After doing a lot of compiling with Ant I get a build failed with a message about the heap. What's this and how can I fix it?

This is my output in my Ant build.xml file. How do I increase the heap size? Thanks Peter


null
ParameterImpl instances: 0
MethodImpl instances: 0
ConstructorImpl instances: 0
SimpleNode instances: 0
SourceClass instances: 0
XDoc instances: 0
DefaultXTag instances: 0
BinaryClass instances: 0
UnknownClass instances: 0
Total memory: 155
Free memory: 94
Try to increase heap size. Can be done by defining ANT_OPTS=-Xmx640m
See the JDK tooldocs.

Hi

I've posted this to the ANT, Maven and other build tools forum as I think it is more appropriate there.

It is sorta covered in the JavaRanch Style Guide.
