Increasing Memory Heap To prevent the build process from running out of memory, you can increase the amount of memory allocated to the process. By default, the memory heap is 128 MB, but for large projects you may need more. In this section: • • Increasing memory heap of the build process • dialog box. • In the Maximum heap size field, type the required amount of memory.

Important notes Please note the following: The memory heap of the build process is independent of IntelliJ IDEA memory heap, and is released after the build process is complete. The memory heap available to IntelliJ IDEA may be changed by editing the corresponding VM options. To avoid editing files in the IntelliJ IDEA installation folder, one should: • Do one of the following: • Use the main menu command Help Edit Custom VM Options to create a copy of the idea.vmoptions file in the user home. Refer to for details. • Copy the existing file from the IntelliJ IDEA installation folder somewhere and save the path to this location in the environment variable IDEA_VM_OPTIONS. • Copy the existing file /bin/idea.exe.vmoptions or /bin/idea64.exe.vmoptions from the IntelliJ IDEA installation folder into the location under your user home. • Edit this file in the new location.

If IDEA_VM_OPTIONS environment variable is defined, or the *.vmoptions file exists, then this file is used instead of the one located in the IntelliJ IDEA installation folder.

> Running Eclipse After installing the Eclipse SDK in a directory, you can start the Workbench by running the Eclipse executable included with the release (you also need at least a JDK6 or JRE 6, not included with the Eclipse SDK). On Windows, the executable file is called eclipse.exe, and is located in the eclipse sub-directory of the install.

If installed at c: eclipse-SDK-4.4-win32, the executable is c: eclipse-SDK-4.4-win32 eclipse eclipse.exe. Note: Set-up on most other operating environments is analogous. Special instructions for Mac OS X are listed. Allocating enough memory and solving OutOfMemoryErrors By default, Eclipse will allocate up to 384 megabytes of Java heap memory. This should be ample for all typical development tasks. However, depending on the JRE that you are running, the number of additional plug-ins you are using, and the number of files you will be working with, you could conceivably have to increase this amount.

Emulator mac os 9. Eclipse allows you to pass arguments directly to the Java VM using the -vmargs command line argument, which must follow all other Eclipse specific arguments. Thus, to increase the available heap memory, you would typically use: eclipse -vmargs -Xmx with the value set to greater than '384M' (384 megabytes -- the default). When using an Oracle JRE, you may also need to increase the size of the permanent generation memory. The default maximum is 64 megabytes, but more may be needed depending on your plug-in configuration and use. When the VM runs out of permanent generation memory, it may crash or hang during class loading.
