Change the default output path not working

[belgoros]

I tried to change the default output path as follows and it didn't work, the add-on put all the stuff into tmp/deploy-dist:

#deploy.js

...
  if (deployTarget === 'development') {
    ENV.build.environment = 'development';
    ENV.build.outputPath = 'dist';
  }
....

What am doing wrong here ? Thank you.
