The error message says that there is no SWT widget kit available on your installation.

You did not tell it, but are you attempting to run Eclipse on Raspberry Pi?
Eclipse may be too heavy for a Pi. There are lighter weight IDEs for Pi, e.g. Anjuta.

It's not a matter of being heavy, it's a matter of eclipse.org building for x86_64
processors, not the 64-bit ARM processor used in the Raspberry Pi 3 and
newer. The only moderately recent build for the Pi that I know of is part of the
Fedora ARM distributions.

Even a fully up to date EL6 installation might not be compatible. The current
release targets 7.5 and specific versions of gtk.

I am getting the same error on Ubuntu 18.04, which is listed as a release target.

Which Ubuntu packages are required (especially libswt-gtk) for Eclipse SDK 4.10 to work?

I cannot find libswt-pi4-gtk.so in Ubuntu 18.04 packages. It is not included in

eclipse-SDK-4.10-linux-gtk-x86_64/plugins/org.eclipse.swt.gtk.linux.x86_64_3.109.0.v20181204-1801.jar

Do I need to compile it by myself?

If you installed Eclipse from the Ubuntu repository, just remove it using the package manager (apt, muon or whatever you're using).

This is what works on my 64 bit Kubuntu 18.04LTS:

If you do not have it yet, install the Oracle JDK using the instructions from <https://www.digitalocean.com/community/tutorials/how-to-install-java-with-apt-on-ubuntu-18-04>, from 'Installing the Oracle JDK'.

Get the Eclipse installer from the Eclipse download sites and use it to install Eclipse with CDT. You can use the 'Install New Software' to add other flavors to it.

Excellent, it works now!

I am using Eclipse 4.10 and Oracle JDK 8 installed from tar/zip-distribution.

The problem turned out to be a mixture of OpenJDK's installed from Ubuntu repos and using Nix package manager. I cleaned the JAVA_HOME and PATH pointing to these JDK's, and was able to start Eclipse 4.10 using OpenJDK (both from Ubuntu and Nix, with JAVA_HOME and PATH set correctly to either one).

Thanks!
