created branch 2-does-stable-update-site-still-usable-with-recent-eclipse-version to address this issue

It seems there is some successful install : https://marketplace.eclipse.org/content/lua-development-tools#metrics but don't know which version of eclipse is used.

I tested today with Eclipse IDE for Java Developers : Eclipse IDE 2023-09 R

I launched it, then add LDT update site : http://download.eclipse.org/ldt/releases/stable.
Then try to install Lua Development Tools and it failed because it missed old version of DLTK.

Missing requirement: 
   Lua Development Tools Core 1.3.0.201804031433 (org.eclipse.ldt 1.3.0.201804031433) 
requires 'osgi.bundle;
    org.eclipse.dltk.core [5.5.0,6.0.0)' but it could not be found

So I add the dltk v5.6 update site : http://download.eclipse.org/technology/dltk/updates-dev/5.6/
(In Eclipse menu : Help > Install New Software...
And it works for me, I can use LDT with last version of eclipse.

mentioned in issue #1

Hi Simon, I have trouble with this solution. When I open "Run" -> "Run configuration" -> "Lua Remote Application" I get an exception and I can not open this tab. Please can you check that on your side?

I didn't install the Remote Development Support. It is not mandatory to make LDT works. But I will give it a try.

I was able to install LDT Remote Development Support without error.
And I'm able to run Lua code remotely.

BUT I confirm with current version RSE (4.5.500.202305261020) I get and error when I tried to open "Run" -> "Run configuration" -> "Lua Remote Application" (unfold for details)

I tried to remove LDT Remote Development Support and Install an old verison of RSE using this updates sites :

• http://archive.eclipse.org/tm/updates/R3.x/3.5 (source : https://eclipse.dev/tm/downloads.php)

Then reinstall LDT Remote Development Support but same error...

So at least for now we can conclude that Remote Development Support just partially work...
