A broken pipe inside of the Closure Compiler often means that your JavaScript has a syntax error.

agibralter commented 13 years ago

I'd watch out for JS keywords like char and float being used as variable names and object keys -- that always gets me. e.g. $("#foo").css({float: "left"}) will often cause JS minifiers like YUI to fail.

masterkain commented 13 years ago

I was suspecting that jammit wasn't the culprit here.

However we are upgrading our app to rails 3.1 and the same js/css gets minified well in rails 2.3 + jammit.

I'll take a second look, too bad the stack trace does not indicate what's failing; maybe this version of the closure gem got more strict.
