Install Software Requirements

Java Development Kit (JDK) & Java Runtime Environment (JRE)

In order to get the proprietary Oracle Java 8 packages, run the following:

sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installer
sudo update-java-alternatives -s java-8-oracle

 

To set the JAVA_HOME environment variable for the installed JDK:

export JAVA_HOME=/usr/lib/jvm/java-8-oracle
echo "export JAVA_HOME=$JAVA_HOME" | sudo tee -a /etc/environment

 

To obtain the Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files required for unlimited strength encryption used in DCDT, run either of the following sets of commands:

sudo apt-get install oracle-java8-unlimited-jce-policy

Git CLI

Run the following:

sudo apt-get install git

Apache Maven

Maven must be installed manually because the minimum version of Maven that must be installed is 3.1.1 and on 14.04 LTS, the default version of Maven that is installed is 3.0.5 if the following command

sudo apt-get install maven

is run.

Instructions for how to install Maven manually can be found here and archived versions of Maven 3 can be downloaded here.
