You can solve it with a variable "base_executed", the first time that
base task is executed this variable is set as true, the next time the
base task should be by passed.
Example:
task :base do
next if :base_executed
puts "BASE"
set :base_executed, true
end
task :recipe_one do
puts "ONE"
end
task :recipe_two do
puts "TWO"
end
task :combined_recipe do
puts "COMBINED"
end
Good night!
