I recently installed a plugin for a commercial tool. I did this while Eclipse was opened with a C workspace. Since then I cannot get a view of my C project anymore.
All this is with Eclipse Helios on MS-Windows XP.
In the workspace there are a .project and a .cproject, and a .settings dir, that haven't changed in ages. On MS-Windows there is also a .metadata dir which does get updated. Oddly, I also develop the same project on iMac, and there is no .metadata in that environment.
When I remove the .metadata on the MS-Windows and re-start the workspace, then Eclipse opens with the initial welcome and tutorial; a .metadata tree is rebuilt. However in the C/C++ perspective I cannot open or close any project (menu options greyed out), and the project explorer remains completely blank. When I switch to a workspace that is one up in the directory tree, which does contain some directories with Java projects, I do get to see those in the perspective: this parent dir only contains a .metadata; the actual Java dirs contain a .project and a .settings dir.
Does anyone know what I am missing so that I can get to see my C project again in the explorer?
Thanx,
Tom

The .metadata directory is almost certainly being created on the Mac.
What is likely happening is that it is hidden because the name starts
with a '.'. Unix uses this to designate hidden files and folders.

By removing the .metadata directory, you have removed all knowledge of
the project from Eclipse. That is where it stores the information about
what projects are in the workspace. You need to re-add the projects to
Eclipse. It sounds like you have the projects stored in the workspace.
(This the default, but isn't a requirement)
You should be able to use the File->Import wizard to get the projects
back. Open File->Import and select Existing projects into workspace.
From the root directory section, browse to the workspace directory (the
one above the directory that contains the .cproject/.project files).
Eclipse should then find the existing projects and list them in the
Projects window. Select the project and hit Finish.

This sounds a little confusing. Eclipse doesn't support workspace
nesting. You can't have a workspace within another workspace. If this
is really the structure you have, you need to separate the two
workspaces out into separate directory structures so that they don't
overlap.
