unexpected behaviour: gulp watch and gulp build at the same time

[gruppjo]

Sometimes when running gulp watch and gulp build at the same time the app/main/constants/config-const.js is emptied.

[RomainGoncalves]

Ahhh is that why?! I was wondering why my const file was empty when I was running gulp build!
And then no matter if you try to run either command alone, the file stays empty...

[MathiasTim]

yeah, thats why. Unfortunately we cannot reproduce this issue continuously. Can you? Thanks for your help!

today I encountered these errors in addition to config-const.js being emptied:

[18:13:05] 'clean' errored after 1.76 s
[18:13:05] Error: ENOTEMPTY: directory not empty, rmdir '/Users/jonathan/Projects/m-way/qr-code-test/.tmp/main/styles'
    at Error (native)

I suspect this is because build is trying to empty a directory watch is still working on.

[18:07:28] 'build-templates' errored after 1.87 s
[18:07:28] Error: EEXIST: file already exists, mkdir '/Users/jonathan/Projects/m-way/qr-code-test/www/main/templates'

No Idea why these might occur. But I suspect the same origin as the first one. Working on the same files concurrently.

They're quite reproducible with the following setup

$ node -v
v4.2.1
$ npm -v
2.14.7

Maybe I can do some more research if others have this problem as well under new node versions and gulp running concurrent tasks in different processes.

[MathiasTim]

+1 having this issue from time to time.

[gauravarora]

I have this problem too with the following versions

bash-3.2$ node -v
v4.2.1
bash-3.2$ npm -v
3.3.12

+1

Is there a way to "refill" the file?

Now I'm getting Uncaught Error: [$injector:unpr] Unknown provider: ConfigProvider <- Config ...

[gruppjo]

We usually just use git and simply checkout the file.
git checkout app/main/constants/config-const.js

you can generate a new file with the sub-generator:
yo m-ionic:constant config --template=config

Closing this one. Discussion moved the new collective ticket: #453
