xml - Spring boot POM.xml 缺少依赖项

问题描述

我刚刚制作了一个新的 spring starter 项目，但我不断收到此错误：

项目构建错误：org.springframework.boot:spring-boot-starter:pom 的“dependencies.dependency.version”缺失

我的完整 POM.xml 如下：

 <?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        <version>1.5.19.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

解决方案

更正的 pom 应该如下所示。通过指定在你的 pom 中有几个问题<type>pom</type>。
