Just found out if we specify the dependency like following in the assembly descriptor: | <outputDirectory>modules</outputDirectory> | <useStrictFiltering>true</useStrictFiltering> | <includes> | <include>org.jboss.identity.idm.integration:idm-jboss5-deployer:zip:deployer</include> | </includes> | <unpack>true</unpack> | | we have to specify we depends on idm-jboss5-deployer, neither adding a 'test'/'provided' scope, nor adding the 'optional' attribute work. -Jeff View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4235942#...
