The Alfresco Software Development Kit (Alfresco SDK) is a fundamental tool provided by Alfresco to developers to build customizations and extensions for the Alfresco Digital Business Platform. It is based on Apache Maven and is compatible with major IDEs. This enables Rapid Application Development (RAD) and Test Driven Development (TDD).
Alfresco SDK 3.0 is released under Apache License version 2.0 and supports Alfresco Content Services both in Community Edition and Enterprise Edition. If you're an Enterprise customer, please check the Alfresco SDK Support status for the version you're using. If your version is in Limited or Full Support and you need help, contact our Support team http://support.alfresco.com.
