Missing maven m2 folder

Question

AFAIK maven does not have an installer for Windows  you simply unzip it wherever you like  as explained here   However in many places there are references to a  m2 folder under the user folder  in Win7 I would guess it to be by default at C  Users  m2  Alas I do not have that folder  Is there some command to create this folder  Am I missing something basic

When you first install maven   m2 folder will not be present in C  Users   user  path  To generate the folder you have to run any maven command e g  mvn clean  mvn install etc  so that it searches for settings xml in  m2 folder and when not found creates one   So long story cur short  open cmd -  mvn install  It will show could not find any projects Don t worry maven is working fine  P  now check your user folder   P S  If still not able to view  m2 folder try unhiding hidden items

On a Windows machine  the  m2 folder is expected to be located under   user home   On Windows 7 and Vista this resolves to  lt root gt  Users  lt username gt  and on XP it is  lt root gt  Documents and Settings  lt username gt   m2  So you d normally see it under c  Users Jonathan  m2   If you want to create a folder with a   prefix on Windows  you can simply do this on the command line    Go to Start- Run Type cmd and press Enter At the command prompt type md c  Users Jonathan  m2  or equivalent for your   user home  value     Note that you don t actually need the  m2 location unless you want to create a distinct user settings file  which is optional  see the Settings reference for more details    If you don t need a separate user settings file and don t really want the local repository under your user home you can simply set the location of your repository to a different folder by modifying the global settings file  located in  conf settings xml    The following snippet would set the local repository to c  Maven repository for example    lt 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  gt     lt localRepository gt c  Maven repository lt  localRepository gt

Use mvn -X or mvn --debug to find out from which different locations Maven reads settings xml  This switch activates debug logging  Just check the first lines of mvn --debug   findstr  i  c using  c reading     Right  Maven uses the Java system property user home as location for the  m2 folder   But user home does not always resolve to  USERPROFILE   m2  If you have moved the location of your Desktop folder to another place  user home might resolve to the parent directory of this new Desktop folder  This happens when using Windows Vista or a more recent Windows together with Java 7 or any older Java version   The blog post Java   s    user home    is Wrong on Windows describes it very well and gives links to the official bug reports  The bug is marked as resolved in Java 8  The comment of the blog s visitor Lars proposes a nice workaround
