I updated Eclipse with the new SDK tools (rev. 23), but now when Eclipse starts I receive the error:

This Android SDK requires Android Developer Toolkit version 23.0.0 or above. Current version is 22.6.3.v201404151837-1123206. Please update ADT to the latest version.

No updates were found with "Check for updates". If I try "Install new software", I can see version 23, but I can't upgrade due to the following error:

Cannot complete the install because of a conflicting dependency.

After download of the last ADT from the web site, it seems there's another problem.
