Maven - Where is Maven local repository?

The maven local repository is a local folder that is used to store all your project’s dependencies (plugin jars and other files which are downloaded by Maven). In simple, when you build a Maven project, all dependency files will be stored in your Maven local repository.
By default, Maven local repository is default to .m2 folder :

1. Unix/Mac OS X – ~/.m2
2. Windows – C:\Documents and Settings\{your-username}\.m2

1. Update Maven Local Repository

Normally, I will change the default local repository folder from default .m2 to another more meaningful name, for example, maven-repo.
Find {M2_HOME}\conf\setting.xml, update localRepository to something else.

{M2_HOME}\conf\setting.xml

<settings>
  <!-- localRepository
   | The path to the local repository maven will use to store artifacts.
   |
   | Default: ~/.m2/repository
  <localRepository>/path/to/local/repo</localRepository>
  -->

<localRepository>D:/maven_repo</localRepository>
