Proxy support not working if using the environment

[ph]

I am currently looking to add the proxy support back into logstash 1.5, but I am unable to make the jars download uses a proxy. I was expecting setting the http_proxy env variable to an appropriate proxy and the libs management would pick it up.

Versions:

• jar-dependencies 0.1.7
• ruby-maven 3.1.1.0.8

Scenarios

1. I've looked a bit at the codebase of both rubygems and jar-dependencies, the current implementation of jar-dependencies uses the Gem.configuration[:proxy] but in the rubygems test suite they uses Gem.configuration[:http_proxy]. After making my code update both the http_proxy and the proxy key and adding trace I see that my configuration is correctly send to the mvn class loader (in ruby maven)
   but the jar download isn't using the proxy.
2. If I create a a simple settings.xml and set the JARS_MAVEN_SETTINGS to use it, it doesn't go to the proxy..
3. If I move the same settings.xml file in the ~/.m2 directory, the jars download will go through the proxy

Settings.xml

<settings>
  <proxies>
   <proxy>
      <id>example-proxy</id>
      <active>true</active>
      <protocol>http</protocol>
      <host>127.0.0.1</host>
      <port>3128</port>
    </proxy>
  </proxies>
</settings>

fixed the maven-settings issue.

the proxy support from Gem.configuration is still pending - not sure yet how to fix it

@mkristian This is still an issue today (jar dependencies 0.3.5), I've run into it and I have a setup to reproduce it. Do you want to reopen it or create a new one?

I am using a 2 vagrant VM, one with squid3 and the other vm only has access to the squid proxy.
When I create the settings.xml it fixes the problem.

#/etc/squid3/squid.conf
#Recommended minimum configuration:
acl localhost src 127.0.0.1/32
acl to_localhost dst 127.0.0.0/8
acl localnet src 0.0.0.0/8 192.168.100.0/24 192.168.1.0/24
acl SSL_ports port 443
acl Safe_ports port 80      # http
acl Safe_ports port 21      # ftp
acl Safe_ports port 443     # https
acl Safe_ports port 70      # gopher
acl Safe_ports port 210     # wais

acl Safe_ports port 488     # gss-http

@ph will look into this asap

@mkristian any ETA on when we can expect a new version with #16? Thanks much for the fix.

[mkristian]

@suyograo getting the tests green on the weekend and then I release it and update jruby to bundle the new release

@mkristian we included 0.3.7 in Logstash 5.1.1, and a user is reporting what looks like a bug in jar_dependencies. See elastic/logstash#6396 for details.
