我刚刚下载了包含以下Pom.xml的{​​{3}}：

已安装的Maven版本如下（mvn -version：

Apache Maven 3.6.2 (40f52333136460af0dc0d7232c0dc0bcf0d9e117; 2019-08-27T17:06:16+02:00)
Maven home: /usr/local/Cellar/maven/3.6.2/libexec
Java version: 12.0.2,vendor: Oracle Corporation,runtime: /library/Java/JavaVirtualMachines/jdk-12.0.2.jdk/Contents/Home
Default locale: de_DE,platform encoding: UTF-8
OS name: "mac os x",version: "10.15.1",arch: "x86_64",family: "Mac"

如果我尝试从命令行运行man validate，则会收到以下错误消息

[ERROR] [ERROR] Some problems were encountered while processing the POMs:
[FATAL] Non-resolvable parent POM for com.iluwatar:model-view-controller:1.22.0-snAPSHOT: Could not find artifact com.iluwatar:java-design-patterns:pom:1.22.0-snAPSHOT and 'parent.relativePath' points at wrong local POM @ line 29,column 11

但是，如果我尝试在eclipse之外运行它，则一切正常。

为什么会这样？

他们使用不同的settings.xml吗？

在eclipse输出上调试mvn -X validate

[DEBUG] Reading global settings from settings.xml
[DEBUG] Reading user settings from /Users/myname/.m2/settings.xml

并调试来自终端输出的呼叫

[DEBUG] Reading global settings from /usr/local/Cellar/maven/3.6.2/libexec/conf/settings.xml
[DEBUG] Reading user settings from /Users/myname/.m2/settings.xml

地窖中的settings.xml没有条目，/Users/myname/.m2/settings.xml中的条目不存在，但是我找不到eclipse使用的条目（我认为是m2e插件）。
