A local repository does not have the same metadata as a remote
repository. Plugins especially are very picky about metadata.
Check the list archives, there was some discussion in times past about
a script to modify the metadata of a local repo so it would work as a
remote one.
The easier solution by far will be to run a repository manager locally
and let it proxy everything you need, then move *that* repository
(which will have the correct format) off to the other machine.

I will second what Wendy said, and also say that the free version of Nexus is incredibly easy to set up, manage, and use.
I hope the Sonatype people are making money, because they deserve to. They've made a real quality product.

Your best bet is to do as follows.
Set up a clean Nexus MRM (or any of the other MRMs) caching central
Blow away your local repo
Do a full clean build
Now you can take the central cache that Nexus MRM has built and that is a
valid remote repository... and nexus will have cleaned up the remote
metadata for you as well

Re: Creating repository for offline building with
dependency:go-offline fails
Posted by napple fabble <jm...@gmail.com>.
Tested a little further. I
1. cleared my local repository
2. did mvn package
3. did mvn dependency:go-offline
4. went offline
5. moved my local repo to elsewhere (c:\repo\offline-repo-5). My local repo
is completely empty now
6. added "repository" and "pluginRepository" configuration to my pom.xml,
pointing to the previously created offline repo folder:
<repositories>
<repository>
<releases />
<id>offline-repository</id>
<name>local offline build libs</name>
<url>file:///c:/repo/offline-repo-5/</url>
</repository>
</repositories>
- build works now. So based on this I would disagree on the "metadata is
different" reason preventing from using this approach.
The problem is that dependency:go-offline is pretty much useless. If you now
do mvn clean for example, the clean plugin is not loaded and build fails.
You would need to execute at least mvn clean, mvn package, maybe mvn deploy
(even more? cannot say...) lifecycles to ensure all the needed plugins for
offline building are available. dependency:go-offline does not help you with
those at all. I again don't see the point of dependency:go-offline. You
cannot trust it to get your needed plugin dependencies, you can (and need
to) do what it is trying to do by executing mvn clean, mvn package...
manually before going offline, so what does it accomplish? Why not just do
mvn package before going offline?

OK, I'm starting to get it. And you cannot a copy of your local repository as
a "remote repository" by defining it with <repositories><repository> since
the metadata is different?
I could still take the copy of local repository and just copy it to the
place where local repository should be in the offline computer, and it
should work, no?
It just fails because dependency:go.offline has a bug and does not fully do
what you described. It misses maven-surefire-plugin. I guess most won't
notice this since they already have the surefire plugin in their local
repository before dependecy:go-offline.

I am sure you know your stuff, but this does not make sense to me. Why does
dependency:go-offline exist if you cannot use it for this purpose? Isn't it
there to make offline builds possible? What is it used for if it does not
work in this scenario?
