Spring Boot Maven构建失败

Question

我是maven的新手。但是，我正在尝试使用Gitlab CI Runner进行自动化测试和构建/部署。

我从我的同事那里获得了当前的maven配置。

当作业运行时，它会在几秒钟后失败，并显示以下错误消息：

Downloaded: https://repo.maven.apache.org/maven2/org/springframework/security/spring-security-bom/4.2.3.RELEASE/spring-security-bom-4.2.3.RELEASE.pom (5 KB at 101.0 KB/sec)

这是我的春天依赖：

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.5.9.RELEASE</version>
</parent>

<dependencies>
    <dependency>

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-jpa</artifactId>
    </dependency>
</dependencies>

我感谢任何帮助，我找不到我的错误的解决方案：/

非常感谢！

Answer 1

我想你的意思是

<!-- 
https://mvnrepository.com/artifact/org.springframework.boot/spring-boot
-configuration-processor -->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-configuration-processor</artifactId>
</dependency>

不是spring-boot-starter-processor，请在这里查看：https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-configuration-processor/1.5.9.RELEASE

Answer 2

看起来你遇到的根本问题是尝试使用不存在的依赖项（来自spring-boot-starter-processor的org.springframework.boot）。将依赖项名称修复为父级中实际定义的依赖项名称 - spring-boot-starter-parent也将修复您的“版本”问题。

您看到的错误是说不同的事情（没有定义版本），因为每个maven依赖项需要直接定义版本或在依赖项管理中定义。由于您已将spring-boot-starter-parent设置为父级，因此它为所有有效的依赖项使用依赖性版本。

如果由于任何原因这是一个正确的依赖名称（这将是非常奇怪的），您将通过正确定义版本来修复错误，如：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-processor</artifactId>
    <version>(insert version here)</version>
</dependency>
