How to use the 'overrides' folder generated by Sencha cmd for an Ext JS 4 project

问题

I have generated a project using Sencha cmd. This creates a nice folder named 'overrides' where I have put my overridden Ext.Ajax class. I then include it in my app.js file like so

requires: [
    'overrides.Ajax'
]

This works just fine when using my app, however when I try to build it using Sencha cmd I get the following error:

[ERR] BUILD FAILED
[ERR] com.sencha.exceptions.BasicException: The following error occurred while e
xecuting this line:
[ERR] Z:\public_html\LoginScreen\.sencha\app\build-impl.xml:469: com.sencha.exce
ptions.ExBuild: com.sencha.exceptions.ExBuild: Failed to find any files for Z:\p
ublic_html\LoginScreen\app\app.js::ClassRequire::overrides.Ajax

Does anyone know how to properly include files that are inside the overrides folder?

回答1:

Turns out I needed to edit the .sencha/app/sencha.cfg file, adding the following to the end of the app.classpath

,${app.dir}/overrides

For Ext 5 user, you can specify "overrides folder" in app.json. Example:

"overrides": "${app.dir}/overrides",

You probably need path defined in your loader config for overrides.

Something like this:

Ext.Loader.setConfig({
    paths: {
        'Ext.ux': 'js/extjs/ux',
        'overrides' : 'somepath/to/overrides',
        'Skirtle.CTemplate':'js/extjs/ux/SkirtleCTemplate.js' //<-- specific component
    }
});

For me just the

requires: [
    'overrides.Ajax'
]

didn't work I had to add

requires: [
    'MyApp.overrides.Ajax'
]

And it worked :)

Also the vars

// @require @packageOverrides
// @require @appOverrides

don't do anything for me, so the steps are

add the ,${app.dir}/overrides in the sencha.cfg
add the requires in the app.js inside the Ext.application

Tested in Sencha Cmd v4.0.2.67
