Sencha Cmd Error: Build Failed

Question

After running sencha generated app Practise '../www/Practise' it showed some errors. Here the error message:

[ERR] BUILD FAILED
[ERR] java.lang.NullPointerException
[ERR] 
[ERR] Total time :4 seconds
[ERR] com.sencha.exceptions.BasicException

Answer 1

I dont know if this is the same issue you were having but this is why I got that error:

1. I tried to generate the app unsuccessfully
   • This created a directory for my app and put some files in it but the app was incomplete
2. I fixed the original issue and ran the command again.
   • I got the error you were receiving.

This was because the folder in www/ yourproject already existed. I deleted this folder and ran the command successfully.

Hope this helps!!
