Limits the maximum memory heap size that the JVM can allocate for running IntelliJ IDEA. The default value depends on the platform. If you are experiencing slowdowns, you may want to increase this value, for example, to set the value to 2048 megabytes, change this option to -Xmx2048m .
To increase the Application Server JVM heap sizeLog in to the Application Server Administration Server. Navigate to the JVM options. Edit the -Xmx256m option. This option sets the JVM heap size.
Current version:
Settings (Preferences on Mac) | Build, Execution, Deployment | Compiler |
Build process heap size.
Older versions:
Settings (Preferences on Mac) | Compiler | Java Compiler | Maximum heap size.
Compiler runs in a separate JVM by default so IDEA heap settings that you set in idea.vmoptions have no effect on the compiler.
Since IntelliJ 2016, the location is File | Settings | Build, Execution, Deployment | Compiler | Build process heap size.
I had a similar problem with Ant build (started by hand from IDEA GUI). In my case there was the right solution to right click on the Ant task, choose properties and set a higher value to "Maximum heap space (Mb):" and "Maximum stack space (Mb):" input fields.
To resolve this issue follow the below given steps-
1). In inteli Go to File> Setting Option and Search for Vm Option In the field of Vm Option for Importer give value -Xmx512m. Intelij Setting Options
2). Go to Control Pannel Select View by :Large icons then Go to Java one promp window will appear with name java control pannel then go to java Java VM Options
select view option. java view options
In Java Run time Environment Setting pass Run time Parameters as -Xmx1024m.
3). If above given options does not work then change the size of pom.xml
