Sencha Cmd无法解析依赖PARRENTCLASS

Question

我遇到Sencha Cmd工具的问题;当我尝试构建我的应用程序时，我收到此错误：

[DBG] adding implicit dependency for Ext.application call
[DBG] Creating virtual class definition Myapp.app.Application
[DBG] detected application name : Myapp
[DBG] Caching symbol declarations
[DBG] Linking class inheritance graph
[ERR] Failed to resolve dependency PARRENTCLASS for file Myapp.
[ERR] Error executing page compilation Unknown definition for dependency : PARRENTCLASS

有谁知道这意味着什么？ PARRENTCLASS依赖项和文件名Myapp看起来很奇怪，因为我甚至没有该文件。

我的app.js：

// DO NOT DELETE - this directive is required for Sencha Cmd packages to work. 
//@require @packageOverrides
Ext.application({
    name: 'Myapp',
    appFolder: 'app',
    autoCreateViewport: true,
    controllers: ["BreadCrumbs", "Content", "Lang", "Login", "Ping", "SidebarMenu", "TopMenu"],
    requires: ['Myapp.singleton.Context', 'Myapp.singleton.StoreRefresh', 'Myapp.singleton.Utils', 'Myapp.singleton.MsgBox']
});

导致此错误的原因是什么？
