Check the image, whenever I start Eclipse on my Macbook M1 the app icon gets that red error badge in Dock after the software performs initial startup and deferred early start checks.
Does anyone know how to fix this? I can't stand that error message.
In Eclipse, open Preferences and navigate to General → Workspace. Disable the "Show workspace name" option; this will remove it from the window title, as you would expect, but also from the Dock icon.
