Question

I’m setting up Eclipse for Android and when attempting to install the ADT plugin, I encounter the following error:

Edit: Notice the more complete error message here.

Cannot complete the install because one or more required items could not be found.
Software being installed: Android Development Tools 0.9.9.v201009221407-60953 (com.android.ide.eclipse.adt.feature.group 0.9.9.v201009221407-60953)
Missing requirement: Android Development Tools 0.9.9.v201009221407-60953 (com.android.ide.eclipse.adt.feature.group 0.9.9.v201009221407-60953) requires ‘org.eclipse.wst.sse.core 0.0.0’ but it could not be found

I’m on Win7 x64 and using Eclipse 3.5.

What could be wrong?

EDIT:

Did I not set my Path correctly? This is what the relevant part looks like.

Path…;C:\Users\Moshe\Development\android-sdk-windows\tools

Do I need to reboot after modifying the path?

EDIT:

I am looking to install this package:

org.eclipse.wst.sse.core 0.0.0

Did you go through this Installing the ADT Plugin?

1. Start Eclipse, then select Help >
   Install New Software.

2. In the Available Software dialog,
   click Add….1.

3. In the Add Site dialog that appears,
   enter a name for the remote site
   (for example, “Android Plugin”) in
   the “Name” field.2.

4. In the “Location” field, enter this
   URL:
   https://dl-ssl.google.com/android/eclipse/

5. Note: If you have trouble acquiring
   the plugin, you can try using “http”
   in the URL, instead of “https” (https
   is preferred for security reasons).4.

6. Click OK.

7. Back in the Available Software view,
   you should now see “Developer Tools”
   added to the list.6.

8. Select the checkbox next to
   Developer Tools, which will
   automatically select the nested
   tools Android DDMS and Android
   Development Tools.7.

9. Click Next.8.

10. In the resulting Install Details
    dialog, the Android DDMS and
    Android Development Tools features
    are listed.9.

11. Click Next to read and accept the
    license agreement and install any
    dependencies, then click Finish.
    Restart Eclipse.10.

This problem is caused because you have some plugins missing that are required by android tools. You can fix this by either installing a version of Eclipse which comes bundled with a lot of the eclipse plugins, or by tracking down the plugins yourself.

To do this, run eclipse, and go to Help->Install New software. Attempt to install the Android SDk, and you will be informed of what is missing, e.g:

*Missing requirement: Android Development Tools 0.9.6.v201002051504-24846 (com.android.ide.eclipse.adt.feature.group 0.9.6.v201002051504-24846) requires *‘org.eclipse.gef 0.0.0’ but it could not be found

So we need to install org.eclipse.gef . A quick Google for org.eclipse.gef, gives us http://www.eclipse.org/gef
Follow the link, and on the left hand side you will see a link for “Update Manger”, follow that link…

You then have a list of URI’s similar to the one for the Android plugin. Copy the one ending in “releases”( http://download.eclipse.org/tools/gef/updates/releases/ if you can’t be bothered ), and go back to eclipse. Paste this URI into the “Work with” box, as you did with the Android plugin, and install the components that come up.

Continue to do this until all of the Android dependencies are met, and the Android plugin will install. You will need to locate the correct locations for each of the required dependencies.
