Eclipse 2025_06_R Installation
Overview
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 package Windows x86_64 available
at https://www.eclipse.org/downloads/packages/release/2025-06/r/eclipse-ide-java-developers
The link is underneath the title "Download Links".
- The file you download must have the .zip extension, otherwise you have the wrong file.

- Open the extracted folder, then open the “eclipse” folder, then launch Eclipse by
double clicking “eclipse.exe”. Optional: right click eclipse.exe and click “create shortcut”. You can
put the shortcut wherever is convenient (i.e. your desktop).
- It will ask you to specify a Workspace (directory). Please use or create one that has not been
used with another Eclipse version; this is to prevent any conflicts.

If you don't install this plugin,
you will not see the "Submit Project" button that will allow you to submit projects from Eclipse.
