Axelor sous eclipse

" The application project is configured to be eclipse webtool compatible. Create a tomcat7 server, add the axelor-demo module and run the server.

You can use axelor shell utility or the included gradlew script to generate code or build the project from external terminal. In this case, always refresh eclipse workspace to see the updated source in eclipse"
