This period of time,EclipseIt's always dead. It's almost a little faster and it will die. It takes several minutes to make people very depressed. A lot of time is wasted. I searched the internet and found many friends with similar situations. I asked for help on the Internet. However, all the methods on the Internet are to modifyEclipse. iniFile to increaseEclipseMemory.

 
 


I tried it and found it was useless. Today, I die again, but a common error is reported. The general idea is:Permgen SpaceMemory overflow. I can't bear it. I searched the internet and found that the Internet is really a good thing. Especially for our own scholars, it is undoubtedly a mentor and friend who gives advice.

 
 


I would like to sum up my experience and the experience of netizens here, hoping to provide some reference value to friends suffering from this problem.

 
 

The solution is as follows:

 
 

InEclipse. iniAdd the following two lines to the configuration file:

-XX: permsize = 128 m

-XX: maxpermsize = 128 m

 
 

Add upstream2After all, myEclipse. iniThe file is as follows:

 
 

-Showsplash

Org. Eclipse. Platform

-- Launcher. xxmaxpermsize

512 m

-Vmargs

-Xms256m

-Xmx512m

-XX: permsize = 128 m

-XX: maxpermsize = 128 m

 
 

The memory size here depends on your physical memory.
