John Casey closed MNG-3175.
---------------------------
Assignee: John Casey (was: Jason van Zyl)
Resolution: Fixed
I've started with the implementations of Exception that are handled in the
outermost layers of Maven (The embedder and cli), and encoded the specific
error conditions that lead to those exceptions into methods in the
CoreErrorReporter and ProjectErrorReporter interfaces, diving in up to two or
three exception-wrapping layers sometimes to get at an error that's more useful
to report on.
Obviously, as new behavior (or behavioral changes) evolve, it may become
necessary to modify the error reporter interfaces. However, the api should
probably be relatively stable, unless/until we get around to refactoring
DefaultMavenProjectBuilder, DefaultLifecycleExecutor, or DefaultPluginManager.
At that time, the aspects binding the reporter apis to the main body of code
will have to be adjusted to collect the proper context elements (project
instances, files, etc.).

>
> The problems that can occur during execution and project handing:
> - POM parsing errors
> - missing metadata
> - error retrieving metadata
> - version range violations
> - circular dependency violations
> - missing artifacts
> - error retrieving artifacts
> I have most of this handled in the ArtifactResolutionResult, but the
> ProjectBuildingResult and the MavenExecutionResult need some work to make
> sure that everything is passed through correctly. This is of the utmost
> important for embedding because it means from the UI that integrators can
> give users exact details as to problems that occur. Milos has really gone a
> long way to work around the fact we don't do this.
