In the first snip, I need to get a list of all dependencies for a
project in a tree so that I can add some dependencies to a classpath
to execute a child java process. The second snip is used to resolve
artifacts which are not configured directly as dependencies, but
defined similar to how the dependency plugin lists <artifactItems>.
I have a few different plugins that need this and I want to put all
of the code to do it into a helper component so it is easier to reuse
and maintain. I also need to be able to get all of the transitive
deps for an <artifactItem> too. For example, in the Geronimo car
plugin, there is a goal which packages a car, and in that jar we need
to specify a classpath. The classpath needs to contain a sub-set of
the dependencies of the module which is building the car... and since
in m2 there is no mechanism to annotate dependency elements with
custom data to allow my plugin to use that to determine which to
include, I have to do something similar to the dependency plugin and
define nested artifactItem elements in the plugins config. Right now
it lists all of the deps, but I would like to list a few deps and
pick up the rest as transitive deps of those few artifacts.
So I was building a DependencyHelper plexus component, which defines:
DependencyTree getDependencies(MavenProject)
DependencyTree getDependencies(Artifact)
Then mojo's that need this, can use use the helper component and not
need all of the other bits that are needed to make this work. So
far, at least for getDependencies(MavenProject) this works, except
that I need to pass in the ${localRepository} reference from the
mojo... which means the mojos that use it need to define fields for
the helper and the ${localRepository}. I'd like to avoid needing
those mojos to know anything about the ${localRepository}.
I've got some similar problems with other components, where I'm
trying to put commonly used code into helper objects or components to
share them between my mojos but its a bit of a pain right now as
helper objects don't get @parameter bits processed and that some of
the needed objects are not available (AFAIK) to be used in @component
references.
I'm also a little confused as there seem to be several different ways
(that have been suggested to be by folks in #maven) to get a tree of
a specific projects deps transitively or the same for a specific
artifact.
But, I was able to get something to work with the collector.
Anyways, as we start making more and more plugins to help with the
Geronimo build, its is becoming more and more important to put the
shared helper code into components to allow them to be easily shared
between plugin modules and easier to maintain.

No I did not send that message 5 times.
I need the localRepository for calls like:
<snip>
artifactCollector.collect(
project.getDependencyArtifacts(),
project.getArtifact(),
managedVersions,
getArtifactRepository(), // ${localRepository}
project.getRemoteArtifactRepositories(),
artifactMetadataSource,
null,
Collections.singletonList(listener));
</snip>
or:
<snip>
getArtifactResolver().resolve(artifact, getProject
().getRemoteArtifactRepositories(), getArtifactRepository());

The settings object (which contains the local repo) is not a
component,
so you can't inject that.
You could re-parse the settings.xml yourself, but that's not a nice
solution.
I think you're stuck with passing the settings or local repo to
the component
on method calls, or call a setter.
Btw, why do you need the local repository? If it's for artifact
resolution you could also a component from maven-artifact(-manager).

Anyone know how to get the "${localRepository}"
ArtifactRepository from a Plexus component... not a mojo.
More specifically I have created a new component, which I inject
into my mojo (with @component and a <component> role defined in
plexus/components.xml) and I want that injected component to
have access to "${localRepository}", but I don't want to define
that in my mojo and pass it in to the component each time it
needs it.
Anyone know how to do this?
Thanks,
