I'm trying to build extjs5 application with Cmd v5.0.0.160.
I have ruby2.0 installed and sencha cmd on my PATH var.
Here is the error that I get when running sencha app build:
...
[INF] Capturing theme image

The application is working OK in development mode (sencha app watch).
Since it looks like it's about themes, I'm not using custom theme but ext-theme-neptune.
Does anybody have a clue what is it about? I will appreciate any idea!
Solution:
The debug mode showed that the problem was in missing directory Cmd/5.0.0.160/bin/linux-x64. However there was Cmd/5.0.0.160/bin/linux dir, therefor soft-linking linux to linux-x64 fixed the issue.
It's a really annoying bug in Sencha CMD 5 - they swallow the output of any processes they launch.
Or, more accurately, they route the output to the debug logs. So you can see what's going on if you turn debug logging on. Try sencha -d app build - just be prepared to trawl through a lot of output.
