Bazel

ONOS is a Java based platform. In order to be able to compile the code, you need to install Oracle Java 1.8. The OpenJDK equivalent might work, but it's not suggested, since it has never been tested.

Since Oracle had an license update on April 16 2019, anyone who want to download java8 has to register account, the apt methods of installing will not work.

Go to Oracle JDK download website, login and download the tar ball : jdk-8uxxx-linux-x64.tar.gz

Install bazel

currently  bazel.0.27.0 is the lastest one that support building ONOS, please refer to Install bazel for how to install bazellarge project comprising of multiple relatively independent modules that lend themselves to be built in parallel, resulting in much faster. This is why the project chose to build via Bazel. Developers should install Bazel (0.27.0 at the time of writing) before they can build the project themselves.
