Windows User Profile and Java

Question

I'm using Maven, and it stores local repository under user home folder.
I decided to move my user profile from C:\\Users\\Dany to D:\\Users\\Dany to save my SSD disk space. Also I changed several keys in windows registry.
All works fine but Maven still save artifacts to C:\\Users\\Dany\\.m2\\repository .

I know how to change local repository location in settings.xml .
But could somebody explain Maven's behaviour?

PS
IntelliJ IDEA also saves its data to C:\\Users\\Dany\\.IntelliJIdea11 .

UPD
System.getProperty("user.home"); returns C:\\Users\\Dany .

UPD2
set USERPROFILE in windows comand line says USERPROFILE=D:\\Users\\Dany .

UPD3
Question is about how Java gets user home folder location but not about how to set Maven repository location

Answer 1

On Windows Java gets the user.home property from the registry: HKEY_CURRENT_USER\\Software\\Microsoft\\Windows\\CurrentVersion\\Explorer\\Shell Folders\\Desktop then it removes the last folder.

For example: %userprofile%\\Desktop => %userprofile%

This is (will be) fixed in Java 8.

Until then, the solution is to add this into the environment variables:
_JAVA_OPTIONS:-Duser.home=%HOMEDRIVE%%HOMEPATH%

or in command line: set _JAVA_OPTIONS=-Duser.home=%HOMEDRIVE%%HOMEPATH%

I saw the solution in the comments of this page: http://www.timehat.com/javas-user-home-is-wrong-on-windows/

Answer 2

I got the question. Just run into the exactly the same issue. I found the answer here , then I also found the related bug entry too.

Answer 3

Put a settings.xml file into D:\\Users\\Dany.m2\\ and put something like this into your settings.xml

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
                      http://maven.apache.org/xsd/settings-1.0.0.xsd">

  <localRepository>D:/WhatEverLocationYouWant</localRepository

</settings>

Answer 4

First, you need to update the <localRepository> setting in the settings.xml in your home folder.

Next, you need to update the M2_REPO environmental variable to point to the new location. You may also need to set it for individual Eclipse projects , either by using maven itself or setting the environmental variable from the Eclipse settings.

Answer 5

If you have NTFS on both partitions, you could just create a symlink from D:\\Users\\Dany to C:\\Users\\Dany. Software won't see any difference.
