jdk9-jigsaw

Examples of some of the features of Jigsaw released in the Early Access build of JDK9.

Many of the examples here are directly from the Project Jigsaw: Module System Quick-Start Guide, see http://openjdk.java.net/projects/jigsaw/quick-start but we have also contributions from the Java community.

Please note you are in the master branch which contains exercises which need to be solved by looking at documentation or resources provided in this repo. Hints may be provided within the source or script files. If you hit a roadblock and really want to see a possible solution you can switch to the exercise-solutions branch for that.

Looking at the solutions can take away the challenge behind solving the exercises. Stay on the master branch in case you would like to continue to have fun solving the exercises and working through the challenges.

Setup (all platforms)

See Download, install and verify JDK.

Download and install git or git-bash

  • Ensure you have a git client installed on your local machine/VM/vagrant box, for Windows users git-bash is recommended

Download and install the tree and wget command

Please install the tree command before moving forward:

  • Linux

    sudo apt-get install tree
sudo apt-get install wget

  • MacOSX

    install tree - http://apple.stackexchange.com/questions/128876/whats-the-equivalent-of-the-unix-tree-command-on-osx
install wget - http://stackoverflow.com/questions/4572153/os-x-equivalent-of-linuxs-wget

  • Windows

    install `git-bash` (recommended) or `cgywin`

    The tree command is built into Windows. From within git-bash or cygwin. In case a script is invoking the tree command and failing, please replace the tree -fl keywords with cmd //c "tree /f /a". If that does not work either use ls -R instead, except you won't see the output in a tree format.

    Or manually convert the .sh files into .bat, with minor tweaks should also work there.

    Thanks Richard Kolb (@rjdkolb) for your continued support in this area.

Vagrant box

(Optional) Install JDK 9 compliant IDE

  • Install the latest IDE (IntelliJ, Eclipse, NetBeans - paid or community version) that supports JDK 9 EA, once installed configure the IDE to pickup the JDK 9 EA installed in the previous steps.

Other preparations

  • Get familiar with the command-line a bit as we will be using much of it during the weekend

  • Prepare your VMs or cloud instances with the above, in case your local machine is not up for any installation or configurations

Note: the bash files provided should work on Linux and in theory on the MacOS as well.

For Windows users, if you use git-bash (recommended) or cgywin they should work for you.

In the worst case scenario, we would have to manually convert the .sh files into .bat, with minor tweaks should also work there. Happy to received a pull request for it.

Examples covered

Each example is enclosed in a folder of its own containing bash scripts to compile, package and run the respective examples. Use these scripts for each of the examples.
