LT failing to connect to project suddenly

[Thomas]

Hi,

I am suddenly getting this error when I am trying to connect to a Clojure project. This even happens when trying to open an instarepl (not on a file):

Exception in thread "main" java.lang.ClassNotFoundException: lighttable.nrepl.core, compiling:(/tmp/form-init873585129780993961.clj:1:1010)

And I am not sure what has changed. I have deleted my ~/.config/LightTable dir and downloaded the latest LT as well. but no change :(

Any idea what I could be doing wrong? 

TIA

Hi,

I am still getting this problem and it stops me from using the instarepl :( I have reinstalled both 64 and 32 bit versions, but no luck there. I suspect that something in my environment changed, but I don't know what (I have noticed anything else).

Any idea what could cause this error to happen?

Thank,

Thomas

[Zubair Quraishi]

Newer versions of libraires, especially Om caused LightTable to stop connecting for me. Try going back to an older version of project.clj and see if that works

[Thomas]

Hi Zubair,

I even get this problem when I just want to open an instarepl with no project file(s) whatsoever. It has worked in the past so I think something in my environment changed, but as I don't really understand what the error means I don't know where to look either.

any pointers would be appreciated.

Thomas

Hey Thomas - 

Can you try updating "venantius/ultra" to the latest version (0.3.2) and trying again? There was a known bug that interfered with the Lighttable nREPL that was resolved recently.

Wait for LightTable 0.8, and it should fix this

[Thomas]

Woohooo!!!! This has fixed my problem!!!

Thank you very much!!!!

Thomas

[Thomas]

Talking of LT 0.8, do you know if there is a roadmap for it? what will be included and when?

Any pointers would be appreciated!

Thomas

[Zubair Quraishi]

Sorry, I am not sure when 0.8 is out. Maybe one of the LightTable team can update us.
