why is eclipse so many version behind the current version? I do not think it would hurt to update a little faster.
I have been using it like that almost every day for 15 years now.
My theory is that it is obviously because there is a way how to run Eclipse, without any issues and without the need of an officially tested debian package, so there is not huge demand.
Something like Netbeans doesn't need a debian package but Eclipse is split into lots of jar files that each depends on some shared libraries.
