I use Eclipse Swt For my java Applications since Many years on Windows and since 4 years on Raspberry pi Model 4B successfully.

I world like to update to: Raspberry pi Model 5, linux aarch64
I tried the following steps:

Installed Eclipse Java For developers 2024-06
Downloaded corresponding Swt Archive
Imported Swt Archive Into Workspace: a project org.Eclipse.Swt ist generate automatically
Created project myproject
Added org.Eclipse.Swt to project dependency : Bild Path -> project (classpath/Module?')
Created a sample Swt Java file
The Widgets are recognized And an import Statement is added on Top of the Java file. However, the Statement Implies an error
" org.Eclipse.Widgets.Display is Not accessibile"

Any suggestions?

Which Java version are you targeting? Did you inadvertently pick one that defaults to being modular by adding a module-info.java for you?

I want to uninstall everything that is now installed on my Linux computer without effecting the new install of Eclipse since I want to start from scratch. What is the process to accomplish this?

Delete the installation folder, the workspace folder, and probably everything in ~/.p2 and ~/.eclipse.

The problem is resolved.
Just take the corresponding SWT.jar and delete the two files ECLIPSE_.RSA and ECLIPSE_.SF in the directory META-INF using e.g. xarchiver.
The resulting SWT.jar works
