I'm having difficulty in installing ADT 1.7.0 Eclipse Plugin with this conditions :
the installation progress stop with detail :
"Cannot complete the install because one or more required items could not be found. Software being installed: Android Development Tools 17.0.0.v201203161636-291853 (com.android.ide.eclipse.adt.feature.group 17.0.0.v201203161636-291853) Missing requirement: Android Development Tools 17.0.0.v201203161636-291853 (com.android.ide.eclipse.adt.feature.group 17.0.0.v201203161636-291853) requires 'org.eclipse.wst.sse.core 0.0.0' but it could not be found"
Are there any solution to this ?
What helped in my case was installing Eclipse Indigo for Java EE Developers. Apparently, the classic version doesn't have everything that is required by ADT.
I also ran Eclipse as administrator but I'm not sure if it was required.
I had the same problem and finally solved it. I had to install Eclipse Indigo for Java EE Developers, and then I had to turn of my AVG 2012 for some time while the install was running.
This solved my problem.
