项目构建错误：不可解析的导入 POM：无法传输 org.springframework.cloud:spring-cloud-dependencies:pom:Greenwich.RC2

Question

我在 Verizon 防火墙限制下工作，当我在 netflix 依赖项下安装时，它显示如下编译时错误是什么问题？，我是否必须添加其他信息，有人可以帮我吗？

Answer 1

Spring 使用版本控制语法RC来指示 Release Candidate。 候选版本需要在 pom.xml 中包含里程碑存储库段：

<repositories>
    <repository> 
        <id>repository.spring.milestone</id> 
        <name>Spring Milestone Repository</name> 
        <url>http://repo.spring.io/milestone</url> 
    </repository>
</repositories>

更多信息在这里和这里。 由于 Spring Greenwich Release 自2019 年 1 月 23 日起可用，您可能需要检查您的依赖项是否在发行版本中可用。

为 spring-cloud 版本添加全局属性。

<properties>
        <java.version>11</java.version>
        <spring-cloud.version>Greenwich.RELEASE</spring-cloud.version>
</properties>

将其注入依赖管理

<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>

然后添加存储库

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