回答1:
Click Help-> About Eclipse -> Installation Details -> Installed Software
Find out your software
Click uninstall
回答2:
Download fresh copy of Eclipse Kepler. If you want m2e, use this link http://eclipse.org/m2e/download/
many other m2e plugins are old and stopped development.

Actually if you wish to get rid of m2e, you need to remove all packages and directories containing m2e string in eclipse installation's plugin folder. Removing them from workspace doesn't do much good (they are recreated if needed).
I tried this out in Luna and all m2e integrations (plugins and features) were removed...
Now if you still wish to use maven (but not m2e plugin), you just need to create external tool entries for each maven operation you wish to use.

You cant download the java EE version , you have to download Eclipse Standard, and use the update site to select java EE plugins you want, in that case you do not select m2e integration

Remove folders:
.metadata.plugins\org.eclipse.m2e.core\
.metadata.plugins\org.eclipse.m2e.logback.configuration\
From this
