Why does Eclipse claim I have an outdated version of the ADT?

Issue

I recently upgraded to the latest version of the Android SDK using the SDK Manager.

Unfortunately it appears as if something went wrong. Every time I launch Eclipse now, I get the following error message:

If I click "Check for Updates", Eclipse does its thing and happily reports that there are no updates to install and that everything is up to date.

I can confirm that I have the latest version of the SDK installed:

What's going on here?

Solution

In the end, it seems like the problem was that I had:

http://dl-ssl.google.com/android/eclipse/

...instead of...

https://dl-ssl.google.com/android/eclipse/

Notice the https://.
