Introduction to Java

This is the support project for the "Intro to Java" course at ReDI School.

The website is visible at:

https://redi-school.github.io/intro-java

This website was generated from the course-template. You can create your own course website creating a repository out of the same template.

Authoring the website

Every markdown .md file is scanned and transformed into a page automatically. This includes files in subdirectories. The course homepage is stored in index.md.

The website is built using Jekyll and hosted automatically by GitHub Pages. You cannot use a different generator, as Jekyll is the only one supported by GitHub Pages.

For details on how to author a static website using Jekyll, please see the Jekyll documentation.

How to publish and update the course website

This website is built by GitHub Pages using Jekyll. This happens automatically if GitHub Pages is configured in the following way:

• Go to the settings of the project
• Enable GitHub Pages
• Configure GitHub Pages to publish directly the master branch (not master/docs or gh-pages)
• Don't select a theme

Once these settings are applied to the project, every commit on master will trigger a new build of the website that automatically replaces the older version at the github.io URL above. The URL can't be changed.

Building locally

To build and test the website, you must have a Ruby development environment with Bundler.

Installing Ruby, Bundler, Jekyll

On Ubuntu LTS 20.04:

sudo apt install bundler ruby-dev zlib1g-dev

The last two packages are needed to compile some native Ruby dependencies (Ubuntu specific). On MacOS and Windows, please follow the installation instructions of Ruby and Bundler as suggested in the Jekyll install guide.

Once Ruby and Bundler are installed, use the following command to download the gems, including the proper version of Jekyll (only once):

bundle install --path vendor/bundle

This creates the .bundle and vendor directories, that should not be committed to the git repository.

Building and testing the website

To build, test and serve the website locally, please run:

bundle exec jekyll serve

You can then visit the website on localhost:4000.

About the ReDI theme

Note this website uses Just The Docs, a well-known Jekyll theme, customized with ReDI colors and logos.

For instuctions and examples of what the theme can do, and how you can do the same in your course pages, please see:
