I have also come across the same issue and figuredout the issue here is the solution.
Lot of people assumes Eclipse and maven intergration is tough but its very eassy.
1) download the maven and unzip it in to your favorite directory.
Ex : C:\satyam\DEV_TOOLS\apache-maven-3.1.1
2) Set the environment variable for Maven(Hope every one knows where to go to set this)
In the system variable:
Variable_name = M2_HOME
Variable_Value =C:\satyam\DEV_TOOLS\apache-maven-3.1.1
Next in the same System Variable you will find the variable name called Path:
just edit the path variable and add M2_HOME details like with the existing values.
%M2_HOME%/bin;
so in the second step now you are done setting the Maven stuff to your system.you need to cross check it whether your setting is correct or not, go to command prompt and type mvn--version it should disply the path of your Maven
3) Open the eclipse and go to Install new software and type M2E Plugin install and restart the Eclipse
with the above 3 steps you are done with Maven and Maven Plugin with eclipse
4) Maven is used .m2 folder to download all the jars, it will find in
Ex: C:\Users\tempsakat.m2
under this folder one settings.xml file and one repository folder will be there
5) go to Windwo - preferences of your Eclipse and type Maven then select UserSettings from left menu then give the path of the settings.xml here .
now you are done...
