How to change Maven local repository in eclipse

Question

I m importing a multiple-module Maven project from the root directory on a shared drive on another server A  On server A  mvn install will run successfully  and Maven is set up properly with repository  and settings xml in  home user  m2   However  after I imported the project into Eclipse  STS actually  on my workstation PC  I can t get mvn build  I have the m2e plugin installed  to run  mostly due to missing dependencies from other modules  I realized that Eclipse is using settings xml and repository  on my workstation PC  so there won t be any module build installed in the  m2 cache   I m trying to modify Maven to use the  m2 directory on server A  I can only set settings xml to the one on server A  but I cannot change the local repository  The only option I have is to  re-index    Is there a way to change the local repository to the one on server A  or is there a better way to have code on one server  and edit build test on Tomcat on another PC

In newer versions of Eclipse the global configuration file can be set in

Windows > Preferences > Maven > User Settings > Global Settings

Don't beat me why global settings can be configured in user settings... Probably because of the same reason why you need to press "Start" to shutdown your PC on Windows... :D

In Eclipse Photon navigate to Windows   Preferences   Maven   User Settings   User Setting  For  User settings  Browse to the settings xml of the maven  ex  in my case maven it is located on the path C  Program Files Apache Software Distribution apache-maven-3 5 4 conf Settings xml  Depending on the Settings xml the Local Repository gets automatically configured to the specified location

In general  these answer the question   How to change your user settings file   But the question I wanted answered was how to change my local maven repository location   The answer is that you have to edit settings xml   If the file does not exist  you have to create it   You set or change the location of the file at Window   Preferences   Maven   User Settings   It s the User Settings entry at     It s the second file input  the first with information in it     If it s not clear   redacted  should be replaced with the local file path to your  m2 folder     If you click the  open file  link  it opens the settings xml file for editing in Eclipse     If you have no settings xml file yet  the following will set the local repository to the Windows 10 default value for a user named mdfst13     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                               https   maven apache org xsd settings-1 0 0 xsd  gt      lt localRepository gt C  Users mdfst13  m2 repository lt  localRepository gt   lt  settings gt    You should set this to a value appropriate to your system   I haven t tested it  but I suspect that in Linux  the default value would be  home mdfst13  m2 repository   And of course  you probably don t want to set it to the default value   If you are reading this  you probably want to set it to some other value   You could just delete it if you wanted the default     Credit to this comment by  ejaenv for the name of the element in the settings file    lt localRepository gt    See Maven  mdash  Settings Reference for more information     Credit to  Ajinkya s answer for specifying the location of the User Settings value in Eclipse Photon     If you already have a settings xml file  you should merge this into your existing file   I e   lt settings and  lt localRepository gt  should only appear once in the file  and you probably want to retain any settings already there   Or to say that another way  edit any existing local repository entry if it exists or just add that line to the file if it doesn t     I had to restart Eclipse for it to load data into the new repository   Neither  Update Settings  nor  Reindex  was sufficient

location can be specified in Maven- Installation -  Global Settings  settings xml

I found that even after following all the steps above  I was still getting errors saying that my Maven dependencies  i e  pom xml  were pointing to jar files that didn t exist    Viewing the errors in the Problems tab  for some reason these were still pointing to the old location of my repository  This was probably because I d changed the location of my Maven repository since creating the workspace and project   This can be easily solved by deleting the project from the Eclipse workspace  and re-adding it again through Package Explorer -  R Click -  Import    -  Existing Projects
