Eclipse
1) Download and install Eclipse IDE for Enterprise Java and Web Developers (Eclipse IDE 2022‑12), e.g., from eclipse.org/downloads using the Eclipse Installer
2) Create UniTime project
If you plan to make changes, you should consider forking the UniTime project first. See Fork A Repo for more details.
File > Import, select Git > Project from Git, Next
Select "Clone URI" and click Next
Use "Existing local repository" if you already have the UniTime project cloned somewhere, e.g., using the GitHub Desktop app or the git command line tool
Enter "https://github.com/UniTime/unitime.git" as URI; the rest should auto-populate from the URL, click Next
Or, you can use "git@github.com:UniTime/unitime.git" as URI and generate an SSH key (see Generating SSH keys for more details)
If you have forked the unitime repository, the URI will be different
Click Deselect All and select the master and the maintenance branches you want/need (if any).
Click Next
Once cloned, hit Next (import existing Eclipse projects) and Finish
