Nested artifacts
Is there a simple way to unpack a dependency then unpack an artifact that lives inside that dependency?
We have several third party utilities stored in Nexus and referenced as dependencies, but I'd like to unpack a rar that is nested within a zip.
Is there a maven 2 way or do I just rely on an ant task?
Thanks in advance!

Hi,
> So the first part of the problem is the zip contains multiple rar files, but only one needs to be unpacked and tinkered with.
the maven-external-dependency-plugin might fit the bill:
<http://code.google.com/p/maven-external-dependency-plugin/>. If the RAR
file is not found in the local repository, the plugin tries to download
the ZIP file, extracts the RAR, and installs it in your local
repository. You would then bind dependency:unpack to a later phase,
referring to the RAR artifact just installed. (I use this plugin in a
similar way, with dependency:copy:
<https://bitbucket.org/scalabench/scalac-dacapo-benchmark/src/4dac488d735c/pom.xml#cl-246>.)
The only issue
<http://code.google.com/p/maven-external-dependency-plugin/issues/detail?id=8>
I have found so far with the maven-external-dependency-plugin is that it
doesn't work well with Maven 3 if the artifacts you want to extract
(RARs in your case) are among the project dependencies. Unlike Maven 2,
Maven 3 seems to resolve all project dependencies first, before any
lifecycle phases are executed; thus, the
maven-external-dependency-plugin doesn't get a chance of installing the
missing dependencies first. This is not a problem when using
dependency:copy or dependency:unpack, however.
I hope this helps.

Thanks all who have replied!
So the first part of the problem is the zip contains multiple rar files, but only one needs to be unpacked and tinkered with.
You can't put a dependency on anything that doesn't exist when maven tries to validate the poms and resolve the dependencies. So what I ended up doing is just putting a dependency unpack on the zip then later binding an ant call to unzip the rar.
What I don't want to have to do is say, "Ok, so we've decided to update this 3rd party thing, now upload these 24 artifacts into nexus". I'd rather say, "Ok, just zip it up and stuff the whole thing up there".
Thanks again all - I appreciate all the suggestions and feedback!
P.S. - Maybe if/when I have absolutely nothing to do, I'll submit a patch that offers a recursive unpacking of a given dependency with includes/excludes - that would have been the ultimate solution for me ;-)

I would probably unpack the zip myself and deploy the rar artifacts to
the repository once, rather than trying to do it every time you build.
How frequently do the third party utilities change?

Sorry, let me rephrase it all a bit (keep in mind that I am not saying
it works, I am currently unable to test anything in Maven!):
You need to configure the dependency-plugin to extract the ZIP and only
AFTER that, try to unpack the RAR -- in a separate step. I believe there
are a couple of phases that run WITHOUT Maven checking for the
dependencies and crying about a missing one.
If I can get around to playing with my laptop a bit, I might test this
out and report back to you. In the mean-time, feel free to try this.
One question that just popped into my mind: do you have to be in a
certain phase when extracting or is any phase right for you?

Hmmm - kinda.
Again, I'd like to unpack a rar that is nested within a zip.
The dependency unpack bits even if it's a system scoped dependency will try and resolve that and it won't be there.
:-/
I think I just need to "shell out" to ant...

Not 100% sure about this one, but you could try it with the
dependency-plugin [1]. I believe it does not allow system-dependencies
in its configuration, but judging from the sentence
"The artifact version is optional. If not set, the plugin will attempt
to resolve it from the project dependencies and then the
dependencyManagement section." [2]
I think that if you add that dependency to your
dependency(-management)-list with the correct path, it should work.
