The general solution should be setup a proxy server like nexus, you can access the nexus server in your intranet, and the nexus server can go through your firewall to connect the internet and download artifacts on demand.
Or if you have fuse subscription you can ask for the offline repo we build, which typically resolve the scenario you encounter.
For the offline xsd access issue, the spring should be fine, as we always ship local xsds.
For the blueprint, you MAY encounter an issue which is caused by a known and fixed aries issue, it should be shipped by future FUSE ESB release, if you have fuse subscription you can use that channel to get quick help.
Thanks for the good response.
We're in the process of trying to get a support license, so the fusesource offline repository isn't available to me as an option.
We do have a corporate proxy similar to nexus, but it has a time-limited cache of the artifacts pulled from cached repositories. It is also a dev system here, so isn't considered a mission critical production system.
Rather than set something up that is production worthy, I've gone through the logs of a new installation and extracted all the "Resolving [mvn:..." lines. I massaged that data into a pom of dependencies and used maven to download the artifacts into my local repository. I will then copy that into the fuse local-repo folder.
It is a bit of overkill, since some of those are already in the system/default repository in fuse, and some are plugin and build-related artifacts that maven downloaded but fuse doesn't needed.... but for now it will allow me to push this build into test quickly enough. I'll tailor it down or come up with another solution later.
Basically I've built my own "offline repository" that has all the artifacts I need to run, and then some.
Thanks again for the response.
