的Flex Ant任務問題

當我嘗試構建一個使用Flex的項目，並且其中的Flex SDK是一個驅動器和項目文件上，我都會在螞蟻以下錯誤：的Flex Ant任務問題

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

這似乎是Flex mxmlc ant任務的問題。任何人都知道這個的根本原因？它的工作原理，如果我移動的Flex SDK到項目文件夾，但我不喜歡被hackish的那樣......

螞蟻在詳細模式下得到：

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

看起來'FlexTask.java' Flex ant任務的'private void executeOutOfProcess（）'方法存在一個錯誤。它似乎使用對一個文件的引用來獲取絕對路徑，然後使用該路徑訪問其他內容。我真的不想再花更多時間在它上面，所以就此離開。 – nash 2009-11-05 23:21:40

我確定這實際上是flex ant任務中的一個錯誤。 FlexTask.java沒有正確的路徑在Windows機器上的多個驅動器上工作。

你有沒有把flexTasks.jar到lib文件夾你的螞蟻安裝？

在我來說，我已經複製到D:\Flex_sdk_3.3.0\ant\lib\flexTasks.jarD:\apache-ant-1.7.1\lib\

這不是問題，因爲如果我將SDK移動到其他驅動器，則構建工作。不過謝謝。 – nash 2009-11-05 19:03:26

某處有是沒有在它前面的驅動器盤符的路徑。所以當你在'正確'的驅動器上時，它會工作，但不是。

我找到this博客文章 - 在文中搜索MXMLC= - 有人發現了一個解決方案，用於引發相同異常的Mac安裝。你可能能夠適應你的情況。（看起來可能是在安裝並配置flex mxmlc編譯器時，它並不一定在需要的地方包含驅動器號。）

而不是移動或複製jar，也許您可以將完整路徑添加到它將字母作爲構建中的屬性，然後將其附加到類路徑中。

將Flex sdk/x.x文件夾複製到與您的源相同的驅動器中，調整flex.sdk.home ant變量並重建。
