Since Eclipse is a Java program, you can increase the heap size of Eclipse by using JVM memory options -Xms and -Xmx. There are two ways to provide JVM options to eclipse either updating the Eclipse shortcut or adding -vmargs on eclipse. ini file.
-- Go to the Eclipse Window > preferences, in "Java > Installed JREs". -- Copy the current default JRE with a new name, for example myJRE. -- Select the new JRE and click on the "Edit" button. -- In the "Edit JRE" dialog, add your JVM arguments in the "Default VM Arguments" field.
In the left pane of Run Configurations window, navigate to the Java Application node and select the Java application for which you need to increase the heap size. Then in the right pane, click on the Arguments tab. -Xmx[CUSTOM_SIZE] – This means that your JVM will be able to use a maximum of Xmx amount of memory.
You can set the VM arguments for a specific run configuration:
Run → Run Configurations... → Arguments Tab → VM arguments
Btw, you may want to try -Xms instead of -Xmms.
