Re: "curl: (7) couldn't connect to host error" in Execute shell build step

Ah, that was the problem! Thanks! Most of my environment variables were 
missing when non-interactive shells ran.

The environment will be different. The first thing I'd suspect is the
need for a proxy to connect to GitHub. Are there environment variables
like http_proxy or HTTP_PROXY when you run commands interactively? Is
the host behind some corporate firewall that prevents direct HTTPS
connections?

Yes. I'm using my local machine as a slave, and everything in my script 
works when I run it myself.

I see! Thanks for the info - that makes more sense now.

So you were able to run "

curl 
https://raw.github.com/appium/appium/master/sample-code/examples/node/simplest.js";
 interactively on the same host?

Exactly which scripts are executed on startup depends on the shell and the 
options it was invoked with.  As you can see, Jenkins is invoking "/bin/sh 
-xe". You should check whether /bin/sh is Bash or something else. If it is 
Bash, consult the manual to see exactly what those options mean and what 
happens at startup:

http://www.gnu.org/software/bash/manual/bashref.html#The-Set-Builtin>
http://www.gnu.org/software/bash/manual/bashref.html#Bash-Startup-Files>

If it is Bash, no startup files are read because it is executed as the name 
"sh" non-interactively. This is a good thing because it makes it easier to 
control the environment separately from interactive logins. I use a script 
just for setting build-related environment variables which I source within 
the scripts in Jenkins jobs rather than ~/.bash_profile.
