apache-flex - Flex 4 应用空白

Question

我正在构建一个 Flex 4 应用程序(使用 flexmojos 而不是 FlexBuilder)。如果我使用 mx:Application 如下创建测试应用程序，那么我会看到一个按钮，正如我所期望的那样:

<mx:Application
    xmlns:s="library://ns.adobe.com/flex/spark"
    xmlns:mx="http://www.adobe.com/2006/mxml">

    <s:Button
        label="Button"/>

</mx:Application>

但是，如果我使用 s:Application，那么我看到的只是一个空白(白色)屏幕:

<s:Application
    xmlns:s="library://ns.adobe.com/flex/spark"
    xmlns:mx="http://www.adobe.com/2006/mxml">

    <s:Button
        label="Button"/>

</s:Application>

顺便说一句，我目前没有使用 html 包装器，我只是直接在浏览器中加载 swf。

这是我的pom...

有人知道我做错了什么吗？谢谢

更新:

我现在将所有 RLS 作为 .swz 文件存储在与 .swf 文件相同的位置，并且我将 RSL URL 设置如下:

                            <configuration>
                    <policyFileUrls>
                        <url>http://fpdownload.adobe.com/pub/swz/crossdomain.xml</url>
                    </policyFileUrls>
                    <rslUrls>
                        <url>{artifactId}_${flex.sdk.version}.{extension}</url>
                    <url>http://fpdownload.adobe.com/pub/{extension}/flex/${flex.sdk.version}/{artifactId}_${flex.sdk.version}.{extension}</url>
                    </rslUrls>
                </configuration>

不过，该应用程序仍然是空白的。使用 FireBug，我看不到任何对 RSL 的请求，也没有任何与此相关的错误消息。似乎甚至没有尝试加载 RSL。

这很奇怪!

如果您使用的是 mojos < 4，请将此添加到您的 flexmojos-maven-plugin 配置中

<configuration>
    <configurationReport>true</configurationReport>
    <sourceFile>Main.mxml</sourceFile>
    <configFiles><!-- Fix for Mojos's < 4 -->
        <configFile>flex-config-swf-version-11.xml</configFile> 
    </configFiles> 
...

然后创建这个文件

<?xml version="1.0"?> 
<flex-config> 
        <swf-version>11</swf-version> 
</flex-config>

如果你是 4+，你可以将它添加到你的配置中

<configuration>
    <configurationReport>true</configurationReport>
    <sourceFile>Main.mxml</sourceFile>
    <swfVersion>11</swfVersion>
...
