Hey guys,

For some reason, i cannot launch my runtime eclipse anymore...it was still working yesterday.
now if i click on the Launch Runtime Eclipse button, eclipse logo will first pop up as if it's launching, after the logo disappears, i'm expecting the editor to show up, but it doesn't.
I checked my running processes, it's not there either.

I don't get new errors when launching runtime eclipse, but i do have errors when loading my xtext projects.

Hi

Not clear what you mean by "Launch Runtime Eclipse button".

The early startup of Epsilon has been reported. It should be irrelevant.
But it also has a bad model registration.

The other message looks like you've trimmed a vital line of information.

I suspect that you have a tool that is intolerant of bad registrations
running at startup.

Suggestion, if you want to continue with the current installation. Move
org.eclipse.epsilon.emf.dt...jar to some saved area, so that you can put
it back again if you want to.

Regards

Ed Willink

Hi Ed,

Thank you for your fast reply.

I'm developing a DSL, and i want to test it in my runtime environment where the language is recognized. The Launch Runtime Eclipse is just a configuration to launch a new eclipse application.

Indeed i think the error messages should be irrelevant to my problem.
I just quickly created a new xtext project to test whether the runtime eclipse can be launched, and it can be. So now i'm guessing it has something to do with my own project. But i don't get any error messages when it failed to launch a new eclipse application.
