My point is that most of the people here are users and not interested in
plug-in development or knowledgeable about plug-in development.
Custom plug-ins are not required for development of standalone or web
applications in Java most of the time.
Most appear to be developed to support specific specific non-java
activities. I use one developed as a front-end for DITA document
production to simplify the use of the DITA-OT. I use another to simplify
the packaging of applications into an installer using IzPack.
These are pretty simple Maven plug-ins and likely do not include very
much coordination with or use of Maven internal methods.
I am not sure if there is a better forum for you to get the kind of help
that you need.
The kind of information that you seem to need is probably known by the
people who frequent the dev list but they are going to be pretty focused
on Maven development and may not welcome third-party development questions.
You might get some help by offering to add documentation to the code in
the dev list in return for specific questions. Certainly you are doing a
level of research into the examples, docs and code that could lead to
useful updates to the docs or examples.

Hi Ron - I'm not sure what you're telling me. I thought that the capability
to easily write custom plug-ins was part of the goal of Maven. If Maven
doesn't want people outside of Maven writing plug-ins, then you're right the
information I'm looking for isn't useful.
But the javadocs are published - they just aren't filled in. Examples are
published, but they're for Maven 2 and either don't work or are deprecated.
Basic tasks that *seem* to be within the scope of what Maven wants to do are
surprisingly difficult. That's frustrating.
The questions I've asked on this this have been as specific and technical as
I could make them. I'm not trying to waste anyone's time or not respect the
work that others have volunteered.

You are not using Maven; you are developing a custom plug-in.
That is a development activity so you should expect that it will be more
difficult than what other users need to do and you will need information
that is of no use to anyone else.
It appears that you are trying to extend Maven in a way that is outside what
Maven likes to do so you can expect that some information will be hard to
find outside the code.

Hey Russell - DependencyGraphBuilder seems to be for resolving the
dependencies that the project already has, i.e. in the
<project><dependencies> element. What I'm trying to do now is
configure additional dependencies used by my plugin at runtime outside
of the project dependencies.
I've used a lot of open source projects but I cannot remember one as
opaque as Maven. I'm looking through maven-dependency-plugin now to
see if I can glean any insights. It seems that plugin used the same
technique you did in its DefaultArtifactsResolver utility class. I'm
going to check out the project from svn to see how its initializing.

Hi Richard,
Believe me, I share your frustration. Like many open-source projects,
Maven is woefully under-documented. I've spent a significant amount of
time over the past months researching how to do things for the course
I've been writing, and also for the plugins I'm writing.
Mostly, I've been reading source code - especially the maven-supplied
plugins. The problem, of course, is figuring out what the "official"
and supported way of doing things is.
To resolve artifacts, I wound up using MavenProject, ArtifactResolver,
ArtifactFactory, and both the local and remote repositories. I didn't
even see DefaultDependencyGraphBuilder. If that's easier, I may
consider revising my approach.
Thanks,
Russ

Hi Russel -
The use case is simple - I've written a plug-in which takes in as
input a list of dependencies, just like any other plugin or the pom
itself. So, given a String representation of an artifact, how do I
resolve the artifact so I end up with a local File object I can load?
This API has seemed like total voodoo - I want to write a paper that
demystifies how to write plugins for maven3. I think I need to find
some time to sit with each of the principle author of maven3 and
publish what I learn.

+1 Anthony. The question is what is the preferred 3.x way of doing
+it, not
how to do it the old way. Unless the official answer is "do it the
old way because..."

hello, I 'm slightly confused about your answer Igor.
The other day I was wondering about how to keep a maven plugin doing
artifact resolution compatible with both maven 3.0 and 3.1 and
Robert answered me to use the maven dependency tree api :
http://stackoverflow.com/questions/17685441/can-a-maven-mojo-relying
-
o
n-aeth
er-be-compatible-with-maven-3-0-x-and-3-1-x#comment25769765_17686482
Now I am using something like that :
Artifact enforceArtifact =
defaultArtifactFactory.createArtifact(enforceGroupId,enforceArtifact
I
d
,enfor
ceVersion,"",enforceType);
MavenProject enforcePom =
mavenProjectBuilder.buildFromRepository(
enforceArtifact, remoteRepositories, localRepository);
DependencyNode rootNode =
dependencyGraphBuilder.buildDependencyGraph(enforcePom, new
CumulativeScopeArtifactFilter(Arrays.asList(Artifact.SCOPE_COMPILE,
Artifact.SCOPE_RUNTIME)));
and that works pretty well (I used to think relying on aether
directly was the best approach, until this change of package made my
plugins not maven
3.1 compatible)
Which approach would you consider the best then (when writing a
plugin doing dependency resolution) , using the Maven 2 API with
maven-compat or relying on maven-dependency-tree ?
Thanks for your answer !

Quick Q- what's the proper way to resolve an artifact in a Maven3
plug-in, e.g. where the artifact isn't already a managed dependency
in the project.
I found the Mojo Developer Cookbook (
http://docs.codehaus.org/display/MAVENUSER/Mojo+Developer+Cookbook)
but it gives the Maven2 technique, and the classes used are deprecated.
