我在Mountain Lion上使用IDEA 12 Leda.我想增加IDE可以使用的最大内存.我将Info.plist文件中的VMOptions设置为 -Xmx2048m -ea -XX:+HeapDumpOnOutOfMemoryError -Xverify:none -Xbootclasspath/a:../lib/boot.jar

当我打开IDEA时,我仍然看到最大内存为711m.

jps -v 显示我的VMOptions已加载,但它已被以下选项取代.

29388  **-Xmx2048m** -ea -XX:+HeapDumpOnOutOfMemoryError -Xverify:none -Xbootclasspath/a:../lib/boot.jar -Xms128m **-Xmx800m** -XX:MaxPermSize=350m -XX:ReservedCodeCacheSize=64m -XX:+UseCodeCacheFlushing -XX:+UseCompressedOops -Didea.paths.selector=IdeaIC12 -Dsun.java2d.noddraw=true -Didea.max.intellisense.filesize=2500 -Didea.dynamic.classpath=false -Didea.jars.nocopy=false -Dsun.java2d.d3d=false -Dapple.awt.fullscreencapturealldisplays=false -Dapple.laf.useScreenMenuBar=true -Djava.endorsed.dirs= -Dswing.bufferPerWindow=false -Didea.fatal.error.notification=enabled -Didea.cycle.buffer.size=1024 -Didea.popup.weight=heavy -Didea.xdebug.key=-Xdebug -Dapple.awt.graphics.UseQuartz=true -Dsun.java2d.pmoffscreen=false -Didea.no.launcher=false -DCVS_PASSFILE=~/.cvspass -Didea.use.default.antialiasing.in.editor=false -Dcom.apple.mrj.application.live-resize=false -Didea.smooth.progress=false
29392 Jps -Dapplication.home=/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home -Xms8m

哪里-Xmx800来的？我需要删除它.

当我创建一个Intellij项目时,我不断收到以下内存错误.

我已经增加了我的堆大小idea.vmoptions:

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

但我仍然得到这个错误:
