Thank you for your help and persistence!

Oops. Thanks. I guess our Jenkins scripts "fix" that one.

I think that comes from the branch name, which dictates the URL of the zip file downloaded.
It used to be hard coded to master, but got updated to support stable/*

Yes, it would be nice to add these. Not tried a setup in the presence of a proxy.

I think you can setup a proxy ignore list:
It's a hack, but you could write the appropriate config file at this point:

I think this will be fixed by (3). I guess the following line (silently!) fails due to your proxy issues:

Thanks, I somehow missed out that bit! I have added that to the wiki.

Thanks, added something that should help. I was testing on Windows.

I would certainly welcome your patches :-)
I hope the suggestions above might help anyone who gets chance to take a look.

Thank you! Sorry there was so much pain getting it all working!
