Hello Vino,
how is base.path defined in your script ?
Do you have a blurb somewhere looking like
<path id="base.path">
<fileset dir="lib">
<include name="*/*.jar"/>
</fileset>
</path>
It looks like base.path is replaced at runtime literally with "<classpath>"

Hi,
I have been encountering same issue.
I got "java.lang.OutOfMemoryError: Java heap space" when I tried to compile
my code with ANT.
So, I tried setting ANT_OPTS env var, that doesn't resolve the issue
permanently and the issue occurred intermittently.
Then I tried setting fork attribute in my build.xml, which brought up a
following exception

The javac tag I used in my build.xml is:
<javac srcdir="${src}" destdir="${classDst}" debug="${debug}"
fork="yes"
memoryInitialSize="256m"
memoryMaximumSize="256m"
executable="${env.JAVA_HOME}/bin/javac"
source="${compiler.opts.vm.source}"
target="${compiler.opts.vm.target}"
includes="${projectDir}/xxx/**"
excludes="${projectDir}/xxxTest/**" >
<classpath refid="base.path" />
</javac>
I have even tried with following javac tag in build.xml:
<javac srcdir="${src}" destdir="${classDst}" debug="${debug}"
fork="yes"
memoryInitialSize="512m"
memoryMaximumSize="512m"
executable="${env.JAVA_HOME}/bin/javac"
deprecation="off"
optimize="off"
verbose="no"
source="${compiler.opts.vm.source}"
target="${compiler.opts.vm.target}"
includes="${projectDir}/xxx/**"
excludes="${projectDir}/xxx/Test/**" >
<classpath refid="base.path" />
</javac>
Please help me to get rid of this issue, I have been struggling with this
issue for the last 5 days.
Thanks in advance,
_Vino

memoryMaximumSize?
you should try with another compiler if you were using Sun Javac, try
jikes or even better eclipse compiler
(org.eclipse.jdt.core.JDTCompilerAdapter)

Subject: Frequent java.lang.OutOfMemoryError: Java heap space error
Hello all,
I am running my product build with cruisecontrol using ant 1.7.0. I have
set
ANT_OPTS=-Xms=1536m -Xmx1536m, but still I am getting below mentioned
error,
I have searched mail archive, but I see ANT_OPTS settings, which I have
already set, I get the following error :
[javac] The system is out of resources.
[javac] java.lang.OutOfMemoryError: Java heap space
Am I doing right to set ANT_OPTS variable to increase the heap size ? I am
running my build machine using Windows XP with 2.0 Gigabyte of physical
RAM.
Does somebody know how to handle this ? It is more frequent now.
Thanks in adavnace for thoughts.
Regards,
Ravi
