What can possibly go wrong with Maven

Rate this Message:
Hi,
I'm trying to collect everything that can go wrong inside Maven so that it can be clearly pointed out to a user. We currently have a mechanism that analyzes stack traces, isn't localized, and is not very friendly for embedding as everything is couched in the form of console output. Here's the list that I came up with so far and I want to make to make a mechanism that says exactly what's wrong. Anyone have anything else? I'm not trying to consider everything that happens in plugins. I've identified almost all the places where those errors occur and I would like them to surface at the top in a form that is useful to embedding. As a by product it's easy to produce console output for the CLI. I don't care if the try/catch is a mile long it's going to tell users exactly what happened when something goes wrong. I've pushed all console logging out of DefaultMaven and into the CLI. Moved the monitor into the core, but we still have console-centric logging in a bunch of the major components which I should be able to purge by the release of 2.1-alpha-1. Here's the list: - bad command line parameter - malformed settings - malformed POM - local repository not writable - remote repositories not available - artifact metadata missing - extension metadata missing - extension artifact missing - artifact metadata retrieval problem - version range violation - circular dependency - artifact missing - artifact retrieval exception - plugin metadata missing - plugin metadata retrieval problem - plugin artifact missing - plugin artifact retrieval problem - plugin dependency metadata missing - plugin dependency metadata retrieval problem - plugin configuration problem - plugin execution failure due to something that is know to possibly go wrong (like compilation failure) - plugin execution error due to something that is not expected to go wrong (the compiler executable missing) Thanks, Jason ---------------------------------------------------------- Jason van Zyl Founder and PMC Chair, Apache Maven jason at sonatype dot com ---------------------------------------------------------- --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscribe@...

But Maven can't tell the difference between "doesn't need a POM" (archetype, which can use it and add a <module> if it exists) and "shouldn't use a POM" (install-file), so this isn't an error condition. It's something the plugin developers need to take into account. - Brett -- Brett Porter - brett@...

I am not too familiar with the internals, but I assume that the evaluation of the POMs takes place before the goal is called. If the Mojo has already the possibility to supress the traversal of the modules, then I agree and it's a simple bug in the goal. - Jörg --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscribe@...

That's one of the things @aggregator is used for (though it has had problems as Brian showed).

- Classloader problems: often difficult to debug them when artifacts are coming from different
"transitive sources". Would be great to have a better way to display a trace of the dependency tree, without being swamped by all the non-dependency "noise". Maybe a new debug flag (different from -X and -e) would help here.
