Eclipse: Project 'PROJECT_NAME' has no explicit encoding set

Question

I downgraded from Windows 11 to WIndows 10 today and had to reinstall the Eclipse-IDE. After successfully importing my workspaces and fixing the projects, a warning appeared for every project saying "Project XXX has no explicit encoding set". I've already searched for a solution and only got some fixes for VSCode.

I had Eclipse 2021-6 and installed Eclipse 2022-6

Yes, the warning for projects with no explicit default encoding is a new thing in Eclipse 2022-06 (4.24).

To set an explicit default encoding do one of the following:

In the Problems view, select the warning, hit Ctrl+1 and apply the provided Quick Fix (sets the project encoding explicitly to the workspace encoding)
Change the project manually in Project > Properties: Resource
