From time to time, when we use ANT script to perform jobs that drag some how longer time. We may encounter Java heap space out of memory error.
The default heap space allocated for Java heap could be 128MB. You may adjust the Java heap size from ANT via environment variable ANT_OPTS:
set ANT_OPTS=–Xmx512m
You may try to set in the system environment variable that is available to all users. If it fail with message “Incompatible minimum and maximum heap sizes specified”, try remove the ANT_OPTS in system environment variable and set it in your home user account.
