# Class: java
|
|
#
|
|
# This module manages the Java runtime package
|
|
#
|
|
# Parameters:
|
|
#
|
|
# [*distribution*]
|
|
# The java distribution to install. Can be one of "jdk" or "jre",
|
|
# or other platform-specific options where there are multiple
|
|
# implementations available (eg: OpenJDK vs Oracle JDK).
|
|
#
|
|
# [*version*]
|
|
# The version of java to install. By default, this module simply ensures
|
|
# that java is present, and does not require a specific version.
|
|
#
|
|
# [*package*]
|
|
# The name of the java package. This is configurable in case a non-standard
|
|
# java package is desired.
|
|
#
|
|
# [*package_options*]
|
|
# Array of strings to pass installation options to the 'package' Puppet resource.
|
|
# Options available depend on the 'package' provider for the target OS.
|
|
#
|
|
# [*java_alternative*]
|
|
# The name of the java alternative to use on Debian systems.
|
|
# "update-java-alternatives -l" will show which choices are available.
|
|
# If you specify a particular package, you will almost always also
|
|
# want to specify which java_alternative to choose. If you set
|
|
# this, you also need to set the path below.
|
|
#
|
|
# [*java_alternative_path*]
|
|
# The path to the "java" command on Debian systems. Since the
|
|
# alternatives system makes it difficult to verify which
|
|
# alternative is actually enabled, this is required to ensure the
|
|
# correct JVM is enabled.
|
|
#
|
|
# [*java_home*]
|
|
# The path to where the JRE is installed. This will be set as an
|
|
# environment variable.
|
|
#
|
|
# Actions:
|
|
#
|
|
# Requires:
|
|

|
|
# Sample Usage:
