An internal error occurred during: "Retrieving archetypes:". Java heap space when creating new Maven project

I am starting to learn Spring, So i am creating to new Maven project in eclipse. When i am trying to create a new Maven project , then it tries to retrieve archetype and gives the error ``` "An internal error occurred during: "Retrieving archetypes:" Java heap space ``` Steps that i followed : New -> Maven Project -> use default worksppace location (checked) and click Next -> waiting for retrieving archetype and error occurs. I have attached the screen shot for reference. Note : I have been trying to resolve this for hours, searched google and stack exchange, changed -Xmx size to 1024m from 512m in elclipse.ini file and tried to restart the eclipse, but that time eclipse refused to launch. Also 'Window -> Preferences -> Maven -> Download repository updates index on startup' is NOT enabled in my eclpise as suggested in other answer to similar question in stackoverflow to disable it. Please help me out with this.
