Ant Build scripts - java.lang.OutOfMemoryError   6 comments

Posted at 9:26 am in Flash/Flex

I seem to find getting a ‘java.lang.OutOfMemoryError’ a fairly common occurance when using ANT to build my flash projects ;( There’s not much docmentations out there and none of the solutions I found on the web fixed the issue for me ;( the code example below did…


<!– IMPORTANT added folk=’true’ to help avoid java.lang.OutOfMemoryError –>
<mxmlc file=”${module.class}”
output=”${module.target}”
keep-generated-actionscript=”${module.generateActionscript}”
debug=”${module.debug}”
actionscript-file-encoding=”UTF-8″
optimize=”true”
fork=”true”
compiler.show-binding-warnings=”false” incremental=”false” strict=”true” headless-server=”${flex.compile.headlessServer}”>
<!– IMPORTANT we need to give process more memory to avoid java.lang.OutOfMemoryError –>
<jvmarg line=”-Xms512m -Xmx700m -XX:MaxPermSize=700m -XX:PermSize=512m” />

  2. Thanks Riccardo, Looks interesting. I didn’t see any options to help with the above issue but maybe the wrapper handles it internally?

  3. We had the same issue and several others. Finally we decided to just have the ANT script call the compiler instead of used the Flex Ant Tasks.

  4. Thanks Eric, we need to integrate into ‘Hudson’ to build server-side so as far as I know have to use various Ant tasks.

  5. Hey Paddy,

    Another solution is to change the Eclipse Ant Settings:

    The same thing basically :)
