Deciphering Sencha Cmd errors

Hi,

When I am building my project, I get the follwoing error.

Code:

[INF] Concatenating output to file C:\dev\BOXIT-Project\Boxit\BoxIT/build/temp/p
roduction/BoxIt/sencha-compiler/cmd-packages.js
[INF] Adding external reference : @full-page => @overrides

tion\BoxIt\sencha-compiler\cmd-packages.js

xit\BoxIT/build/temp/production/BoxIt/sencha-compiler/cmd-packages.js
[INF]
[INF] -refresh-app:

C:\dev\BOXIT-Project\Boxit\BoxIT\.sencha\app\refresh-impl.xml:44: com.sencha.exc
eptions.ExBuild: java.lang.IllegalArgumentException: 0 > -1

When I look into the two XML files that Cmd says have the errors it does not make me any wiser.

Anybody who can point me in some ind of direction where to look for a solution to this?
