I have tried installing m2e-wtp plugin but getting below error:-

I found the solution myself.
You need to first install the correct version of m2e-eclipse plugin.
http://download.eclipse.org/technology/m2e/releases/1.4/1.4.1.20140328-1905/
Then installed the m2e-wtp plugin version:-
http://download.eclipse.org/m2e-wtp/releases/kepler/1.0.0/1.0.1.20130911-1545/m2e-wtp-jpa/
and same as above link for m2e-wtp
This resolved the error.
