Plugins break on snap update

[davidjmemmett]

Usually after an Eclipse Snap update, the plugins (PyDev/etc) re-install themselves. This time, they haven't, and after installing PyDev, the plugins won't activate, leaving me with the message No editor descriptor for id org.python.pydev.editor.PythonEditor for existing editor tabs, and opening a new tab for Python files loads a basic editor with colour-coding but no code completion.

Running sudo snap revert eclipse makes everything work again.

Does snap run eclipse -clean resolve it with the current version?

[davidjmemmett]

Do you have a link to any documentation on what snap run ... -clean does? I wouldn't want to run it if it wiped my previous (working) snap environment from working as it's painful having to re-install all the plugins every time.

[davidjmemmett]

(I have done my due diligence, but I can't find any documentation online, on the manpage, or via --help)

It doesn't I'm afraid

[Mailaender]

I think it is the same problem as flathub/org.eclipse.Java#12. As a workaround try deleting https://snapcraft.io/docs/data-locations#p-94053-user-data for the Eclipse snap.
