java.lang.OutOfMemoryError: Java heap space

[EvilAngel]

Hi all,

I am following the howto to install OX Hyperion http://typo3.open-xchange.com/wiki/i...._Installation

I installed all 3rd party libraries.

When i launch:

cd /tmp/open-xchange/
ant -Dlib.dir=/opt/open-xchange/lib install

I have this message:

compile:
    [javac] Compiling 959 source files to /tmp/open-xchange/build
    [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
/tmp/open-xchange/build.xml:111: Compile failed; see the compiler error output for details.

The server is Debian Etch with 1 Go RAM and dual-core AMD CPU.

Any ideas ?

Thanks

In and of itself java (and in turn ant) just uses 64Mb of your memory, trying to behave itself. Quite a testimony to java being about 10yrs old, I guess.
Try:

ant -Xmx512m -Dlib.dir=/opt/open-xchange/lib install

Exactly.

While searching I also found another way to solve it:
Create a ~/.ant/ant.conf file with:
ANT_OPTS="-Xms512M -Xmx512M"
inside.

Now Ant is working fine.
