Hi,

I have 2 same Eclipse instances running.
I want to open a file from shell, on one of them (not run new Eclipse instance!).
I can't figure out how to open the file on specific Eclipse instance.
when I'm running this:

eclipse --launcher.openFile <path/to/file>

it opens the file on my first Eclipse instance. How select the second one??

You probably can't. I've recently been trying to understand how this is supposed to work and found this old blog to be helpful:

I think the first Eclipse instance you run will always be the one that opens file... (Or maybe the last one you've run.) But in either case there's no way to tell the launcher which of the two already-running instances to use...

I see. Thanks for the info.
I experiencing sometimes weird things even with one instance though. Sometimes, I'm trying to open a file on it and it just doesn't work, instead a new Eclipse pops.
I this case, I close my running Eclipse and open it again. Then try again to open file from shell and it works.
So this lack of robustness drives me crazy.
Did this happen to you?

I've not found that it works reliably with the IDE itself. I have it working reliably for the installer but I'm having trouble getting the IDE itself to launch from a web link, and that uses this same mechanism as is used by the installer:

On which OS are you running?

I'm using: CentOS release 6.8

I think I figure out what caused the robustness issue. Let's say I have 1 instance running and openFile works for it.
When I open 2nd Eclipse instance, the openFile command works always on the 2nd one (the latter).
If I close it (2nd), then openFile stops working at all, as if the 1st instance is invisible to it.
So as conclusion, if I close the last opened Eclipse, I must open a new one, because any previous instance is ignored.
