的Flex Ant任务问题

当我尝试构建一个使用Flex的项目，并且其中的Flex SDK是一个驱动器和项目文件上，我都会在蚂蚁以下错误：的Flex Ant任务问题

[mxmlc] java.lang.NoClassDefFoundError: flex2/tools/Compiler 
[mxmlc] Exception in thread "main"

这似乎是Flex mxmlc ant任务的问题。任何人都知道这个的根本原因？它的工作原理，如果我移动的Flex SDK到项目文件夹，但我不喜欢被hackish的那样......

蚂蚁在详细模式下得到：

compile.main: 
dropping E:\c from path as it doesn't exist 
dropping E:\programs\flex-sdk\lib\mxmlc.jar from path as it doesn't exist 
    [mxmlc] java.lang.NoClassDefFoundError: flex2/tools/Compiler

看起来'FlexTask.java' Flex ant任务的'private void executeOutOfProcess（）'方法存在一个错误。它似乎使用对一个文件的引用来获取绝对路径，然后使用该路径访问其他内容。我真的不想再花更多时间在它上面，所以就此离开。 – nash 2009-11-05 23:21:40

我确定这实际上是flex ant任务中的一个错误。 FlexTask.java没有正确的路径在Windows机器上的多个驱动器上工作。

你有没有把flexTasks.jar到lib文件夹你的蚂蚁安装？

在我来说，我已经复制到D:\Flex_sdk_3.3.0\ant\lib\flexTasks.jarD:\apache-ant-1.7.1\lib\

这不是问题，因为如果我将SDK移动到其他驱动器，则构建工作。不过谢谢。 – nash 2009-11-05 19:03:26

某处有是没有在它前面的驱动器盘符的路径。所以当你在'正确'的驱动器上时，它会工作，但不是。

我找到this博客文章 - 在文中搜索MXMLC= - 有人发现了一个解决方案，用于引发相同异常的Mac安装。你可能能够适应你的情况。（看起来可能是在安装并配置flex mxmlc编译器时，它并不一定在需要的地方包含驱动器号。）

而不是移动或复制jar，也许您可以将完整路径添加到它将字母作为构建中的属性，然后将其附加到类路径中。

将Flex sdk/x.x文件夹复制到与您的源相同的驱动器中，调整flex.sdk.home ant变量并重建。
