使用 Spring Framework Cloud 时无法传输工件 from/to 中央 Maven 存储库

Question

我正在尝试使用 Spring Framework Cloud 创建一个 Maven 项目。我定义 pom.xml 文件如下

<parent>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-parent</artifactId>
        <version>Brixton.RELEASE</version>
    </parent>

    <properties>
        <!-- Stand-alone RESTFul application for testing only -->
        <start-class>io.pivotal.microservices.services.Main</start-class>
    </properties>

    <dependencies>
        <dependency>
            <!-- Setup Spring Boot -->
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter</artifactId>
        </dependency>

        <dependency>
            <!-- Setup Spring MVC & REST, use Embedded Tomcat -->
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-thymeleaf</artifactId>
        </dependency>

        <dependency>
            <!-- Setup Spring Data common components -->
            <groupId>org.springframework.data</groupId>
            <artifactId>spring-data-commons</artifactId>
        </dependency>

        <dependency>
            <!-- Testing starter -->
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
        </dependency>

        <dependency>
            <!-- Setup Spring Data JPA Repository support -->
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-jpa</artifactId>
        </dependency>

        <dependency>

            <groupId>org.hsqldb</groupId>
            <artifactId>hsqldb</artifactId>
        </dependency>

        <dependency>
            <!-- Spring Cloud starter -->
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter</artifactId>
        </dependency>

        <dependency>
            <!-- Eureka service registration -->
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-eureka-server</artifactId>

    </dependencies>

当尝试构建 Maven 时，所有依赖项都出现错误

当我转到该位置时，我可以清楚地看到该位置存在 Jar 文件。我还需要添加其他内容到我的 pom.xml 吗？

Answer 1

尝试强制刷新您的依赖项。指定 -U 就是

mvn clean install -U

编辑：您可以清除您的本地发布依赖项并在之后恢复正常 mvn clean install：

mvn dependency:purge-local-repository

无法强制拉取发布依赖项，-U 仅适用于快照依赖项

Answer 2

我在 Eclipse IDE 中尝试了相同的 pom.xml 并且令人惊讶的是它在那里工作。

为了让它在 STS 上运行，我添加了以下属性

<properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
        <java.version>1.8</java.version>
        <start-class>io.pivotal.microservices.services.Main</start-class>
        <spring-cloud.version>Brixton.RELEASE</spring-cloud.version>
    </properties>

参考Unable to download/import package org.springframework.cloud.config.server.EnableConfigServer

这对我有用，尽管我仍然对其中的区别感到好奇。

Answer 3

我在我的项目中遇到了同样的错误，这对我有用。

首先，转到您的 pom.xml 并找到您的 spring-parent 版本。然后转到 https://repo.maven.apache.org/maven2/springframework/spring-parent 并检查是否存在相同的 springframework 版本，如果不存在，请将 springframework 版本更改为现有版本。
