Overview

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

Usage

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

Configuration

java-type

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

16.04 (Xenial): 8, 9
18.04 (Bionic): 8, 11
