Unfortunately ANT_OPTS gets overrided by build.sh So there are 3 ways to go: 1. Change build.sh 2. Make server config task set the java property based on the existence of the ant property "jbossas.startup.timeout" 3. Use ant command instead build.sh Probably #2 is more straightforward followed by #1. I can help with waht you consider better.
