Build task "gulp build-electron" fails on "manifest.name"

[FlipOneDev]

Either document that "gulp build-electron" must first be preceded by "gulp build" or integrate the "build" task into the "build-electron" task.

you should replace

manifest = appDir.read('./package.json', 'json');

by

manifest = projectDir.read('./package.json', 'json');
