Do you have any ideas how it could be done? Unfortunately, upgrading Eclipse is not an option in my case.

Answer 1

I believe you must be trying the following URL in the update site:

http://download.eclipse.org/technology/m2e/releases

Try using:

http://download.eclipse.org/technology/m2e/releases/1.3

Answer 2

In your install manager, check "Contact all updates sites" . This should resolve the problem as sometimes dependencies come form different sites.
