I have installed M2Eclipse plugin for maven , but after installing plugin when i tried to proceed then eclipse shows error's and get crashed,slow or hanged.
It shows following error : Background Indexer Crash Recovery
java heap space .. and many more similar exceptions.
I have increased heap size in eclipse.ini file but this issue was not get solved. I have also increased heap space using command : java -Xms -Xmx through command line ,still its not working.
set eclipse.ini
-Xms512m
-Xmx1024m
solved my m2eclipse retrieving prototype problem
I met the same problem, but, it's not working to increase the heap space. So, I created a new workspace, amazing, everything was normal: I could see the archetypes list again. I guessed something wrong with the m2eclipse plugin, So, I deleted the folders that whoes name contains characters 'm2e' in the path 'workspace.metadata.plugins'. And then, I restarted the eclipse, everything returned to normal.The problem has been solved.
In eclipse.ini, I changed
-Dosgi.requiredJavaVersion=1.7 -Xms40m -Xmx1024m -XX:MaxPermSize=512m
to
-Dosgi.requiredJavaVersion=1.7 -Xms512m -Xmx1024m -XX:MaxPermSize=512m
In other words, I raised the initial heap size. That resolved it for me. My allowed heap size when actually running Eclipse Indigo rose from 64 MB to 169 MB
I did all of the above, to no change -
I ended up just creating a new workspace! And everything went back to normal ..

Mine worked by change
-Dosgi.requiredJavaVersion=1.7 -Xms512m -Xmx1024m -XX:MaxPermSize=512m

Recently I have lots of problems with eclipse, it keeps on crashing, closing abruptly, don't work well at all.
It happens too much, like in every 10 -15 minutes.
The CPU and RAM are 50% free when this happens.
This is the eclipse.ini file:
-startup
plugins/org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.200.v20120522-1813
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
--launcher.defaultAction
openFile
-vmargs
-Xms40m
-Xmx512m
What is the problem ? It's really bothering!
add the line
-XX:-UseCompressedOops
to eclipse.ini
but if you are using this windows 7 then rather add
-XX:+UseCompressedOops
Even try running ecipse as administrator. If this even works then try opening with java.exe instead of javaw.exe. I hope this will work!
open eclipse.ini or eclipse configuration file and add below command as first line
-clean
now save and try to open eclipse.
this worked for me.
Have a nice time.
Create a new Workspace.
Import your stuffs into it.
That worked for me.
First before you do ANYTHING check the log: Look at the workspace/.metadata/.log file. In my case it was just some error with a subversion update using subclipse.
Navigate to a hidden directory in your Eclipse Workspace named .metadata, delete it, and start eclipse. Files in the .metadata directory seem to cause recurrent problems once Eclipse begins to crash.
On eclipse neon.
On a specific project.
Last thing some days ago was install lombok.
For some days everythig was ok.
From yestarday same problem, eclipse crash after some seconds, after open.
Removed from eclipse.ini this line.
-javaagent:D:\eclipse-neon\lombok.jar
Now eclipse restarted to work
I have a plugin project. When i debug this as an eclipse application, in the 2nd eclipse that opens, I want to open Project explorer window. As soon as I click on the button to do this, I get java.lang.OutOfMemoryError: PermGen space. I tried changing the PermGen space in the preference, but it did not help. Can any one please suggest a solution.
You should add the -XX:MaxPermSize=256m or 512m to the Window>Preferences>Java>Installed JREs preference page. Edit a JRE and add it to the Default VM arguments tab.
The eclipse native launcher uses the eclipse.ini to add extra permgen arguments to Oracle JVMs, but that information is not used during runtime launching.
What if you try to extend the memory of eclipse when it starts. To do that simply open the .ini file (inside your eclipse folder) and edit the lines that refer to permSize and memory size:
e.g.
-XX:MaxPermSize=500m
-Xms500m
-Xmx2000m
If you don't want to set the permgen size for EVERY launch, you can also add the Parameter to the Debug Configuration.
Run > Debug Configurations
Choose the "Eclpise Application"-Configuration on the right side and choose Arguments in the Tabs.
Add -XX:MaxPermSize=512m to the VM arguments:
-Dosgi.requiredJavaVersion=1.6 -Xms256m -Xmx4g -Dfile.encoding=UTF-8 -XX:MaxPermSize=512m
I often get this error "Operation linking viewer selection with current editor finished with errors" in Eclipse Galileo.
Once this error pops up no UI events is working in the IDE , i cant even able to close it also. Every time i have to go to task manager to stop the process , after this IDE works fine for some 5 min and again it display the same error as mentioned above.
i don't know what is happening , can you guys please help.
Just switch your Project Explorer to the Flat package presentation in Eclipse. It works :)
see details here: https://bugs.eclipse.org/bugs/show_bug.cgi?id=530450#c7
Per the Eclipse manual:
PermGen is the permanent generation of objects in the VM (Class names, internalized strings, objects that will never get garbage-collected). An easy, if somewhat memory-hungry fix is to enlarge the maximum space for these objects by adding
-XX:MaxPermSize=128M
as an argument to the JVM when starting Eclipse. The recommended way to do this is via your eclipse.ini file.
If you are getting OutOfMemoryErrors while running Eclipse, the VM can be told to let the heap grow to a larger amount by passing the -vmargs command to the Eclipse launcher.
-vmargs
-Xms512m
-Xmx1024m
Alternatively, you can invoke the Eclipse executable with command-line arguments directly, as in
eclipse [normal arguments] -vmargs -XX:PermSize=512M -XX:MaxPermSize=1024M -Xmx1024M [more VM args]
Even with recent versions of Eclipse and Flat Package presentation, if you have a lot of large projects loaded this can still be a problem.
I've found however that if you break up your projects into working sets and minimise the amount of projects/tree nodes open by selecting a working set it can really speed up Eclipse and mitigate this problem.
I had this problem (Version: Photon Release (4.8.0)) and I fixed it by removing all breakpoints.
I'm having some weird problems with Eclipse lately. I haven't installed any new plugins that I think could have caused them (xcarecrows and m2eclipse, both already removed).
The problem is that Eclipse sometimes hangs on random things. Sometimes simply by opening it, sometimes clicking anywhere on the GUI while it's loading something, sometimes while pasting code (Java). But the biggest problem is that it doesn't unfrezze.
AFAIK the problem started when I experimented with settings in eclipse.ini, but I can't be sure because it was some time ago and it hasn't happened all that often.
I don't know how to find out what could be causing this so I'm asking here, maybe someone can suggest some diagnostics.
Also, here's my eclipse.ini, maybe there's something wrong in it:
-showlocation
-showsplash
org.eclipse.platform
--launcher.defaultAction
openFile
-vm
C:/Program Files/Java/jdk1.6.0_22/jre/bin/server/jvm.dll
-vmargs
-Dosgi.requiredJavaVersion=1.6
-Xms128m
-Xmx384m
-Xss4m
-XX:PermSize=128m
-XX:MaxPermSize=384m
-XX:CompileThreshold=5
-XX:MaxGCPauseMillis=10
-XX:MaxHeapFreeRatio=70
-XX:+CMSIncrementalPacing
-XX:+UnlockExperimentalVMOptions
-XX:+UseG1GC
-XX:+UseFastAccessorMethods
The canonical reference for this kind of issues is How to report a deadlock in Eclipse.
You will need to aquire the thread dumps of all threads. Perhaps it will give you insight of a bad plugin, or perhaps Eclipse itself.
If you suspect this is memory-related, you should read Getting a heap dump and analyse the resulting file in the Eclipse Memory Analyzer
I've looked on the web for a while and can't seem to find the setting to increase the memory allocated to OC4J when launching from Eclipse. Does anyone know where the setting is?
Thanks.
You can add memory setting in the OC4J_JVM_ARGS environment variable. For example you could have something like:
OC4J_JVM_ARGS=-Xmx512m
You could add others if you want:
OC4J_JVM_ARGS=-XX:PermSize=256m -XX:MaxPermSize=256m -Xms1024m -Xmx2048m
Now, I never have run OC4J from Eclipse (only standalone), but you could do the same by selecting your Server view, then Open launch configuration and in the Arguments tab add the values to the VM arguments section directly like:
-Xmx512m
or
-XX:PermSize=256m -XX:MaxPermSize=256m -Xms1024m -Xmx2048m
