Question

我正在使用ANT构建工具构建我的Android应用程序。

使用dexgaurd在本地计算机上运行时，它可以正常运行。
在不使用dexgaurd时，它在服务器上运行良好。
使用dexgaurd时，它在服务器上失败。

服务器规格：

             total       used       free     shared    buffers     cached

Mem:          7978       7328        649          0         32        391
-/+ buffers/cache:       6904       1073
Swap:         8188        486       7702

以下是错误：

[dexguard] java.lang.OutOfMemoryError: PermGen space

以下是环境变量及其值：ANT_OPTS

[echo] ant build config -Xms1024m -Xmx2048m -XX:PermSize=1024m -XX:MaxPermSize=2048m -XX:+UseConcMarkSweepGC -XX:+CMSPermGenSweepingEnabled -XX:+CMSClassUnloadingEnabled

我已将XX：MaxPermSize更改为4096，但仍然会出现相同的错误。它始终在这一点上失败，无论-Xms -Xmx -XX值是什么。我是否必须为环境添加一些其他值才能使其正常工作。这类问题的一般解决方案是增加-XX中的内存值：MaxPermSize但它没有帮助

更多上下文：ant构建了8个应用程序。构建工作正常，直到第6个应用程序，并且它们都具有类似的custom_rules.xml文件。但它在构建第7个应用程序时失败了。

如果您需要更多信息，请在评论部分提及，我会添加它。我已经搜索了很多关于这个问题并尝试使用解决方案解决它，但从未成功。

如何解决PermGen内存不足错误？
