ADT Plugin can't install: Missing requirement: Android Development Tools

Question

I tried to install ADT plugin on eclipse helios windows 64 bits classic. I got this error:

Cannot complete the install because one or more required it

Answer 1

The eclipse version is old, you need to provide the org.eclipse.wst.sse.core 0.0.0 library to it.

See instructions here : http://code.google.com/intl/es/eclipse/docs/faq.html#wstinstallerror

or , i would recommed to upgrade to Eclipse Indigo, which won't have this problem..
