Running from within a firewall

[jlpoolen]

This is really a maven issue; however, others may be in the same position I find myself and addressing this issue could prove helpful.

I was able to successfully run the cleo-primer from behind a less-restrictive firewall; the remote fetching worked and the server started. Now I am trying to run the sample from behind a restrictive firewall and the startup fails because remote files cannot be downloaded.

I checked Maven's site http://maven.apache.org/guides/mini/guide-proxies.html and duly created a file ~jlpoole/.m2/repository/settings.xml as follows:

jlpoole@themis /usr/local/src/cleo-primer $ cat ~/.m2/repository/settings.xml
--settings--
--proxies--
--proxy--
--active--true--/active--
--protocol>http--/protocol--
--host--[the proxy server]--/host--
--port--[the proxy port]--/port--
--/proxy--
--/proxies--
--/settings--

Note: I had to substitute "--" for opening and closing markup since my pasting them in caused them to disappear.
jlpoole@themis /usr/local/src/cleo-primer $

Yet, when I try to run the launching command, it's showing the proxy is not working:

    jlpoole@themis /usr/local/src/cleo-primer $ MAVEN_OPTS="-Xms1g -Xmx1g" mvn jetty:run -Dcleo.instance.name=Company -Dcleo.instance.type=cleo.primer.GenericTypeaheadInstance -Dcleo.instance.conf=src/main/resources/config/generic-typeahead

Is there something that can be tweaked to bypass refreshing from remote sources so when the example is run from within a restrictive firewall it is ready to run and/or aborts trying to get the latest files? Or have I missed some basic Maven configuration making my attempt to create a proxy entry useless?

[jlpoolen]

When I first installed the cleo-primer, I did so as root and with a not-as-restrictive firewall. The appropriate files were downloaded by maven and stored under root's .m2/repository. When I was under a restrictive firewall, I attempted to run as user jlpoole and since it was the first time, the failed attempt to download through the proxy proved fatal to the launching of the server. When I changed to root and ran the cleo-primer, attempts were made to download, again, but since the previous run in the less restrictive environment had successfully downloaded the requisite files, the files were available for this session where the Maven proxy configuration does not seem to be working.

Conclusion, once you're able to download the required files, they can be used later when download is not possible. The project uses cached files.

It is not necessary to install cleo-primer as root. It can be any user like jlpoolen under a restrictive firewall. For the maven repository/cache, once you have needed jars downloaded, they are cached and reused.
