Hi Greg, this is not a MercurialEclipse plugin issue...
It is just "usual" learning process for plugin developers, that Eclipse "update/install" framework "p2" is not so nice as it always advertised [1]. You should NEVER install things via GUI and uninstall them manually. This simply doesn't work, because it is not designed this way. If you have used ANY GUI to install the plugin, you should use GUI to uninstall it. If you like to control things to have a predictable state, you have to installe plugins manually (copy) and uninstall them manually too (remove + "-clean" startup afterwards). But you can't mix. 1) In your case, you should NOE manually copy all the deleted jars back to the previous place and uninstall them properly via "update" GUI. 2) Then, features anre not needed for the plugin itself, they are just a tribute to the p2 framework. So if you install your plugins *manually*, you can live fine without features (like me). 3) It is not clear for me, *HOW* you have "installed" your plugin version, so I can't help with this one. My personal way to work is NEVER use GUI, export deployable plugin via File->Export->Deployable Plugins->Directory, then copy the plugin to the Eclipse plugins (3.4) or dropins (3.5) dir, and restart Eclipse with -clean argument. 4) Give Eclipse 3.5 a try - it has much less p2 issues, and more PDT goodies for plugin developers.
