java - 在全局范围内限制 Play 框架的 Java 堆空间

Question

我有一个非常旧的 linux 系统并安装了 java 和 play 框架。当我运行 java 时，我得到:

java -version
Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.

所以我在application.conf中限制了java堆空间:

jvm.memory=-Xmx256M -Xms256M

通过该设置，我可以运行游戏测试、游戏运行等......

但我不能跑:

play dependencies 
~        _            _ 
~  _ __ | | __ _ _  _| |
~ | '_ \| |/ _' | || |_|
~ |  __/|_|\____|\__ (_)
~ |_|            |__/   
~
~ play! 1.2.1, http://www.playframework.org
~
Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.

是否有一个全局配置文件或环境变量，我可以在其中限制游戏框架的全局 Java 堆空间？

更新:以下也不起作用:

play dependencies -Xmx256M -Xms256M
~        _            _ 
~  _ __ | | __ _ _  _| |
~ | '_ \| |/ _' | || |_|
~ |  __/|_|\____|\__ (_)
~ |_|            |__/

~ play! 1.2.1, http://www.playframework.org

Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.

Play 似乎没有为依赖项甚至测试命令获取 jvm.memory 设置。强制它使用特定 JVM 设置的一种方法是使用 _JAVA_OPTIONS。

例如:

export _JAVA_OPTIONS="-Xms800m -Xmx1500m -XX:PermSize=64m -XX:MaxPermSize=256m"
play test

或

play deps

你应该看到

~        _            _ 
~  _ __ | | __ _ _  _| |
~ | '_ \| |/ _' | || |_|
~ |  __/|_|\____|\__ (_)
~ |_|            |__/   
~
~ play! 1.2.3, http://www.playframework.org
~ framework ID is test
~
~ Running in test mode
~ Ctrl+C to stop
~ 
Picked up _JAVA_OPTIONS: -Xms800m -Xmx1500m -XX:PermSize=64m -XX:MaxPermSize=256m
Listening for transport dt_socket at address: 8000

请注意，这会将这些设置应用于在设置了 _JAVA_OPTIONS 的终端上运行的所有 java 程序。
