wso2 - Add lib dependencies to Axis2 web service when generating aar file -

i've created axis2 service project developer studio 3.7.1. structure of project following:

projectname -->\src ---->\main ------>\java -------->source code of web service ------>\resources -------->\meta-inf ---------->services.xml -->\lib -->jar dependencies of web service 

from project explorer, when right-click in project , select "export project deployable archive" generate aar file, not contains lib dependencies , have add them hand before deploy aar axis2 server repository. question how can added dependencies automatically?

put lib directory under projectname/src/main/resources package lib aar file.
