Unknown JDBC Driver Class org.h2.Driver

[Jón Arnar Briem]

Recently I was playing around with versions of other plugins I was using and in the process I seem to have done something to my h2 driver and started getting this error when I tried to open Jira in my browser. Redownloading the repository to another folder and running Jira from there fixed the problem and I was able to continue developing my plugin. 

Today this error started popping up again and this time redownloading to another folder doesn't work (and is not really a solution if this keeps happening) .  I think this may be related to atlas-clean as I ran that command just before the error came up and I don't recall running it since I "fixed" the problem (not 100% sure though).

Does anyone have any clues as to what may be the cause? I've added the last part of the output from atlas-debug below for extra info.
