Our illustrious PHB decided that the project name was wrong. So I went
through the I18N files and renamed as required. I changed the
application configuration files.
The final step was to rename the project within Ecplise.
So.
RMB on the project name (at the top of the tree), choose
refacter/rename, typed in the new name. Update references was checked.
After about 1 1/2 hours, I killed the java process (WinXP). This caused
the RAM usage to climb to 5.1Gbytes (yes, that IS a G) before eclipse
finally shut down (with a JVM death warning message).
Restarted the computer as some phantom process was still holding over
1.5Gbytes.
Went to start Eclipse. Got a warning that the old project was not found.
Fair enough. I shut down all the editors, then went to open the project.
The old project name was in the project list. In the directory
structure, in the workspace directory, the new project name is there. In
its .project file, the new project name is there.
Re-started Eclipse with -clean. Same problem.
So:
- why did this fail?
- where does Eclipse store which projects are in the workspace, so I can
rename the project, so Eclipse can "see" it (did a search, no joy)
- barring all else, how do I recover from this?
/ dead in the water :-(

Then wouldn?t it be wiser to (copy outside Eclipse and) delete the new
project, and retry the renaming? Could have been a red herring.

What do you mean, that the old project is still there, or that the new
project has the old name?

After 1 1/2 hours? Why would it complete the second time if it did not
complete the first time?
>>BUT, I still have the old project name showing. How do I delete it?

The original name is ProjectA.
In Ecplise, when opening projects, the list of projects shows ProjectA.
I renamed it to ProjectB. After a long time I killed the process.
On the hard drive, the directory in the workspace shows ProjectB.
In Ecplise the list of projects shows ProjectA.
I imported ProjectB (from the workspace).
The list of projects shows both ProjectA and ProjectB, even though
ProjectA does not exist, and cannot (of course) be opened.
So what do I edit to remove the reference to the non-existant ProjectA?

I do not know, but I suppose we both know that software does not always
behave the same. Far too many if statements around for that :-)

You killed it in a non-friendly way? Then I am not very surprised:
Eclipse always needs some time at shutdown to write its configuration.
If it didn?t get the chance, this might be one of the things that didn?t
get written down properly.
> On the hard drive, the directory in the workspace shows ProjectB.
Indeed: the renaming occurred, but some xml properties file describing
the projects in the workspace wasn?t updated.

After restart, I suppose?

I would first make a backup of ProjectB (outside Eclipse), then try to
delete ProjectA (inside Eclipse). If that still doesn?t work, you can
try to delete ProjectB (inside E) too, and look if it is possible to
remove ProjectA now. If ok, then re-import ProjectB from the backup.
If this still didn?t work, look for the properties file in the .metadata
directory which holds the list of projects, and, after backup of course,
edit/remove it. (With Eclipse shut down).
There are some more options, but try this out first.

Yes I know :-)
But there was no movement on the progress bar, the RAM usage was not
changing, it was not using any CPU time, and I had finished lunch.
It certainly appeared frozen.
On a side note (just thought of it) I have a rather large history set
(30+Mbytes). It may be that Eclipse was parsing the entire history set
doing the rename. But, there was not visible activity. If any Eclipse
devs are lurking, maybe you could add a detail button showing each file
being processed?

Which is my guess. Doing searches on the hard drive (Eclipse install
directory tree and workspace directory tree) for files containing the
old project name comes up empty. I also did a Registry search.

Yes well, but how do I delete it?
The usual path is to open the project, RMB on the name, the choose delete.
I cannot open the project. Th error is that the old project name has an
invalid .properties files. Which is correct as it does not exist any more.

A closed project can still be deleted. Right-click on it and choose Delete.
Hopefully, that will work. If it gives you an error (it might because
the project's directories/files don't exist any more), then you can shut
down Eclipse and look in the
..metadata\.plugins\org.eclipse.core.resources\.projects directory of
your workspace to see if there is any residual junk related to the old
project.
Hope this helps,
Eric

It wasn?t meant accusatory, just an observation that could lead to the
solution.

So there is no empty folder with the name ProjectA? Otherwise, you
could just delete it.
What does ProjectB?s .project file say?

Then maybe you could create one. Create an empty folder ProjectA in
your workspace, copy ProjectB?s .project file into it, and change the
necessary names. Maybe then it will be possible to open the project and
delete it?

Interesting.
I closed the current project.
I then RMB in the Package Explorer and clicked on Refresh. Got a warning
message the the old project did not exist, did I want to delete the
reference. Clicked on Yes, and now the old project is gone.
I am still curious just where the reference was stored.
Anyway, thanks for the help (both of you) :-)
