前言：今天下载安装IntelliJ IDEA，随手创建了一个项目，执行Build提示错误。与大多数用于开发JAVA的IDE类似，不做任何配置，编译是不会成功的。因此我尝试对IDEA的配置进行了一点初步探索，顺手记下供同行参考。
目前大多数IDE都没有集成JDK环境，IDEA也是一样，在使用IDEA之前首先要安装JDK，并且配置环境变量。与其他IDE不同之处在于，IDEA不会自动匹配系统的JDK环境，编译时会提示以下错误信息：
Using javac 1.7.0_40 to compile java sources
java: JPS build failed to load optimized file manager for javac:
java.lang.NoClassDefFoundError: com/sun/tools/javac/util/DefaultFileManager
java.lang.NoClassDefFoundError: com/sun/tools/javac/file/JavacFileManager
java: 致命错误: 在类路径或引导类路径中找不到程序包 java.lang
java: Compilation failed: internal java compiler error
IDEA可以为每个项目指定不同版本的JDK，并且需要开发者手动配置项目的所使用的JDK版本。配置方法如下：
（1）单击File | Project Structure菜单项，打开ProjectStructure对话框；
（2）在左侧列表框中，选择SDKs列表项，进入SDK配置页面；
（3）若中间的SDK列表框没有选项，则单击“+”号创建一个JDK列表项；
（4）选择JDK列表项，在SDK ’JDK’选项卡页面中，单击JDK home path项目的浏览按钮，定位JDK安装路径并保存。
2.项目依赖
IDEA内置了Maven环境，默认采用Maven解决项目依赖问题。在新建项目后，项目的路径中会生成pom.xml文件和项目名.iml文件。新建项目后，IDEA不会自动刷新Maven的依赖。以Spring Application为例，新建项目编译时提示以下错误信息：
java: 程序包org.springframework.stereotype不存在
java: 程序包org.springframework.context不存在
java: 程序包org.springframework.context.support不存在
刷新Maven配置的方法为：
（1）右键单击项目；
（2）在弹出菜单中选择Maven|Reimport菜单项。
此时，IDEA将通过网络自动下载相关依赖，并存放在Maven的本地仓库中。另外，可以将Maven的刷新设置为自动，配置方法为：
（1）单击File|Setting菜单项，打开Settings选项卡；
（2）在左侧的目录树中，展开Maven节点；
（3）勾选Import Maven projects automatically选择项。
在Project Structure的Modules选项卡的Dependencies页面中，可以查看Maven所引用的项目。如果未找到指定项目，则对于项目将用红色波浪线提醒。同时，可在该选项卡中修改Maven的依赖项。
后记：在网上看到IntelliJ IDEA所宣称的种种便利，让我产生了一种幻觉——这就是下一代的JAVA开发工具。事实上，除了代码自动补全相较于其它编译器有所提升外，IDEA并没有太多出色之处。短期内恐怕并没有取代Eclipse的可能，更何况Eclipse是免费的。但我还是很期待能够出现更加智能的IDE，即使是收费，只要能够提高开发人员工作效率就是值得的。

Setting heap size in IntelliJ IDEA correctly
正确地设置在IntelliJ IDEA堆大小
问题 (Question)
I have this peculiar problem with running a Processing application in IntelliJ IDEA. I want to save a large image and to do this I run in to the following exception:
Exception in thread "Animation Thread" java.lang.OutOfMemoryError: Java heap space
at java.awt.image.DataBufferInt.(DataBufferInt.java:75)

So clearly there is some memory allocation problem here. The problem is that when i change the .vmoptions files in IntelliJ I get the same results, they have no effect. The "memory" number at the lower right corner of the IDE increases accordingly but it does not seem to let my application allocate more memory.
When I run the processing application in the processing IDE I can manage to save much larger files by setting a large heap size.
In IntelliJ nothing over 256mb seems to make a difference. So my question is how do I set a larger heap size in IntelliJ that allows my application to allocate more memory?
Thank you for your help!
I attach the code for my project in case anyone wants to test it out:
import processing.core.*;
public class TestClassMain extends PApplet
public static void main(String args[])
PApplet.main(new String[] { "--present", "TestClassMain" });
//Global variables
OffScreenRender screenR
int c = 0;
//Variables for offScreenRender
int resFactor = 10;
boolean offScreenRenderSwitch =
public void setup()
background(0);
stroke(255);
//Initialize the render object
screenRender = new OffScreenRender(this, 1, resFactor);
public void draw()
frameRate(30);
stroke(255);
//Check if the render should be saved
if(offScreenRenderSwitch == true){screenRender.startRender();}
background(0,0,0);
rect(20+c,height/2,60,60);
if(offScreenRenderSwitch == true)
screenRender.stopRender();
offScreenRenderSwitch =
public void keyPressed()
//Render the graphics to an offScreen buffer
offScreenRenderSwitch =
import processing.core.*;
* Renders the processingsketch to a .tif file at specified resolution.
public class OffScreenRender
PA // The parent PApplet
OffScreenRender(PApplet p, int width_, int height_, int resFactor_)
//Initialize variables
width = width_;
height = height_;
resFactor = resFactor_;
render = parent.createGraphics(width, height);
//Render the image
void startRender()
parent.beginRecord(render);
render.scale(resFactor);
PApplet.println("first step");
//Render the image
void stopRender()
parent.endRecord();
PApplet.println("second step");
render.save("hej");
PApplet.println("final step");
我有这种奇特的问题在IntelliJ IDEA处理应用程序运行。我想拯救一个大图,为此我在以下异常:异常的线程. lang“动画线程”。在java.awt.image.DataBufferInt OutOfMemoryError:Java堆空间。(DataBufferInt.java:75)java.awt.image.Raster.createPackedRaster(Raster.java:467)java.awt.image.DirectColorModel.createCompatibleWritableRaster java.awt.image.BufferedImage(DirectColorModel.java:1032)。(processing.core.PImage.saveImageIO BufferedImage.java:331)(PImage.java:3117)processing.core.PImage.save(PImage.java:3297)OffScreenRender.stopRender(OffScreenRender.java:38)MainVecField.draw(MainVecField.java:93)processing.core.PApplet.handleDraw(PApplet.java:2305)processing.core.PGraphicsJava2D.requestDraw(PGraphicsJava2D.java:243)processing.core.PApplet.run(PApplet.java:2176)java.lang.Thread.run(Thread.java:724)显然这里有一些内存分配问题。问题是,当我改变。在IntelliJ vmoptions文件我得到相同的结果,他们没有效果。“记忆”号在IDE中增加相应的右下角,但它似乎并没有让我的应用程序分配更多的内存。当我在处理IDE运行加工程序我可以设法保存更大文件通???设置一个大型堆大小。在IntelliJ超过256 mb似乎有所不同。所以我的问题是我怎么设置更大的堆大小在IntelliJ,允许我的应用程序分配更多的内存?谢谢你的帮助!我附上我的项目的代码,以防有人想对其进行测试:import processing.core.*;

public static void main(String args[])
PApplet.main(new String[] { "--present", "TestClassMain" });

if(offScreenRenderSwitch == true){screenRender.startRender();}

render = parent.createGraphics(width, height);
//Render the image

parent.beginRecord(render);
render.scale(resFactor);
PApplet.println("first step");
//Render the image

PApplet.println("second step");
render.save("hej");

最佳答案 (Best Answer)
Changing vmoptions file adjusts the memory used by IntelliJ, but what you're having here is a shortage of memory of JRE that is launched by IntelliJ to execute your application. You need to adjust the memory setting in VM options part of the Run/Debug configuration, for example:
改变vmoptions文件调整使用的内存IntelliJ,但是这里你有什么缺少的记忆所推出的JRE IntelliJ执行您的应用程序。你需要调整内存设置在VM选项运行/调试配置的一部分,例如:
答案 (Answer) 2
IntelliJ shows you the amount used and the current size of the heap.
You are trying to set the maximum which it does not show.
You can attach VisualVM to IntellIJ to see the maximum by running jvisualvm
IntelliJ向您展示使用的数量和当前的堆大小。你想设置的最大,它不显示。你可以把VisualVM IntellIJ看到最大的运行jvisualvm
