This is currently hardcoded. please file a Jira: https://issues.jboss.org/browse/ARQ on the "Extension - Jacoco" component.

If you want to have a go at it, the variable is set here:

https://github.com/arquillian/arquillian-extension-jacoco/blob/master/src/main/java/org/jboss/arquillian/extension/jacoco/client/CoverageDataReceiver.java#L22

And this is a example of using the "extension" element from arquillian.xml:

https://github.com/arquillian/arquillian-extension-byteman/blob/master/src/main/java/org/jboss/arquillian/extension/byteman/impl/common/BytemanConfiguration.java#L118

https://github.com/arquillian/arquillian-extension-byteman/blob/master/src/main/java/org/jboss/arquillian/extension/byteman/impl/client/AgentInstaller.java#L54
