Setting Environment Variable

Next step would be to set up environment variables related to Maven. Open Environment variable dialog box and add below env. variable.

Env. Variable 1:

Variable Name : “M2_HOME”

Variable Value : C:\Maven\apache-maven-3.0.4 (Assuming you have extracted the maven folder @ C:\Maven)

 

Env. Variable 2:

Variable Name : “M2”

Variable Value : %M2_HOME%\bin

 

Note*: Maven requires JDK to be installed properly.  Check if JAVA_HOME environment variable is properly set or not.

 

Check Maven Installation

After setting all parameters, its time to check if Maven is installed properly or not.

To check installation of Maven open command prompt and type below command.

mvn -–version

Output of the above command should be something like below.

Maven Version Check

If output is “’mvn’ is not recognized as an internal or external command, operable program or batch file.”

Then there should be some problem while setting the path of maven folder. You can check with path environment variable. Check if all path is set properly or not

Maven Repository Introduction

To resolve the dependency of a project Maven requires multiple JARs (Framework specific Jars or Project Jars). Maven will look for these Jars in certain locations these locations are called Repository (Maven Specific Terminology).

Maven has 3 different type of repository.

  • Local Repository
  • Central Repository
  • Remote Repository

Local Repository Introduction

Maven local repository is a folder on local system which is used to store project’s dependencies (Jars). Whenever you try to build a project Maven will try to download all the required Jars in Local Repository (If it is not already present in Local Repository). Maven tries to avoid connecting remote system for multiple build of the same application by using Local Repository.

Creation of Local Repository

Local Repository will get created whenever you run any maven command for the first time.

Default Location of Local Repository

Maven default local repository will be created in user home directory with name “.m2”.

In windows it should be: echo %USERPROFILE%\.m2

In Unix or Linux it should be: echo $HOME\.m2

Custom Local Repository Location

To change the location of Default Local Repository you need to change the maven’s “settings.xml”, which will be located @ %M2_HOME%\conf.

In settings.xml try to find below lines.

 

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

Local Repository path part is commented, provide the path of your custom directory and save it.
