Where is Maven's settings.xml located on Mac OS?

if you install the maven with the brew

you can type the command("mvn -v") in Terminal

see Maven home detail

mvn -v
Apache Maven 3.5.0 (ff8f5e7444045639af65f6095c62210b5713f426; 2017-04-04T03:39:06+08:00)
Maven home: /usr/local/Cellar/maven/3.5.0/libexec
Java version: 1.8.0_121, vendor: Oracle Corporation
Java home: /Library/Java/JavaVirtualMachines/jdk1.8.0_121.jdk/Contents/Home/jre
Default locale: zh_CN, platform encoding: UTF-8
OS name: "mac os x", version: "10.11.5", arch: "x86_64", family: "mac"

After I have downloaded the binary from apache site I, have placed the extracted folder in /Library
So now the location of the settings.xml file is in:

/Library/apache_maven_3.6.3/conf

I installed mavaen using sdkman because of which the other proposed solution didn't work, as they are applicable if the installation is done via Homebrew or as a standalone binary.

for my solution I did "which mvn" in the terminal which returned: "/Users/samkaz/.sdkman/candidates/maven/current/bin/mvn"

Then after opening the path in a finder and looking around the above directory I found settings.xml in the below folder. "/Users/samkaz/.sdkman/candidates/maven/3.6.3/conf"

For macOS Monterey 12.0.1 and home-brew 3.4.7, it locates at /opt/homebrew/Cellar/maven/{version}/libexec/

I got this location from mvn -version, which gives me

Apache Maven 3.8.5 (3599d3414f046de2324203b78ddcf9b5e4388aa0)
Maven home: /opt/homebrew/Cellar/maven/3.8.5/libexec
Java version: 18, vendor: Homebrew, runtime: /opt/homebrew/Cellar/openjdk/18/libexec/openjdk.jdk/Contents/Home
Default locale: en_SG, platform encoding: UTF-8
OS name: "mac os x", version: "12.0.1", arch: "aarch64", family: "mac"

I think it's the best to use mvn -X so it should print you locations of settings being used effectively
