Replace old Eclipse to 2025-3 (clean install windows/Debian)

Assume: you used Eclipse eclipse in tar.gz or zip, not using installer.

In Windows delete this directory

1. c:\Users\[username]/.eclipse
2. [home]\eclipse -> your old eclipse
3. [workspace]\.metadata -> your existing workspace for eclipse
   

In Debian delete this directory

1. [home_user]/.eclipse
2. [home_user]/eclipse -> your old eclipse
3. [home_user]/[workspace]/.metadata -> your existing workspace for eclipse

Extract eclipse-java-2025-03-R-linux-gtk-x86_64.tar.gz and put "eclipse" folder into [home].

Run your eclipse, select your existing workspace and install all software you need e.q. WindowBuilder.

Note: Windows will ask your permission to prevent Defender scan your Eclipse for performance. I recommended to exclude Eclipse.

To open existing project in your existing workspace

1. Import -> General -> Existing Project into Workspace -> Next
2. Point "Select root directory" to your existing project directory.
3. Finish
