I downloaded Eclipse-Juno Version: 4.2.0. But I am not able to install Android ADT on it. I am getting this error:
requires \'org.eclipse.wst.sse.core
Yes, I installed Juno and that package I installed did not come with WST either.
I fixed this same problem by adding Juno update site at http://download.eclipse.org/releases/juno/. You will find WST under "Web, XML, Java EE and OSGi Enterprise Development. For my own purpose I simply installed everything under this category and the problem went away.
