[che-dev] LSP4J version

[Jonah Graham <jonah@xxxxxxxxxxxxxxxx>]

Hi folk,

At the moment Che is using org.eclipse.lsp4j 0.2.0. For supporting VS
Code Debug protocol, we need to use lsp4j 0.4.0 (see
https://github.com/eclipse/che/issues/5508).

Is there anyone who is already looking at upgrading to Che to more recent lsp4j?

If I simply try to compile against the 0.4.0-SNAPSHOT (0.4.0 is not
released yet) then I get the error below, which AFAICT is an error
message from the Dto generator and probably due to some API/type
changes in lsp4j.

Thanks,
Jonah
