OpenDaylight includes Karaf containers, OSGi (Open Service Gateway Initiative) bundles, and Java class files, which are portable and can run on any Java 11-compliant JVM (Java virtual machine). Any add-on project or feature of a specific project may have additional requirements.
OpenDaylight is written in Java and utilizes Maven as a build tool. Therefore, the only requirements needed to develop projects within OpenDaylight include:
If an application or tool is built on top of OpenDaylight’s REST APIs, it does not have any special requirement beyond what is necessary to run the application or tool to make REST calls.
In some instances, OpenDaylight uses the Xtend language. Even though Maven downloads all appropriate tools to build applications; additional plugins may be required to support IDE.
Projects with additional requirements for execution typically have similar or additional requirements for development. See the platforms release notes for details.
