The workaround for OutOfMemory using the ANT compilation hint under Eclipse _java

My reason for this error is that because Ant is executing, the default to the JVM is not enough memory, the need to set the boot parameters to increase the amount of memory allowed to use. If you are executing ant directly from the command line, you can modify the startup command directly. However, executing on Eclipse, the command line setting is not good.
I tried it several times and finally got it done.
The way to do this is to set the parameters directly on the eclipse's execution JVM, as follows:
1. Open window->preferences->java->installed JREs
2. Select the default (in-use) JDK
3. Click Edit. and add the appropriate parameters to the default VM arguments, for example:-xmx1024m
