I'm making a change to a set of code for a Flex project that I didn't write and was set up to compile using ant tasks. I assume that the codebase was stable at the last checkin but I'm running into memory issues when trying to build a project using MXMLC and ant (see stack trace below). Before, I was just getting an out of memory error. I tried using a different machine and got this more verbose exception (including problems with the image fetcher). I've tried using various versions of the SDK, I've tried replacing the <mxmlc> tag with <exec executable="mxmlc"> with no luck. Here is my java version in case that has anything to do with it:

» java -version
java version "1.6.0_20"
Java(TM) SE Runtime Environment (build 1.6.0_20-b02-279-10M3065)
Java HotSpot(TM) 64-Bit Server VM (build 16.3-b01-279, mixed mode)

Any help would be appreciated. Thanks!

给 Java-VM 更多的堆空间，例如

java -Xmx1024M

或任何你需要的:-)。在 Linux（可能还有其他 Unix）下，可以使用 ant 二进制文件来解决问题：

ANT_OPTS="-Xmx1024M" ant

我们使用 ant 在单个机器上构建一个 flex 应用程序（没有 flex builder），解决堆空间错误的唯一方法是增加 build.xml 中的 maxmemory。

设置 ant_opts 和 java config 对我们不起作用。

<mxmlc file="${src-cp}/CP_main.mxml" output="${bin-dir}/CP/CP_main.swf" 
    show-unused-type-selector-warnings="false"
    static-link-runtime-shared-libraries="true" fork="true" maxmemory="1024m">

我对compc也有类似的问题。唯一似乎对我有帮助的是设置 fork="true" maxmemory="256m"

如果您从 Flash Builder 中启动 Ant 任务，请转到Default VM ArgumentsPreferences > Java > Installed JREs > Edit下为 Java 添加适当的命令行参数，例如-Xmx4096M

在我的情况下，当我添加第 5 个 SWF 时，我正在编译几个不同的 SWF，即出现内存错误。我解决它的方法是稍微破解一下。我使用 exec ant 任务为正在编译的每个 swf 生成了新的 JVM。

<target name="main">
            <exec executable="ant" os="Mac OS X">
                <arg value="antTargetCompileSwf1"/>
            </exec>
            <exec executable="ant" os="Windows 2000,Windows NT,Windows XP,Windows 8">
                <arg value="antTargetCompileSwf1"/>
            </exec>
            <exec executable="ant" os="Mac OS X">
                <arg value="antTargetCompileSwf2"/>
            </exec>
            <exec executable="ant" os="Windows 2000,Windows NT,Windows XP,Windows 8">
                <arg value="antTargetCompileSwf2"/>
            </exec>
        </target>

这是一个示例，其中我在同一构建文件中引用每个目标 antTargetCompileSwf2，该构建文件将包含最初引发内存错误的 mxmlc 任务
