Eclipse 2022_12_R Installation (Spring 2024)
Overview
In the past it was necessary to install java and Eclipse, but the Eclipse installer
now includes all the tools (compiler, jvm, javadoc, etc.) you need. To have
all the environment you need for CMSC131/CMSC132, you will use the Eclipse
installer and add a submission plugin. Information for PCs and Macs is provided
below. If you have a linux system an installer is also available on the Eclipse installer's
site (see Software Sources below).
Note: This Eclipse version creates by default a module-info.java file when
creating a project. When creating a project, uncheck the "Create module-info.java file"
option you will see under the "Module" section.
For PCs
- Download the Eclipse installer Windows x86_64 available in the blue box with
the title "Try the Eclipse Installer 2022‑12 R" you will
see at
https://www.eclipse.org/downloads/packages/release/2022-12/r.
- The file you download must have the .exe extension, otherwise you have the wrong file.
- Double-click on the downloaded file.
- Eventually you will see a list of Eclipse IDE options; select
"Eclipse IDE for Java Developers."
- You will see Java 17 + VM (please do not change the default you will see to the right).
We need to use Java 17 as the submit server relies on it.
- Once the installation is complete, your will see a shortcut to Eclipse on your desktop.
- Launch Eclipse and make sure you specify a Workspace (directory) that has not been
used with another Eclipse version; this is to prevent any conflicts.
- Install the Course Management Plugin Installation as
described below. If you don't install this plugin, you will not see the
"Submit Project" button that will allow you to submit projects from Eclipse.
- Eclipse does not come with an uninstaller. Deleting the application is enough to
uninstall it.
For Macs
