如何给 Intellij 编译器更多的堆空间?

问题描述

当我创建一个 Intellij 项目时，我不断收到以下内存不足错误.

When I make an Intellij project, I keep getting the following out of memory error.

我已经在 idea.vmoptions 中增加了我的堆大小:

I already increased my heap size in idea.vmoptions:

-Xms128m
-Xmx2048m
-XX:MaxPermSize=1024m
-XX:ReservedCodeCacheSize=64m
-ea

但我仍然收到此错误:

我错过了什么?

推荐答案

当前版本:

Settings(Mac 上的 Preferences) |构建、执行、部署 |编译器 |构建进程堆大小.

Settings (Preferences on Mac) | Build, Execution, Deployment | Compiler |Build process heap size.

旧版本:

Settings(Mac 上的 Preferences) |编译器 |Java 编译器 |最大堆大小.

Settings (Preferences on Mac) | Compiler | Java Compiler | Maximum heap size.

默认情况下，编译器在单独的 JVM 中运行，因此您在 idea.vmoptions 中设置的 IDEA 堆设置对编译器没有影响.

Compiler runs in a separate JVM by default so IDEA heap settings that you set in idea.vmoptions have no effect on the compiler.
