Note for Linux Users

If you are running a linux machine Javafx is not included in the openjre package
For Debian systems you can download it with

sudo apt install openjfx

Dependencies and Usage

• Java 9 or greater is required for to run this project. For assisstance in installing Java 9 refer to this page on oracle.

  • Due to the fact Java 10 is the last remaining version of Java before the removal of javafx, any later version will require openjfx.

• (optional) A makefile is provided to compile this project. To download make refer to this link if you are on windows. Linux users can simply run the command sudo apt install build-essential (command may vary per distros)

• Usage using make

  • cd to the top level directory
  • run make
  • after make has finished use the command java -jar out/STEM.jar

• Usage without using make

  • cd to the top level directory
  • run javac -encoding utf8 -d out/classes src/*.java
  • run jar cvfm out/STEM.jar src/META-INF/MANIFEST.MF -C out/classes/ . -C src/ checkmark.png
  • After this has finished use the command java -jar out/STEM.jar

• Easiest Usage

  • Download the javafx SDK from JavaFx Gluon and install where ever you wish
  • Make sure your JRE is JRE version 10 or higher.
  • Make a shell script file, with the contents that are below.
    • Change the path variables to where your JRE/JavaFXSDK are located. The paths that are in the example are what's used for running the program on the Hydra machines.
  • run source openjfx.sh or whatever you name the shell script
  • Then run the program by executing javafx STEM.jar
  • If you are doing this on Windows: it is better to use a Linux subsystem, such as Git Bash.
  • If you are running this on the University of Tennessee's Hydra/Tesla machines, simply writing this script, sourcing it, and executing should work.

# Shell script for linking and running STEM.jar. The paths are set for what's on the Tesla/Hydra machines. 
#   You will need to update these paths if you're running it on your own machine. 

# path to the JRE - Update to where java is installed on your machine
export JAVA_HOME=/usr/lib/jvm/jre-14

# path to the javafx SDK. Update to where it is installed on your machine
export JAVAFX_HOME=/opt/eecs/javafx-sdk-11.0.2

# update the path
export PATH=$JAVA_HOME/bin:$PATH

export CLASSPATH=$JAVA_HOME/jre/lib/:$JAVAFX_HOME/lib

# make an alias for running the program
alias javafx="$JAVA_HOME/bin/java --module-path $JAVAFX_HOME/lib --add-modules javafx.controls -jar"
