Ant: Setting Your JVM Memory Options (-Xms -Xmx, etc.) 0

Ant provides an option to allow you to set your default JVM memory options globally.  On Windows, you must create a bat file titled antrc_pre.bat under your %USERPROFILE% directory.  Ant will read in this file to set the ANT_OPTS values before executing your build file.  Here is the contents of my antrc_pre.bat:

set ANT_OPTS=-Xms512m -Xmx1024m
