ignore in app.json does not ignore files

[Kurt001]

Hi,
I am trying to ignore files and folder, but it seems not to work.
I am running the command:
sencha app build package

App.js

"extras": [
        "resources/fonts",
        "resources/images",
        "resources/css"
    ],

"ignore": [
        "104_imge\@2x\.png", //file example
        "resources/images/hdmi$" /folder example
    ],

the file name is:
resources/images/104_imge@2x.png

The folder exists twice, but only one should be excluded. The other is in a subfolder of images.
If I add hdmi$ both folder are ignored.

Any idea how to ignore single files by name and how to ignore folders at a certain position?

    "ignore": [
        "\.svn$",
        "resources/images/ignore"
    ],

I created a new dir in resources/images/ and the above ignored that ignore dir for me
