How can I execute multiple tasks in one command?

Answer 1

Yes, it is possible to execute multiple leiningen tasks in sequence with one command.

Example:

lein do clean, test

Answer 2

You can't do it at the command line directly, but you can with an alias in your project.clj file:

:aliases
{"go" ["do" "clean," "jar"]}

So at the command line you would then be able to:

lein go

(The comma after clean is needed, because lein do expects a comma after each command in order to allow passing arguments to the commands.)
