This is a layered charm that generates a deployable OpenJDK charm. Source for this charm is available at github.


This subordinate charm implements the java interface and requires a principal charm that provides the java relation endpoint. Example deployment:

juju deploy ubuntu-devenv
juju deploy openjdk
juju add-relation ubuntu-devenv openjdk



This determines which OpenJDK packages to install. Valid options are jre or full. The default is jre, which will install the OpenJDK Java Runtime Environment (JRE). Setting this to full will install the OpenJDK Java Development Kit (JDK), which includes the JRE.

Switch between the JRE and full (JRE+JDK) with the following:

  juju set openjdk java-type=full

Major version of Java to install. This defaults to 8 and installs openjdk-8-[jre|jdk]. Valid options for Ubuntu releases are:

  • 14.04 (Trusty): 6, 7, 8
  • 16.04 (Xenial): 8, 9
  • 18.04 (Bionic): 8, 11

Switch between Java8 and Java9 with the following:

juju set openjdk java-major=9
