.apache.maven.plugins:maven-resources-plugin:3.0.2:resources:default-resources:process-

Answer 1

正如我的评论所示，一些启动器被重命名：https://github.com/spring-projects/spring-cloud/wiki/Spring-Cloud-Edgware-Release-Notes

许多启动器没有遵循正常的Spring Cloud命名约定。在 Edgware 中，使用已弃用的启动器将记录一条警告，其中包含要在其位置使用的新启动器的名称。

所以改变：spring-cloud-starter-eureka-server到spring-cloud-starter-netflix-eureka-server.

Add the following in to your pom.xml  
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
<java.version>1.8</java.version>

</properties>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
</dependency>
OR

<artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
</dependency>
<dependencyManagement>

<dependency>

Answer 3

1º) 从 pom 中删除依赖项.xml 并保存文件;

2º)转到 STS 项目>右键单击> Spring> 编辑初学者>搜索到Eureka Discovery Client并将复选标记>确定"。

这个动作解决了我的问题。

Answer 4

在 Pom 中添加以下 int.xml

<properties>
<java.version>1.8</java.version>
<spring-cloud.version>Greenwich.RELEASE</spring-cloud.version>
</properties>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-webflux</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>

<version>${spring-cloud.version}</version>
<type>pom</type>

</dependency>
</dependencies>

Answer 6

当我为hystrix添加依赖项时，我甚至遇到了类似的错误。

错误

：项目生成错误："依赖项.依赖项.版本" org.springframework.cloud：spring-cloud-starter-hystrix：jar is missing

它在更改 netflix<artifactId>后起作用

from: spring-cloud-starter-hystrix 
to:   spring-cloud-starter-netflix-hystrix

Answer 7

这里有几件事。 我试图创建尤里卡服务器，我遇到了几个问题。

第一件事

如果您使用的是spring-cloud-starter-eureka-server则将其更改为spring-cloud-starter-netflix-eureka-server.

该链接将提供更改的详细信息。 https://github.com/spring-projects/spring-cloud/wiki/Spring-Cloud-Edgware-Release-Notes

我最近从 https://start.spring.io/创建了入门项目，它在pom中具有最新的更改.xml

这就是它的样子

<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
</dependency>

您需要确保 eureka 服务器依赖项版本正确。 您可以通过在属性标记中添加<spring-cloud.version>Greenwich.RELEASE</spring-cloud.version>并在依赖项管理的版本标记中添加${spring-cloud.version}来确保

如果您没有看到<dependencyManagement>标签，请在您的pom中添加整个依赖项.xml

<properties>
<java.version>1.8</java.version>
<spring-cloud.version>Greenwich.RELEASE</spring-cloud.version>
</properties>
	<dependencyManagement>
		<dependencies>
			<dependency>
				<groupId>org.springframework.cloud</groupId>
				<artifactId>spring-cloud-dependencies</artifactId>
				<version>${spring-cloud.version}</version>
				<type>pom</type>
				<scope>import</scope>
			</dependency>
		</dependencies>
	</dependencyManagement>

我希望它有所帮助。

Answer 8

设置版本后：

<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
<version>3.0.0</version>
</dependency>

错误消失了。可能不是生产的最佳解决方案。

Answer 9

尝试添加以下全局版本，

<properties>
<java.version>11</java.version>
<spring-cloud.version>2020.0.2</spring-cloud.version>
</properties>

然后没有版本标签的依赖作为下面，

<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
</dependency>

这可能会对某些人有所帮助。

Answer 10

对于所有在尝试上述故障排除后仍然遇到错误的人，他们可以在pom.xml中添加此依赖项管理，它应该可以工作。

<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-dependencies</artifactId>
<version>${spring-cloud.version}</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>

Answer 11

我尝试了上面发布的所有答案，但没有一个有效。唯一对我有用的方法是在 https://start.spring.io/创建一个演示项目并选择依赖项 尤里卡发现客户端 SPRING，然后查看演示项目的 pom.xml 并与您当前的 POM 进行比较。

下面发布了从 start.spring.io 生成的演示pom.xml我已经添加了注释以列出我在XML中缺少的代码，并且在包括后我能够成功编译它。

请在您当前的 XML 中包含差异。

Answer 12

我通过尝试两件事找到了解决方案，并且都解决了问题，我想这是 netflix-eureka 服务器版本的问题。

方法 1： 只需使用 JDK 11。

方法 2： 如果您使用的是 JDK 8。 然后将此版本标记与版本 3.0.0 一起添加，

<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
<version>3.0.0</version>
</dependency>

虽然这不是最佳做法 并会给出警告

Overriding managed version 3.1.1 for spring-cloud-starter-netflix-eureka-server

但是，它将删除错误。

Answer 13

在依赖项节点为我工作之后将其添加到pom.xml之后。

<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-dependencies</artifactId>
<version>${spring-cloud.version}</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>

Answer 14

这对我有用： 我将初学者父版本从 3.0.0 更改为 2.7.3，将云版本更改为 2021.0.3

<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.7.3</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
<properties>
<java.version>17</java.version>
<spring-cloud.version>2021.0.3</spring-cloud.version>
</properties>

添加 spring-cloud-依赖项和 netflix 存储库后解决 完整的POM.xml如下所示

Answer 16

如果没有任何效果，则问题出在您的 maven 设置中。 检查 Maven 设置：验证 IntelliJ IDEA 是否使用了正确的 Maven 安装和设置。转到"文件"->"设置"->"构建、执行、部署"->"构建工具"->"Maven"。确保"Maven 主目录"指向系统上安装 Maven 的正确位置。更改为捆绑 (Maven 3)。然后问题就会消失

Answer 17

我得到了同样的错误。我的绒球像风箱

</build>

所以我必须像这样改变我的绒球。

<properties>
<java.version>17</java.version>
<!-- Add spring cloud verion --> 
<spring-cloud.version>2022.0.3</spring-cloud.version>
</properties>
<dependencies>
</dependencies>
<!-- Add dependencyManagement --> 
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-dependencies</artifactId>
<version>${spring-cloud.version}</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>

依赖管理只是一个声明，它并没有真正添加依赖关系。
