Re: A question about artifact resolution

Why is that? Surely the dependency plugin can't be appropriate for every case
of artifact resolution. If the artifact resolver API isn't usable as-is, or
is not documented fully I would expect that to be a problem to be addressed.
To expand on my problem, I am trying to write a wrapper around IzPack so that
installers can be created with custom panels. A project calling my plugin
would have configuration something like:
plugin
configuration
customPanels
customPanel
groupIdfoo.bar/groupId
artifactIdMyCustomPanel/artifactId
version1.0/version
/customPanel
/customPanels
/configuration
/plugin
If there's a way I can call the dependency plugin programatically from my
plugin, to pass along the parsed artifact information from the calling
project, I'd like to know. So far I have not found anything, hence my
decision to follow the documentation path that seemed to exist for calling
the resolver directly.
In fact, there appears no information I could find on how, if it is at all
possible, to embed plugins within plugins, in such a manner. Should the
general principle be something like?
FooPlugin foo = new FooPlugin();
foo.setBar1(xxx);
foo.setBar2(yy);
foo.execute();
where setBarX() methods mirror the plugin parameters?
By the way, there appears to be scant information on what components can be
used and how to use them property. Is there a definitive set of documentation
that I should be looking at? If I'm casting nasturtiums unjustly, I
apologise, but maven appears great from a user's perspective and very hard to
pull apart from a programmer's perspective, and that's mainly a documentation
issue, IMO.

Hi,
I'm trying to develop a plugin in which I want to resolve an
artifact so
that I can copy it somewhere special before using it. Not knowing
how (or if
it's even possible) to embed the dependency plugin's resolution
functionality, I decided to take what seemed like a simpler approach
and
perform the basic resolution myself, as according to
http://docs.codehaus.org/display/MAVENUSER/Mojo+Developer+Cookbook.
Unfortunately I get the following NPE:

at
com
.izforge
.izpack.maven.plugins.IzPackMojo.copyCustomPanels(IzPackMojo.java:174)
The code snippet that I wrote is as follows:
/** @component */
private org.apache.maven.artifact.factory.ArtifactFactory
artifactFactory;
/** @component */
private org.apache.maven.artifact.resolver.ArtifactResolver
resolver;
someMethod() {
Artifact panelArtifact =
artifactFactory.createArtifactWithClassifier(groupId, artifactId,
version,
jar, );
try
{
resolver.resolve(panelArtifact, remoteRepositories,
localRepository);
Do I need to create a variable in my plugin to store a component
similar to
the the ArtifactFactory and ArtifactResolver mentioned in the
cookbook? Is
there a better set of documentation that explains how to accomplish
such
tasks?

I suggest staying away from the artifact resolver directly. Why is that? Because from lots of experience I know you probably don't need it. Make your life simple, the dependency plugin is quite powerful. If you determine you want to use it directly the dependency plugin is a great example of how to use the APIs. Surely the dependency plugin can't be appropriate for every case of artifact resolution. If the artifact resolver API isn't usable as- is, or is not documented fully I would expect that to be a problem to be addressed.

So far I have not found anything, hence my decision to follow the documentation path that seemed to exist for calling the resolver directly. That's your solution. But your problem is putting some artifacts somewhere to be packaged up with an installer. If your requirement is to have all that code controlled from your plugin then use the resolver, but you can certainly solve your problem without it. The dependency plugin code would be a good place to start. It is a requirement to do it all within the plugin. Currently I have stuff scattered throughout the client POM, which does make use of maven-dependency-plugin. I need to hide all that behind an easy-to-use facade - a single plugin that allows you to specify (at least) where IzPack is, what custom panels your installer needs and where your IzPack config is. Replicating the process between numerous installer projects; where you need to copy assorted custom panels and other assorted setup for IzPack, invoking IzPack, and then cleaning up afterwards can be seriously messy and fraught with error. The more of that I can peel away from the user, the better. I started out looking at the code for maven-dependency-plugin, but it was so convoluted, that I couldn't get a handle on what it did, and how it initialised maven components as required. As I said, the cookbook has so far been the only place that spells out some basic steps on interaction with the maven infrastructure in a programmatic manner. If someone can give me a couple of pointers to more information, I would be grateful. snip Plugins depending on plugins is not a good thing. We learned the hard way with Maven 1.x where this was possible. It certainly wouldn't be my first choice for solving my problem :) Eric FooPlugin foo = new FooPlugin(); foo.setBar1(xxx); foo.setBar2(yy); foo.execute(); where setBarX() methods mirror the plugin parameters?
