灵活蚂蚁任务问题

build ant flex

nash · 技术社区 · 15 年前

当我尝试构建一个使用flex的项目时,如果flex sdk在一个驱动器上,而项目文件在另一个驱动器上,那么在Ant中会出现以下错误:

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

这似乎是flex mxmlc ant任务的问题。有人知道这一切的根本原因吗?如果我把flex-sdk移到项目文件夹中,它会起作用,但我不喜欢被这样的黑客攻击…

蚂蚁在详细模式下给出:

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
    [mxmlc] Exception in thread "main" 
  [antcall] Exiting E:\svn\trunk\dev\modules\web\webapps\lpjserver\lpjserver-build.xml.

你放了吗? flexTasks.jar 进入之内 lib 您的Ant安装文件夹?

在我的情况下,我复制了 D:\Flex_sdk_3.3.0\ant\lib\flexTasks.jar 进入之内 D:\apache-ant-1.7.1\lib\

我确定这实际上是flex ant任务中的一个bug。flextask.java没有在Windows计算机上跨多个驱动器执行正确的路径。

martin clayton egrunin 14 年前

在某个地方,有一条路径前面没有驱动器号。所以,当你在“正确”的驱动器上时,它会工作,但不可能。

我发现 this 博客文章-搜索 MXMLC= 在文本中-有人找到了一个针对Mac安装的解决方案,引发了相同的异常。你也许能够适应这种情况。(可能在安装和配置flex-mxmlc编译器时,不必在任何需要的地方都包含驱动器号。)

与其移动或复制JAR,也许您可以在构建中将驱动器号作为属性添加到它的完整路径中,然后将其附加到类路径中。

将flex sdk/x.x文件夹复制到与源文件相同的驱动器上,调整flex.sdk.home ant变量并重新生成。
