Gradle打包的时候经常出现此错误，命令--stacktrace

Error occurred during initialization of VM
Could not reserve enough space for object heap

目前google and 百度查询有两种解决方案

1.设置java的

-Xms128m
-Xmx512m
-XX:MaxPermSize=250m

修改这三个参数

2.升级JDK

经过测试2种方案都不行

通过

dx.bat --dex

命令的dx.bat脚本有这样一句代码

REM By default, give dx a max heap size of 1 gig and a stack size of 1meg.
rem This can be overridden by using "-JXmx..." and "-JXss..." options below.
set defaultXmx=-Xmx1024M
set defaultXss=-Xss1m
