In Eclipse, I am trying to compare local versions, but it just shows this empty, blue pane. Any suggestions?

I recently upgraded my Eclipse and the workspace stopped working.
So I made a new one, copied all my projects over to it, then imported them.
However, now it shows them as folders instead of the actual packages like it used to:
How can I get the packages back?
Are you sure, you are using the Eclipse perspective Java or Java EE and within one of those perspectives, are using the view Package Explorer ?
Most of the times this happening because the Eclipse view Navigator is used, as show here.
I intalled "eclipse-javase neno" and "eclipse-php neno" with "eclipse installer",and then installed pydev plugin in "eclipse-javase", but when I opened "eclipse-php" ,in the "perspective" "pydev" also showed up ,but error occured when clicking on it.I am wondering if it is possible to seprate the two eclipse versions from influencing each other.
You have to use each installation with its own workspace, because the window layout (including the perspective switch buttons at the top right which are displayed once a perspective has been used) is stored in the .metadata subfolder of the workspace.
If you want to edit a project with different installations/workspaces, import the project via Existing Projects into Workspace without the option Copy the projects into workspace.
Using Eclipse Luna Service Release 2 (4.4.2), C and C++, although this problem relates to C code. Running Eclipse on Win XP.
I'm using a system with 2 projects. The projects are linked by Properties - Project References.
Some references work OK: I can use "open declaration" on a symbol in one project and it immediately jumps to the correct place in the 2nd project where it is defined.
However, occasionally I find a symbol which brings up a dialog box "Open Declaration" listing 2 alternatives, both of which are exactly the same file (by exactly the same path). One of these choices gives the correct result, the other one gives almost the same except that it's a few lines out.
Also, Eclipse (parser) thinks there are some syntax errors where there aren't any.
I've rebuilt the index on both projects, tried referencing both projects to each other and also one way only. I've stopped Eclipse and restarted it.
Any solutions?
In my case, the index was out of sync.
From the top level in the project in Project Explorer, right-click and select Index-Rebuild.
Apparently it just happens every now and then; a colleague of mine encounters it regularly (Linux build).
See info about the indexer on Eclipse help.
Up until today all was well with Eclipse and PyDev. I have not modified Eclipse or installed anything since it was working yesterday.
Now, the PyDev Package Explorer shows no entries. I can see them if I switch to the normal project/navigator view.
If I watch the pydev package explorer and switch in and out I can see something briefly appearing then disappearing.
I've deleted every project, created a new workspace and tried uninstalling and installing pydev, but still the pydev package explorer shows nothing.
All settings are correct and I can run python code, but I'd really like my package explorer back.
Any ideas?
I'm on pydev version 3.7.1.x
Thanks.
Maybe you added a filter or made top level elements working sets and have no working set defined?
I.e.: Ctrl+F10 > top level elements > Projects/Working Sets
or Ctrl+F10 > customize view.
This steps helped me for the same issue:
Ctrl+F10 -> Select Working Set... -> No Working Sets
How can I stop Eclipse (Helios) and m2eclipse plug-in to hide last dotted part of folder names when importing existing maven projects into workspace?
While importing existing maven projects into workspace, that window where I select the root folder for the import, those folder names are truncated. The last dot separated part of the folder name is removed. If I have lot of folders named like "com.acme.project1", "com.acme.project2" and so on, then Eclipse shows only bunch of folders having name "com.acme". I cannot figure out which one is the correct one without opening Windows Explorer and browsing the same location and checking out real names of those folders.
I'm not sure if that is problem with m2eclipse plug-in or if it is problem with Eclipse. I don't remember seeing that problem with previous Eclipse versions.
Can anybody help? This is really annoying me.
Most likely you have Hierarchical package presentation switched on. On your Package Explorer view, on the top right dropdown switch to > Package Presentation > Flat in order to see com.acme.project1 and com.acme.project2 presented the one under the other in the Package Explorer.
