Sometimes you have to amend the Maven settings.xml file to add a proxy or various repositories.
I had to do that a couple of days ago when experimenting with a 3rd party library.
What I sometimes forget, is that there are two settings.xml files. Now I shouldn’t forget this, because it is quite clear on the Maven Apache site.
But I do.
The settings.xml file in
%M2_HOME%/conf/settings.xmlis the global settings.- your
.m2user directory is your user-specific settings.- This file doesn’t exist until you create it, which might explain why I forget about it.
Duplicate settings in the user-specific file, override the settings in the global settings.
I was reminded of this because of the permission schemes in Windows 7 which wouldn’t let me save my global settings without upping my permissions to admin.
You can see the combined settings if you issue the command:
mvn help:effective-settings
