Re: [simrel-dev] Fwd: [eclipse-packaging/packages] Eclipse 2025-06 fails

[Erik Brangs <erik.brangs@xxxxxx>]

Hi,

as an end user of Eclipse, I'd prefer 4).

I was using the "Darkest Dark Theme with DevStyle" for a time. It was noticeably darker than the built-in Eclipse themes (black instead of dark gray) and I preferred that. That said, this is not the first time that the DevStyle plugin broke Eclipse. There was an instance where it made all the text in dialogs illegible due to a color mismatch. I was barely able to reset to an older version using the built-in Eclipse dialog for configurations. I think that was in 2024-06. In 2024-09, the Eclipse IDE crashed immediately with the plugin installed (NoSuchMethodError). IIRC I was not able to revert to a working version. I tried using the p2 console to revert but I found it practically unusable for someone not familiar with p2. So I had to reinstall Eclipse IDE. Luckily, I had the preference recorder enabled so I didn't lose any settings. I was merely very, very angry and decided to ditch DevStyle.

I do not see why Eclipse should accommodate a plugin developer that has a history of not adjusting their plugins quickly enough.

In the long term, I would find it helpful if you could create and select new configurations via the command line. You should be able to remove offending plugins without starting the IDE.
