Part 1.1: Install Java 11

This is an environment setup step and is only required the first time you write a plugin on your computer.

Plugins for Funnelback are written using Java 11. This must be installed in order to develop a plugin for use with Funnelback.

Downloading Java 11 JDK

  1. Open your web browser and visit the Java site.

  2. Download OpenJDK 11 (LTS) for your operating system and choose the HotSpot JVM.

    You must use Java 11 and not a newer version as this is the version used by Funnelback. Other versions of Java (both newer and older) will not be fully compatible.
  3. Install Java by running the installer.

Ensure that java is on your path

After installing java, it should now be available on your path.

  1. Open a terminal or command prompt and run:

    java --version

    A message similar to the one below should be displayed if Java was successfully installed:

    openjdk 11.x.y <date>
    OpenJDK Runtime Environment AdoptOpenJDK (build 11.x.y+z)
    OpenJDK 64-Bit Server VM AdoptOpenJDK (build 11.x.y+z, mixed mode)
