为什么我在 ~/.m2 下找不到我的 settings.xml？

Question

为什么我在 ~/.m2 下找不到我的 settings.xml？

注意：我目前运行 Apache Maven 3.3.9 在我的机器上。

Answer 1

There are two locations where a settings.xml file may live:

The Maven install: ${maven.home}/conf/settings.xml

The user’s install: ${user.home}/.m2/settings.xml

The former settings.xml are also called global settings, the latter settings.xml are referred to as user settings. If both files exists, their contents gets merged, with the user-specific settings.xml being dominant.

Tip: If you need to create user-specific settings from scratch, it’s easiest to copy the global settings from your Maven installation to your ${user.home}/.m2 directory. Maven’s default settings.xml is a template with comments and examples so you can quickly tweak it to match your needs.

Maven Settings Reference Guide

就这么简单

导航到 ${maven.home}/conf/settings.xml
并将您的 settings.xml 复制并粘贴到 ${user.home}/.m2/

Answer 2

默认没有settings.xml文件。

如果需要，您应该创建文件。

Answer 3

运行 mvn -X 获取有关您的 Maven 安装的信息，如下所示

阿帕奇行家 3.6.0 Maven 主页：/usr/share/maven Java 版本：11.0.2，供应商：Oracle Corporation，运行时：/usr/lib/jvm/java-11-openjdk-amd64 默认语言环境：en_IN，平台编码：UTF-8 OS 名称："linux"，版本：“4.15.0-47-generic”，架构："amd64"，系列："unix" 警告：发生了非法的反射访问操作警告：com.google.inject.internal.cglib.core.$ReflectUtils$1（文件：/usr/share/maven/lib/guice.jar）对方法 java.lang.ClassLoader.defineClass(java.lang.String,byte[], 的非法反射访问整数，整数，java.security.ProtectionDomain) 警告：请考虑将此报告给 com.google.inject.internal.cglib.core.$ReflectUtils$1

在以上信息中，您将能够找到 settings.xml 如下所示的位置

[DEBUG] Message styles: debug info warning error success failure strong mojo project

[DEBUG] Reading user toolchains from /home/test/.m2/toolchains.xml

为什么我在 ~/.m2 下找不到我的 settings.xml？

Why can't I find my settings.xml under ~/.m2?
