Eclipse plugin cannot be installed

[Magnus]

Hi,

the installation of the eclipse plugin fails for me.

I downloaded the latest eclipse version (indigo, 3.7) and added the following update site:
http://dl.google.com/eclipse/plugin/3.7

When selecting all packages and starting the installation, I get the following message:

"The operation cannot be completed. See the details."

Well, the details are:
"Your original request has been modified.
  "WindowBuilder Core" is already installed, so an update will be performed instead.
Cannot complete the install because one or more required items could not be found.
  Software being installed: Google App Engine Tools for Android 2.4.2.relr37v201110112027 (com.google.gdt.eclipse.mobile.android.feature.feature.group 2.4.2.relr37v201110112027)
  Missing requirement: Android Cloud Tooling 2.4.2.relr37v201110112027 (com.google.gdt.eclipse.mobile.android 2.4.2.relr37v201110112027) requires 'bundle com.android.ide.eclipse.adt 12.0.0' but it could not be found
  Cannot satisfy dependency:
    From: Google App Engine Tools for Android 2.4.2.relr37v201110112027 (com.google.gdt.eclipse.mobile.android.feature.feature.group 2.4.2.relr37v201110112027)
    To: com.google.gdt.eclipse.mobile.android [2.4.2.relr37v201110112027]"

What can I do?

(I selected Eclipse Java, not Java EE. Is this important? What is recommended for GWT?)

Thanks
Magnus

Thanks,

I managed it by first installing/upgrading some eclipse packages... Don't know why, but it works now...
