Apache flex Ant和Flex-4问题，找不到MXMLC.jar！

我将flex应用程序从flex 3.5更新为flex 4.0。 我们正在使用ant编译我们的项目，我们有一个mxmlc任务来处理flex部分。 升级后，我们的mxmlc任务中断

以下是任务定义：

<taskdef resource="flexTasks.tasks">
        <classpath>
            <pathelement path="${FLEX_HOME}/ant/lib/flexTasks.jar"/>
            <fileset dir="${FLEX_HOME}/lib">
                <include name="**/*.jar"/>
            </fileset>
        </classpath> </taskdef>

我检查了${FLEX_HOME}/lib文件夹，可以在那里看到mxmlc.jar文件

以下是ant的详细输出：

我感谢你对解决这件事的评论

谢谢，

-升级到ant 1.8解决了这个问题

---

编辑：Ant 1.8.1也有同样的问题，但在Ant 1.8.2中已修复。

我将此问题追溯到Adobe SDK zip文件，将解压内容保留在不允许我的hudson用户阅读内容的权限下。一旦我对安装的FLEX_HOME中的文件和目录做了一些chmods，一切都很好。

朋友

请从{FLEX HOME}\ant\lib目录复制最新的flexTask.jar文件并粘贴到ant\lib中

拉吉。

我也有这个问题。我发现$ANT_HOME/lib目录中有一个旧的flexTasks.jar。当我删除这个文件时，问题中的ANT配置对我有效。

我也有同样的问题，因为运行ANT的用户没有读取Flex sdk目录的权限。

有完全相同的问题，但ANT版本已经是1.8，chmod 777所有sdk文件，仍然不工作，知道吗？谢谢在代码建议中添加解释会使其更加有用。您应该稍微解释一下您的答案。
