构建Flex的奇怪问题(在正确的代码上出现无关的错误)

问题

我的构建有问题.当我向代码添加一个有效的语句时,它将不再编译,并且它会因无关文件的错误而失败.我在命令行中遇到了使用ant构建或使用mxmlc构建这些问题.

将有效语句添加到myLittleBox.mxml将导致此错误.注意：

>所有错误都在ViewerMain.mxml中.此文件不是主mxml文件,但它是从主mxml文件引用的.
>在更改myLittleBox.mxml之前,ViewerMain.mxml没有编译错误
>没有与myLittleBox.mxml相关的错误
> myLittleBox.mxml没有对ViewerMain的引用,只使用spark组件
> ViewerMain.mxml没有对myLittleBox.mxml的直接引用.它的孩子的孩子的孩子会引用myLittleBox.mxml
>添加到myLittleBox.mxml的有效语句可能有很多内容(它们都会破坏它们),包括注释.

题

什么可能导致这些错误？我该如何解决这些问题？非常感谢提示或一点点洞察力.

观察(选修)

评论似乎没有打破构建,因为如果我放一个较短的注释没有编译错误.例如,如果我将以上评论替换为此评论：

/*
            This 
            is 
            going
            to 
            break
            it.
        */

构建不会破坏.类似地,如果我添加一个延伸超过4-5行的ArrayCollection定义,构建将会中断.但如果定义仅在1-2行上进行,则构建不会中断.

临时解决方案(按要求)

我的项目看起来像这样：

Model
     /        
Viewer 1    Viewer 2

我有两个观众正在偏离同一个模型.它们都具有对模型的引用,但它们没有对彼此的引用,并且模型没有对任一查看器的引用.

> ViewerMain.mxml文件位于Viewer 1中.
> myLittleBox.mxml文件位于Viewer 2中.

我注意到Model在Viewer 1中使用了一个常量.这导致在构建Viewer 2时构建了所有Viewer 1.我将常量从查看器1移动到模型(无论如何它应该在那里)并且我的项目成功构建,因为查看器1和查看器2没有同时构建.

这有助于解决问题,但这只是解决问题的症状.我仍然非常好奇当我向myLittleBox.mxml添加注释时,导致编译器在ViewerMain.mxml上失败的原因.我想现在仍然是个谜.
