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
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
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
set defaultXmx=-Xmx1024M
原因就是此处设置的Xmx为1024M，编译打包APK时java虚拟机内存空间不足，修改为512M即可正常编译打包了。
set defaultXmx=-Xmx1024M
