Eclipse Indigo: how do I uninstall a plugin if the Help -> About Eclipse SDK dialog won't display?

Question

Scala-IDE is messing up my Help -> About Eclipse SDK dialog, so the obvious method of uninstalling is not working. (as mentioned in this other question)

How can I uninstall it?

Solution 1

'Eclipse Marketplace > Installed > Uninstall' sometimes works as well.

Also, from How do I remove a plug-in?

To physically remove the feature and its plug-ins, you will have to manually remove the feature from the eclipse/features directory and its plug-ins from the eclipse/plugins directory.

Solution 2

On Eclipse Indigo ...

1. Click on Help > About Eclipse
2. Click on the "Installation Details" button
3. Select all the installed software you want to uninstall
4. Click "Uninstall ..."

Not sure why they have "hidden" this in the "About Eclipse" section.

Solution 3

Help -> Install New Software ....

In the "Available Software" dialog that opens, there is a tiny link towards the bottom labelled "already installed". Click on that, and it's another route to getting to the uninstall bit.

Not exactly intuitive, but it got me around this problem

Please read my question fully. I cannot access the About Eclipse dialog, therefore I cannot follow the usual method.

I tried this, but my "Uninstall" button (in Indigo) is disabled for anything installed. Very frustrating.
