Eclipse will no longer open

[aaiezza]

I used the PlantUML plugin several times in my IDE before and it has worked very well. I have restarted Eclipse and my machine several times as well.

Now in the last session I had in Eclipse, I needed to do some designing and leveraged the PlantUML diagram view while editing a .puml file.

It might be important to note I had the view in a separate window from my main eclipse window. From the PlantUML diagram view, I attempted to export the diagram as a png, and my eclipse crashed. Since then, no matter what I have tried, I cannot restart Eclipse.

This is a massive issue! It has essentially halted my development for the day.

Even installing a new version of Eclipse failed to work! It’s like my box has been permanently disabled to Eclipse.

Please figure this out.

I'm sorry to hear about such severe problems. It is difficult to imagine what has happened and even more difficult to diagnose it without access to your machine. Doesn't the new Eclipse you installed work at all, or is it the workspace that cannot be opened?

Hey @hallvard. I could probably edit my issue description. In the moment, I was obviously very frustrated. It turns out that macOS needed a minor update, and when I restarted my computer all of my eclipse instances worked again. That workspace was still broken however. So I ended up making a fresh workspace and then switching back to the other workspace and it miraculously worked again.

I did need to uninstall the PlantUML plugin and reinstall it to get the plugin to work again. After that, exporting the image worked as expected perfectly.

This issue can probably be closed. I no longer think it had anything to do with the plugin.

If someone else has this problem though, maybe it’s good that it is documented here.
