Disabling some plugins or projects will certainly help to free some memory on Eclipse. If you still see OutOfMemoryError in Eclipse, you probably need to investigate more which plugin/feature or project is creating the problem. Now, the maximum Java heap space for eclipse is set to 512 megabytes. The second way to increase heap size is just to pass the -vmargs directly to the eclipse.exe file if you are starting it from a desktop shortcut or a startup script as shown below:Įclipse -vmargs -Xmx512m The first one is for starting memory and the second argument -Xmx is to maximum memory, you can use suffix k (kilobytes), m (megabytes), and g (gigabytes), but beware of space, otherwise, you will get invalid heap size error when you start the eclipse. If you don't see the -vmargs in your eclipse.ini, just add the following lines and choose how much Java heap space you want for Eclipse: Anyway, it seems time to increase memory a few more MB. Actually, the additional memory might be due to multiple nexus repositories configured on my Maven settings.xml file. You can see I was already running with 512M but even that is not sufficient for Maven :-(. Here is what I had in my eclipse.ini file: You can do it by opening the eclipse.inifile from the eclipse installation folder, next to the eclipse.exe file. Eclipse keeps throwing : Java Heap Space while updating the index or searching for maven artifacts.īefore increasing the heap size of Eclipse, first, check the current memory settings. java heap space" while using Maven in Eclipse. I was getting "an internal error occurred during repository search. I'll tell you the exact steps to increase the java heap space in Eclipse but before that some background on why I had to increase the heap memory of Eclipse. I prefer the second option because it's clean. There are two ways to provide JVM options to eclipse either updating the Eclipse shortcut or adding -vmargs on eclipse.ini file.
Since Eclipse is a Java program, you can increase the heap size of Eclipse by using JVM memory options -Xms and -Xmx. If you are running lots of Java projects in Eclipse and it's throwing OutOfMemoryError every now and then it's time to increase the heap memory of Eclipse.
