OutOfMemory error

["Hertel, Oliver" <Ol...@Dresdner-Bank.com>]

Hello,

I get an OutOfMemoryError like this:

    [javac] The system is out of resources.
    [javac] Consult the following stack trace for details.
 
    [javac] java.lang.OutOfMemoryError
    [javac]     <<no stack trace available>>

        at org.apache.tools.ant.Main.main(Main.java:234)

I'm using this build.xml:

<?xml version="1.0"?>
<project name="ffp_src" default="compile" basedir="/data/work/build">
  <!-- set global properties for this build -->
  <property name="release" value ="8.0_dev" />
  <property name="src" value="${release}_ux/src" />
  <property name="build" value="${release}_ux/serverclasses" />
 
  <target name="init">
    <!-- create the time stamp -->
    <tstamp/>
  </target>
 
  <target name ="compile" depends="init">
    <!-- compile the java code from ${src} into ${build} -->
    <javac srcdir="${src}"
           destdir="${build}"
           memoryInitialSize="32m"
           memoryMaximumSize="256m"
    />
  </target>
</project>

Any hints? There are lots of source files in there, but the machine has
surely enough memory (4 GB).

MfG,

Oliver Hertel

Javac is executed within in the same JVM as Ant. Unless you've changed the
Ant startup scripts, it's using the default JVM memory settings (-Xmx64m I
think). You need to set the ANT_OPTS environment variable to something like
this:

ANT_OPTS=-Xmx256m

Our project compiles about 1800 source files successfully with that setting.

Ciao,
Gordon
