Comment: Remove Gradle 7 references

Fully hand-held tutorial on setting up the Java environment to a usable state as quickly as possible. Only knowledge of using the terminal is expected. This tutorial will be completely self-contained (excluding links to downloads).

This guide contains some links to some internal pages; these links are not necessary for setting up the environment and only exist as additional assistance for IHMC personnel and others with access.

This will download Java to the folder (or as appropriate for the version)

Code Block
C:\Program Files\Java\jdk-17.0.3.1
  • (Aside: The java path variable is already set using oracle. No action is needed)
  • Double-check that java is installed properly:

Open a terminal and type in:

Code Block
java -version

Something like the following should be outputted:

Code Block

    Excerpt
    • Create a new directory C:\Gradle with File Explorer.
    • Open a second File Explorer window and go to the directory where the Gradle distribution was downloaded. Double-click the ZIP archive to expose the content. Drag the content folder gradle-7X.4X.2 Xto your newly created C:\Gradle folder.

  • Add to path

Import Repositories

Quick:

Multiexcerpt
MultiExcerptNameclone command line

We will be cloning repositories from the command line. 

Open a terminal and cd to a directory where you want to hold your files. The directory is arbitrary, but you will need to remember it.

First, consider a name for your repository group. "repos" works if you only need one workspace. That name will referred to as <repo-name> below.

Run the following:

Your folder structure should now match what is shown in the next section.
