If you want to suppress all of the
unknown type warnings, then include the
--assertions_only parameter on the command line.
You may also see some error messages sent to syserr, like this:
Job found still running after platform shutdown. Jobs should be canceled by the plugin that scheduled them during shutdown: org.eclipse.jdt.internal.ui.InitializeAfterLoadJob
These messages can be safely ignored. These messages occur since Eclipse is being shut down early enough before all initialization jobs are complete. We'll be fixing this in future versions.
More to come
This is just a first pass at static checking. We are looking for feedback as to the best way to display failed assertions, or if there is anything else that can be improved. If there is significant interest, we can do the work to make it easy to create JUnit (or Spock!) tests for DSLDs, but we need to hear the feedback first.
