xxxxx is the name of the stub jar. It is an ordinary jar file and added as a stub to my language and as a runtime library to my solution. I am trying to export my solution and language as a new IDE. But I could not resolve cannot find xxxxxx.jar in local layout error. I could execute root concepts of my solution, but I could not export a new IDE. I have tried to change localtion of jar file into several places under the project folder but nothing changed. Could you explain how can I deal with this error? Thanks a lot.
