(1) Import "grapher" in Eclipse after downloading it from git repo here https://github.com/17patelumang/GenomeSimulator
(2) In Eclipse,
select Help-->Install New Software--> In "Work With" paste this link http://download.eclipse.org/tools/gef/updates/milestones/ -->(if one cant see GEF(Graphic Editing Framework) under name then , Add-->Location-->http://download.eclipse.org/tools/gef/updates/milestones/) -->Under "Name" check mark the GEF tab-->Next -->Next--> Accept-->Finish
It will take time to install & after restarting eclipse , now most of the error will be solved.
(3) Right click --> Refresh (Now here check if there any error, most version of eclipse wont show error however if it does (esp in eclipse version 'Luna') then it will in 'View.java' (src/com.grapher/View.java) at line 23 "import org.eclipse.osgi.framework.internal.core.ConsoleManager;" & in plugin.xml (plugin.xml tab) last plugin.
) . Please comment out both the things in View.java and plugin.xml . I have already commented out this on git repo now , however for other version of eclipse even if it is not commented its fine because this dependency is not used in application.
(4) Right click on grapher folder --> Run as --> Eclipse Application and it will run.
To check here click on File-->Open--> Path to admixture.txt(sample file on github to see the running).
