Sweet fancy pajamas it works. After a lot of frustrating fiddling, and for reasons I don't entirely understand, in order to invoke the build process from a batch file, the batch file must contain the word build in its title, and need only contain the command "ant" (the environmental variables must be set, of course). My first test had worked, and then it wouldn't after I changed the name of the batch file, and I thought the issue was some syntax inside of the batch file or some auto-changed environmental variable. End solution is pretty simple, though, at least on this computer. Will try on my home computer tonight.
