java - 不可解析的父 POM

Question

我收到以下错误:

The project com.TestOne:test:0.0.1-SNAPSHOT (C:\Users\KroemerT\eclipse- 
workspace\KeydoxWeb\pom.xml) has 1 error
[ERROR]     Non-resolvable parent POM for com.TestOne:test:0.0.1-SNAPSHOT: 
Could not transfer artifact org.springframework.boot:spring-boot-starter- 
parent:pom:2.0.6.RELEASE from/to spring-snapshot 
(http://repo.spring.io/snapshot): connect timed out and 
'parent.relativePath' points at no local POM @ line 14, column 13 -> [Help 
2]

我犯了一个明显的错误，删除了 .m2 中的存储库，现在出现了上述错误。有什么办法可以解决这个问题吗？

我的 POM 是:

Answer 1

http://repo.spring.io/snapshot/org/springframework/boot/spring-boot-starter-parent/中没有版本1.4.4.RELEASE 。

我会选择org.springframework.boot:spring-boot-starter-parent:2.0.6.RELEASE来自 Maven Central，一般建议是在 Maven Central 中搜索最新版本，因为教程往往会随着时间的推移而过时。
