尝试运行我的应用程序时,我在 pom.xml 中遇到以下异常。我看到了一些关于该错误的帖子并关注了它们,但没有用。我知道工件(父级)是在本地引用的并且不存在,但我不知道如何解决这个问题,有人可以帮助我吗?
错误是
Project build error: Non-resolvable parent POM for com.example:demo:0.0.1-SNAPSHOT: Failure
to transfer org.springframework.boot:spring-boot-starter-parent:pom:1.5.18.BUILD-SNAPSHOT
from https://repo.spring.io/snapshot was cached in the local repository, resolution will not be
reattempted until the update interval of spring-snapshots has elapsed or updates are forced.
Original error: Could not transfer artifact org.springframework.boot:spring-boot-starter-
parent:pom:1.5.18.BUILD-SNAPSHOT from/to spring-snapshots (https://repo.spring.io/
snapshot): repo.spring.io and 'parent.relativePath' points at no local POM
下面是pom.xml

希望它有效。
您使用的 Spring Boot 版本存在问题,因为它是构建版本。只需复制 1.X 的另一个发行版本并替换即可。
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.5.17.RELEASE</version>
<relativePath/>

如果您可以从浏览器访问 url https://repo.spring.io/snapshot/,则可能是 Maven 问题。 Maven 无法连接到存储库,这可能是由于:
下载的依赖项中的任何缓存问题。尝试删除本地依赖项,然后尝试此处提供的解决方案。
尝试 Maven 更新和 Maven Clean。
执行上述操作后尝试重新打开 IDE。
您的 pom.xml 没问题,看来是您的互联网连接有问题。检查您是否可以使用浏览器访问https://repo.spring.io/snapshot/。如果是,请检查是否需要配置代理服务器。如果没有,您应该联系您的互联网提供商。
