Difference between `warble executable war` vs `bundle exec warble executable war`

I am trying to package a Rails application to a WAR file. I am pre-compiling the assets, then using warbler to package the application to a WAR file.

Pre-compile:

bundle exec rake assets:precompile

Now im trying to package the Rails application to a WAR file using the command:

warble executable war

What is the main difference between the above command and the below command:

bundle exec warble executable war
Solution 
  • bundle exec warble executable war

    bundle exec will make sure it is using the gem version mentioned in Gemfile
