java - Maven 在 Eclipse 中找不到 Artifact 命令 spring-boot-starter-parent

Question

当我尝试在 Eclipse 上运行任何 Maven 命令时出现错误。

错误信息:

[ERROR] Some problems were encountered while processing the POMs:
[FATAL] Non-resolvable parent POM for com.me.learn:first-application:0.0.1-SNAPSHOT: 
Failure to find org.springframework.boot:spring-boot-starter-parent:pom:2.1.5-RELEASE 
in https://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 and 'parent.relativePath' 
points at wrong local POM @ line 6, column 10

我检查的事情:

1. Project build error: Non-resolvable parent POM. Failure to transfer org.springframework.boot:spring-boot-starter-parent

2. 目录/home/{anonymous}/.m2/repository/home/{anonymous}/.m2/repository/org/springframework/boot/spring-boot-starter-parent

包含文件:spring-boot-starter-parent-2.1.5-RELEASE.pom.lastUpdated

手动清理存储库，并在 Eclipse 上运行干净。

我在 eclipse 中的 settings.xml 配置已设置到正确的位置，并且我的本地存储库的 eclipse 配置也已定义良好。

未定义代理。

有关我的配置和环境的信息:

我在 Ubuntu 上使用 eclipse。

• 强力/清理您的 ~/.m2/repository 目录/只需将其删除，它将在下一个版本中重新填充。
• settings.xml:检查存储库的“updatePolicy”。通常，版本从不检查更新，并且 SNAPSHOT 有默认值。我经常设置间隔:13(13分钟)
