The Software Development Kit Manager
SDKMAN! is a tool for managing parallel versions of multiple Software Development Kits on most Unix based systems. It provides a convenient Command Line Interface (CLI) and API for installing, switching, removing and listing Candidates. Formerly known as GVM the Groovy enVironment Manager, it was inspired by the very useful RVM and rbenv tools, used at large by the Ruby community.
The zip and unzip applications must be installed prior to installing SDK manager.
[codesyntax lang=”bash”]
sudo apt-get install zip sudo apt-get install unzip
[/codesyntax]
The SDK install can commence by issuing the following commands.
[codesyntax lang=”bash”]
curl -s "https://get.sdkman.io" | bash source "$HOME/.sdkman/bin/sdkman-init.sh" sdk version
[/codesyntax]
At this point installations may commence.
[codesyntax lang=”bash”]
sdk list or sdk list >> lst.txt
[/codesyntax]
The following depicts the list of available candidates on this workstation.

Ant (1.10.1) https://ant.apache.org/
Apache Ant is a Java library and command-line tool whose mission is to drive
processes described in build files as targets and extension points dependent
upon each other. The main known usage of Ant is the build of Java applications.
Ant supplies a number of built-in tasks allowing to compile, assemble, test and
run Java applications. Ant can also be used effectively to build non Java
applications, for instance C or C++ applications. More generally, Ant can be
used to pilot any type of process which can be described in terms of targets and
tasks.

Scala (2.12.4) http://www.scala-lang.org/
Scala is a programming language for general software applications. Scala has
full support for functional programming and a very strong static type system.
This allows programs written in Scala to be very concise and thus smaller in
size than other general-purpose programming languages. Scala source code is
intended to be compiled to Java bytecode, so that the resulting executable code
runs on a Java virtual machine. Java libraries may be used directly in Scala
code and vice versa. Scala is object-oriented, and uses a curly-brace syntax.
Scala has many features of functional programming languages, including currying,
type inference, immutability, lazy evaluation, and pattern matching. It also has
an advanced type system supporting algebraic data types, covariance and
contravariance, higher-order types, and anonymous types. Other features of Scala
include operator overloading, optional parameters, named parameters, raw
strings, and no checked exceptions.
$ sdk install scala
