Is there actually another instance of watch running before you run sencha app watch?

[kousikd]

I'm not sure after running that command for a quite few times, I don't see any process running named - sencha, connect, app, watch, portnumber, etc., Please let me know if you want to see the full logs.

Hi,
The process sometimes takes time to stop ..
I do it this way for myself:
me@me:~$ ps -ejH | grep sencha
7292 7292 4224 pts/18 00:00:00 sencha
me@me:~$ sudo kill -9 7292

I have this problem. How can I fix this?

My problem was that build directory was lock
