Comment 3 for bug 1753340

I'm no Ant expert but it looks to me like the ant plugin is able to pick
up proxy settings from environment variables.

https://github.com/snapcore/snapcraft/blob/master/snapcraft/plugins/ant.py

I don't do python but :

   def get_proxy_options(self, scheme):
         proxy = os.environ.get('{}_proxy'.format(scheme))
         if proxy:
             parsed = urlsplit(proxy)
             if parsed.hostname is not None:
                 yield '-D{}.proxyHost={}'.format(scheme, parsed.hostname)
             if parsed.port is not None:
                 yield '-D{}.proxyPort={}'.format(scheme, parsed.port)
             if parsed.username is not None:
                 yield '-D{}.proxyUser={}'.format(scheme, parsed.username)
             if parsed.password is not None:
                 yield '-D{}.proxyPassword={}'.format(scheme,
parsed.password)

Which I read as looking for environment vars such as:

http(s)_proxyHost

http(s)_proxyPort

http(s)_proxyUser

http(s)_proxyPassword

Ant directly supports an 'autoproxy' option which I've tried (in the
IrrigationForPi app mentioned below)

https://ant.apache.org/manual/proxy.html

Ant also allows you to configure a properties file that contains args
and I think these can be configured to also pickup environment vars.

I believe you can also pass these type of args from the snapcraft ant
plugins ant-options key.

You will see in the IrrigationForPi snapcraft that I've tried this as well.

So I think I just need to know if the build servers provide environment
vars and their names  or what the settings should be.

My script is attached.

I have a second app which is public which has the same problem and which
is on the build servers so you can look at that one.

https://build.snapcraft.io/user/bsutton/IrrigationForPi-Snap

The code is available here:

https://github.com/bsutton/IrrigationForPi

Snapcraft here:

https://github.com/bsutton/IrrigationForPi/tree/master/snap-projects/installer/snap

its the 'tomcat' part that is causing the problem.
