Maven在eclipse spring-boot-starter-parent中找不到工件命令

Question

当我尝试在Eclipse上运行任何Maven命令时，会出现一个错误。

错误消息：

[ERROR] Some problems were encountered while processing the POMs:

resolution will not be reattempted until the update

• 暴力/清除您的~/.m2/Repository目录/只需删除它，它将在下一个构建中重新填充。
• settings.xml：签入存储库的“updatePolicy”。通常，发行版从不检查更新，SNAPSHOT有一个默认值。我经常设置间隔：13（13分钟）
