Estou usando a soluçãoaquipara suporte a scala, mas isso não colore adequadamente o código scala e gera vários erros ao processar lstset - % ! Package keyval Error: breakatwhitespace undefined.Alguém pode me ajudar a descobrir o que há de errado com este exemplo simples?
\documentclass[journal]{IEEEtran}
\usepackage{listings}

frame=single,
breaklines=true,
breakatwhitespace=true
tabsize=3
}
% A number of keyval errors occur here - basically
% nothing in lstset is recognized. Errors look like:
% ! Package keyval Error: breakatwhitespace undefined.

Conforme observado por Peter em seus comentários, sua distribuição TeX parece muito desatualizada. É hora de tirar a ferrugem e iniciar seu gerenciador de pacotes.
Além disso, está faltando uma vírgula depois de breakatwhitespace=true.
Além disso, desde outubro de 2013, o listingspacote vem com uma definição de linguagem para Scala (no formatolstdvrs.dtxarquivo). Se você atualizar sua distribuição TeX, não deverá ser necessário redefinir esse idioma do zero em seu .texarquivo para usá-lo.
