Answer 1

You can properly set the -Xms512m -Xmx1024m options to the Ant bin/sh script that Eclipse will run once you launch a build.

1. Go to your Eclipse folder
2. Go to plugins > org.apache.ant_ > bin

3. Modify the OS related Ant file

   • For Windows: Add this line to the ant.bat file export ANT_OPTS=-Xmx512m

   • For Unix/Mac OS X: You can directly edit the ant_exec_command command at the end of the ant file or setting the $ANT_ARGS variable
