do you have any idea why I could get a 'Exception in thread "main" java.lang.OutOfMemoryError: Java heap space' error when building my android app, even though I added -vmargs -Xmx1024M -Xms512M to the eclipse arguments ?
I would like to know what error could I have made that would trigger such an error at build time, as it would appear to me that only a bug in eclipse or maven could produce such an error at build time.
I am using run as maven install to build my application (with the maven android eclipse plugin). Run as-> 'maven package' also produces the same build failure, after waiting roughly 1min30.
I have a desktop computer with 3GB of memory, and my application isn't nearly that big.
Thanks.
Add -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/some/path to your jvm args so that when it runs out of memory it will dump out the heap. You can then use Eclipse Memory Analyser or jhat to browse the heap and diagnose where the problem might be.
Update: Try increasing the memory of your maven android plugin. In your pom.xml, add a JVM argument for Xmx to the plugin configuration:
<plugin>
<artifactId>maven-android-plugin</artifactId>
<configuration>
<jvmArguments>
<argument>-Xmx1500m</argument>
</jvmArguments>
</configuration>
</plugin>
Your Eclipse JVM arguments do not matter. You have to increase the heap of the compiler.
I am quoting http://javahowto.blogspot.com/2006/06/fix-javac-java-lang-outofmemoryerror.html
If [...] you're running Eclipse, go into your "run As" dialog for your Build.xml and add -Xms256m -Xmx256m to the "VM Arguments" text box
I experienced this Conversion to Dalvik format failed: Unable to execute dex: Java heap space. increasing the all of the values in the eclipse.ini file didn't help. This happened to me after I upgraded my ADT plugin from 12 to 16. I changed the Android SDKs that were pointed to my existing projects prior to the upgrade (from the android sdks that were connected on my previous adt I changed them to the android sdks that were connected to my new adt) and it solved the issue for me. hope this helps. and if it helps someone please vote for plus 1 this.
If increasing does not respond then I would suggest to you that check the line count for each class you wrote. It can be a compiler problem if there are a lot of objects so try to partitioning methods and/or copy them into new classes if one or more of the classes have 3000+ lines.

As I didnt get any solution from previous similar question,I am raising this issue.
I have 8GB RAM,32 bit window 7 os,32 bit eclipse and 32 bit JVM. I used to compile my GWT project successfully.But after adding some uploading and mobile-related jars,I get this Out of memory exception while compiling this project.
I have tried to change the VM arguments,but got no success.Then I moved to 64 bit OS,64 bit eclipse,64 bit JVM, and tried to assign more Xmx parameter in the vm argument,but its not taking more than 1.5GB where as I have 8 GB RAM,Hence no success while compiling. Need Help!!
This is because, you may be using lots of servlets or GWT files.
As far as you are using 64bit OS this should work with -Xmx 4096m. Try
checking the path sometimes the JRE path will be pointing to x86 if
so change to JRE installed on x64.
If the VM arguments is not working for more than 2048m then probably
it will be a issue with JRE(for x86) or OS architecture(x86).
If you are using maven to compile your gwt code :
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>gwt-maven-plugin</artifactId>
...
<configuration>
<extraJvmArgs>-Xmx2048m</extraJvmArgs>
</configuration>
</plugin>
I hope this can help you.
Changing to 64 bits was the right thing to do, but you have to make sure that Eclipse is using the right version of Java.
Check if you're pointing to the right version of Java in Window > Preferences > Java > Installed JRE
I have 8GB RAM,32 bit window
Fail. 32-bit operating system can technically only managed a maximum of 4 GB of RAM
I'm using IntelliJ IDEA to develop my Java application. I'm frustrated with the fact that the first compilation of a project (or a complete rebuild) takes very long, about 15 min (and is very CPU-intensive). The project is composed from a couple of hundreds of Java classes, but compiling it with Eclipse just need 1-2 minutes.
Are there any compilation options that I can set in order to speed up this step?
UPDATE
My configuration: SSD, 64GB RAM, Xeon E5-1660, Win 7 Ultimate
Compilation time (Rebuild):
Eclipse: 30s
IntelliJ IDEA with Eclipse compiler 45s
IntelliJ IDEA with javac compiler: more than 10 minutes (!)
Number of java classes ~5000
Change the following setting (Build process heap size) to some large value
You can use the Eclipse compiler from IntelliJ IDEA.
Enable the Eclipse compiler from Settings -> Compiler -> Java Compiler: "Use compiler:" (change from Javac to Eclipse).
update: Here's my compilation times for a full rebuild, using IntelliJ IDEA 13 on a fairly large project:
Using javac 1.7.0_45 to compile java sources
Compilation completed successfully with 60 warnings in 27 sec
Using eclipse compiler to compile java sources
Compilation completed successfully with 652 warnings in 26 sec
So there seems to be something strange with your setup.
Answer from IntelliJ Support:
Try 13.0.2 from
http://confluence.jetbrains.com/display/IDEADEV/IDEA+13+EAP .
Disable the option to clean output directories on rebuild in the
compiler settings.
You can also increase the heap size in the file Intellij IDEA\bin\idea.exe.vmoptions. For example try these (assuming you have a lot of RAM):
-Xmx6g
-Xms6g
-XX:MaxPermSize=512m
-ea
-server
-XX:+UseConcMarkSweepGC
Having done this, you need to start idea with idea64.exe because the default 32bit version will not be able to use the big ram.
We put our projects on a SSD drive and this speed up the IDEA
rebuild significantly (about half the time).
I don't think you are comparing the same thing IDEA <-> eclipse somehow eclipse must have done some work already in the background or has a cache somewhere but I don't know eclipse well.

I have updated the jdev.conf file to include the following, but still receive the error:
AddVMOption -XX:MaxPermSize=512M
AddVMOption -Xmx512M
AddVMOption -Xms512M
Furthermore, this project opens just fine without issue on a colleague's computer, where the jdev.conf file -XX:MaxPermSize=512M switch is set to 256M and the other 2 switches are not present.
I've spent the afternoon playing with different settings, trying to discover the difference, and I am left stumped. Is there something I'm missing? When I try to bump the setting to higher memory limits, JDeveloper fails to start the Java machine (I suspect that is related to memory allocated to Java itself), though it shouldn't be necessary, as the app works fine on my coworker's computer with half the memory allocated to JDeveloper.
I faced the same issue and it get resolved with the help of below link :
Fixing java.lang.OutOfMemory Java Heap Space error in JDeveloper
Beside changing the configration fieles (jdev.conf and ide.conf) to have the commands
JDEV.CONF
AddVMOption -XX:MaxPermSize=256M
IDE.CONF
AddVMOption -Xmx768M
AddVMOption -Xms256M
See also this link:
Jdeveloper throwing Out of Heap Space error with SVN
Beside, stop versioning option for Jdeverlper as follow:
In JDeveloper -> Choose Versioning menu -> Choose Configure -> Uncheck “Versioning support for Subversion”
You can use some standalone SVN clients such as TortoiseSVN for
versioning
Egh. Simple, REALLY obvious solution that we just somehow overlooked. He is running an older version of JDeveloper. Installed that version, everything works.
Once in a while I'll get the following error when the Gradle STS extension tries to execute my project's gradle build script after launching Eclipse 3.7 (Indigo) with the Gradle STS extension installed,
Unable to start the daemon process. The exit value was: 1.
This problem might be caused by incorrect configuration of the daemon.
For example, an unrecognized jvm option is used.
Please refer to the user guide chapter on the daemon at http://gradle.org/docs/current/userguide/gradle_daemon.html
Please read below process output to find out more:
-----------------------
Error occurred during initialization of VM
Could not reserve enough space for object heap
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
Could not fetch model of type 'EclipseProject' using Gradle distribution 'http://services.gradle.org/distributions/gradle-1.0-bin.zip'.
And here are my system specs:
Windows 7 32-bit
Eclipse 3.7 32-bit
Java jdk1.7.0_07 32-bit
Is this a known bug with this plugin? Any idea on how to fix it?
In eclipse, go to Window, Preferences, Gradle, Arguments
and add the gradle jvmargs -Xms128m -Xmx512m in the dialog:
Sounds like once in a while, your system can't reserve enough memory to start the Gradle daemon. Does the project have a gradle.properties containing memory settings (org.gradle.jvmargs)? Or, do you have a gradle.properties in ~/.gradle?
I had same problem with Gradle projects importing. (Windows 7 64-bit, sts-3.2.0.RELEASE 32bit, Java jdk1.7.0_13 32-bit).
Solved creating gradle.properties file in project directory(=sts workspace) with content: org.gradle.jvmargs=-Xms128m -Xmx512m.
Note that -Xmx=512m is max size of JVM memory I can use on my system. Bigger Xmx memory sizes leads to described error.
I am developing an application with GWT and GAE. When I try to rebuild it or create an artifact I get a lot of errors shown below in the picture.
I searched google and Stack Overflow and I got some answers but not to my particular problem.
From what I understand I get the error because my garbage collector consumes a lot of memory.
here is the main error Exception in thread "main" java.lang.OutOfMemoryError: GC overhead limit exceeded.
OK, I fixed the problem. just increase the memory that the virtual machine needs to compile the project. Previously it was 128 and now I change it be 512. as my project grown it needed more memory to compile the classes of the project.Here is how to do that in Injtellj IDEA. right click on the project
module -> open module settings -> Modules -> GWT -> compiler maximum heap size (Mb) -> changed to 512.
NOTE: In Ideal Intellij 12+ The project settings is in : File -> Project Structure OR Ctrl+Alrt+Shitf+S
I had encountered the same problem
Exception in thread “main” java.lang.OutOfMemoryError: GC overhead limit exceeded
and when I tried to fix this error it showed the same error. So don't panic and just increase size a little more by setting this option in Run->Run Configurations->Click on arguments->inside VM arguments type
-Xms1024M -Xmx2048M
Xms- for minimum limit
Xmx- for maximum limit
Adio's answer is correct, except that I needed to change it to 1000Mb when we added the "gwt-mobile" library - 512 Mb was still giving me the "GC overhead limit" error. I think 128Mb is a pretty poor default - that didn't work for us even when we began writing our app.
Changing the config through the project properties in netbeans didn't work.
My solution was to edit the nbproject/gwt.properties with:
# Additional JVM arguments for the GWT compiler
gwt.compiler.jvmargs=-Xmx1024M
I tried all the suggestions in a number of posts on the net and none of them worked.
After much experimenting, in the end I found that using the G1GC garbage collector on OSX made a big difference for me. If you are using ANT then you must make sure the build file launches the compiler with the G1GC garbage collector
In NetBeans 8.2 do the following
Right click on Project Name -> Properties -> Google Web Toolkit
Modify JVM Arguments to -Xmx512M
Click Ok
Run again
This work for me on Windows 10, Netbeans 8.2, GWT 2.8.2, JDK 1.8
