【问题标题】：Getting Project build error: Non-resolvable parent POM error in pom获取项目构建错误：pom 中不可解决的父 POM 错误
【发布时间】：2020-06-13 07:33:31
【问题描述】：

我通过 spring initializr 创建了 spring boot 项目，在导入新的 maven 项目时，eclipse 显示以下错误。注意：我使用的是 eclipse Luna（32 位）和 java 1.8。

Project build error: Non-resolvable parent POM: Failure to transfer org.springframework.boot:spring-boot-starter-parent:pom:2.3.1.RELEASE from http://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced. Original error: Could not transfer artifact org.springframework.boot:spring-boot-starter-parent:pom:2.3.1.RELEASE from/to central (http://repo.maven.apache.org/maven2): Failed to transfer http://repo.maven.apache.org/maven2/org/springframework/boot/spring-boot-starter-parent/2.3.1.RELEASE/spring-boot-starter-parent-2.3.1.RELEASE.pom. Error code 501, HTTPS Required and 'parent.relativePath' points at no local POM.

这是我的 pom.xml 文件代码。

【问题讨论】：

确保您已正确导入项目。如果您已经从 spring 初始化程序创建了项目，请确保在解压缩和导入时导入包含 pom 和 .project 的文件夹，而不是高于此级别。

【解决方案1】：

尝试将以下内容添加到您的 pom 中，然后再次尝试构建添加此子代码后，它对我有用，谢谢

<repositories>

    <repository>
        <id>central</id>
        <name>Central Repository</name>
        <url>https://repo.maven.apache.org/maven2</url>
        <layout>default</layout>
        <snapshots>
            <enabled>false</enabled>
        </snapshots>
    </repository>

</repositories>

【讨论】：

如果这不起作用，请在删除 .m2 目录后尝试构建
