I have custom tasks in my SBT (0.12.2) project. Let\'s call them a, b and c. So when I\'m in the interactive mode of SBT I can just type <
a
b
c
another way to achieve this is to define an alias in your .sbtrc file which will be in the root of your project directory.
alias all=;a;b;c
you have an additional option of defining these .sbtrc file in your home directory in which case this alias will be available to all your projects.
