Build notes

CLARA requires the Java 8 JDK.

Ubuntu

Support PPAs:

$ sudo apt-get install software-properties-common

Install Oracle Java 8 from the Web Upd8 PPA:

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

Check the version:

$ java -version
java version "1.8.0_101"
Java(TM) SE Runtime Environment (build 1.8.0_101-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.101-b13, mixed mode)

You may need the following package to set Java 8 as default (see the previous link for more details):

$ sudo apt-get install oracle-java8-set-default

You can also set the default Java version with update-alternatives:

$ sudo update-alternatives --config java

macOS

Install Oracle Java using Homebrew:

$ brew cask install caskroom/versions/java8

Check the version:

$ java -version
java version "1.8.0_92"
Java(TM) SE Runtime Environment (build 1.8.0_92-b14)

   Use
      --project-cache-dir /tmp
   to save artifacts in /tmp
