Build fail in java

Question

I am try to build my java application in command prompt, but it fails as..

compile-core:
    [javac] Compiling 1085 source files to c:\conet\app\build\core
    [javac]
    [javac]
    [javac] The system is out of resources.
    [javac] Consult the following stack trace for details.
    [javac] java.lang.OutOfMemoryError: Java heap space

BUILD FAILED
C:\conet\app\build.xml:324: Compile failed; see the compiler error output for details.

Total time: 1 minute 5 seconds

Any solution for this type of problem.

Since you're using ant, you should increase the available heap size for compilation. Add this to your build.xml compilation target:

memoryinitialsize="256m"
memorymaximumsize="1024m"

Info taken from here.

in which file I have to add this – Amit Battan Dec 02 '10 at 07:11
@Amit: build.xml; if you're not sure where to put it, edit your question and add its contents so we can see what it looks like – darioo Dec 02 '10 at 08:33
I set fork attribute to true through your link in build.xml and solved .. Thanks darioo – Amit Battan Dec 02 '10 at 08:56

If Java runs out of memory, the following error occurs:

Exception in thread "main" java.lang.OutOfMemoryError: Java heap space This can have two reasons:

Your Java application has a memory leak. There are tools like YourKit Java Profiler that help you to identify such leaks.
Your Java application really needs a lot of memory (more than 128 MB by default!). In this case the Java heap size can be increased using the following runtime parameters:

javac -Xms<initial heap size> -Xmx<maximum heap size>

Defaults are:

javac -Xms32m -Xmx128m

Please increase the memory accordingly as required.

I have done javac -Xms512m -Xmx512m... but still same problem – Amit Battan Dec 02 '10 at 07:10
What is the size of your RAM ? – Mohamed Saligh Dec 02 '10 at 07:14
You could get the free space of your VM, too (which is your bottle neck); Also you can go through this thread: http://stackoverflow.com/questions/37335/how-to-deal-with-java-lang-outofmemoryerror-java-heap-space-error-64mb-heap-s – Mohamed Saligh Dec 02 '10 at 07:26
