Are you running multiple Eclipse Environments on your developer workstation? Or on your laptop? I do. Let’s consider a scenario with two different Eclipse workspace with different custom maven settings.
Why is that case? Let’s understand.
- What if your
Workdevelopment environment or framework is based on Eclipse? In company environment, all of your required project’s .jar files must be located inprivaterepositories and you have customsettings.xmlfile with very specific repositories. - And on opposite side, for standard eclipse/maven usage – all
publicmaven repositories are available to us for free without any restriction.
Definitely we need two different settings.xml files for above usage. If you are new to maven and eclipse setup then follow these steps to setup maven correct way on you laptop/desktop.
NOTE: settings.xml is not required (and thus not auto created in ~/.m2 folder) unless you want to change the default settings. In our case we do have different settings for work and personal workspace.
If you also have below questions then you are at right place:
- eclipse – Why maven settings.xml file is not there?
- How do I link to my settings.xml file from Eclipse
- Development project with Eclipse and Maven
- m2e users – where is settings.xml file?
- maven settings.xml file download
- eclipse embedded maven
- eclipse maven settings.xml location
What is settings.xml file?
settings.xml is a file which provides all configuration for maven which internally referenced in your maven project‘s pom.xml file. When you add dependencies into pom.xml file maven internally downloads required .jar file and put it under the folder which is mentioned in settings.xml file.
Where can I find settings.xml file?
- Windows machine: C:\Users\<UserName>\.m2\settings.xml
- On Mac OS X: /home/<UserName>/.m2/settings.xml
What is a default content of settings.xml file?
Just update <UserName> in below file with your system’s username.

How can I use two different settings.xml files for personal and work related repository?
Step-1
- Go to
~/.m2folder - Put work related
settings.xmlfile and providelocalRepositorypath: - <localRepository>/Users/<UserName>/.m2/
work</localRepository>
Step-2
- Go to
~/.m2folder - Put local eclipse related
crunchify-settings.xmlfile and providelocalRepositorypath: - <localRepository>/Users/<username>/.m2/
repository</localRepository>
What is you don’t have correct settings.xml file?
Eclipse throws number of different errors:
Once you have correct settings.xml file. Try performing below steps and all errors should go away.
- Click on
ProjectMenu - Click on
Clean...and clean you project - Right click on project
- Click on
Maven - Click on
Update Project...(below diagram)
