Description
We want to run some processes in buildStart and watchChange in a plugin that I work on. The process needs to emit diagnostics and wish to use the rollup API to show the user those diagnostics, but it always throws when we use this.error outside the transform hook.
Is there a way to use this API and recover from the error in other hooks?
