Adding M2_REPO classpath variable in eclipse IDE

We know that what is use maven and how to use it from command prompt. Maven dependencies can be read from eclipse IDE also which maven exposes through M2_REPO classpath variable which points to maven’s local repository. This class variable must be added to eclipse ‘s class path variable on build path before using maven’s dependencies. Lets see how to do this:

Step 1) Go to menu Windows > Preferences


Step 2) Navigate to Java > Build path > Classpath Variables


Step 3) Define new classpath variable M2_REPO and point it to local maven repository


Step 4) Verify that variable has been added

  1. changed facet correctly, but to create web application from scratch mvn archetype:generate
    is stopping at number 242 :242 which creates, not a simple quick start web project but plugin project.
    which does not takes dependencies in pom file .
    so why mvn behavior is correct ?as it has so many options up till 710 , so what do ?
