Description alexander korobov CLA 2005-04-06 13:53:06 EDT 
My project's source code and libraries are located on linux build machine 
exported to windows devbox[2000 sp4] via samba. Project has several folders 
that are linked to remote samba folders containing code. 
For some reason Eclipse [3.1M6] looses type information for all code located 
under these folders, but it still keeps type information for classes located in 
zip/jar archives that are also located under lonked folders.
This problem is not reproducible right after creating/importing project but 
rather develops after some time(happened for 3 projects within 1 day).

This problem does not happen when code is located on local disk and addressed 
without using linked folders. I have yet to test whether this problem appears 
in project that uses folders linked to directories on local disk.

Is there any way to debug/trace the way code [re]indexing works?


Thanks a lot.

To debug indexing create/modify .options file in eclipse starting directory by
adding/modifying following lines:
# Turn on debug tracing for org.eclipse.jdt.core plugin
org.eclipse.jdt.core/debug=true

# Reports background indexer activity: indexing, saving index file, index queries
org.eclipse.jdt.core/debug/indexmanager=true

If you're able to reproduce this problem with latest build (at least RC1),
please attach trace you'll get with these options and reopen this bug asap, thx

This problem occured again in 3.1RC1. Here're the conditions:
1. workspace contains 2 projects that refer to 2 copies of the same code, 
meaning almost all class names in both projects are the same(let's say project 
A and project B have the same class SnmpCommunityHook.java)
2. In 'Open Type' i can see two choices of SnmpCommunityHook.java for project A 
and project B.
3. devbox(windows2k) crashed while eclipse was doing refreshing/reindexing or 
one of the projects(project A)
4. once eclipse was restarted it did refresh/reindex again. At this moment it 
does not show in 'Open Type' SnmpCommunityHook.java for project A  but still 
shows SnmpCommunityHook.java that is in project B.
[It's not only one class Foo.java but rather a set of 'affected' classes]

5. SnmpCommunityHook.java actually exists, and can be seen and opened in/via 
Navigator/PackageExplorer.

Refreshing  the whole project does not fix the project, it looks like eclipse 
refresh/indexing does not see such classes in project A. The only thing that 
actually helps is to remove project A and import it again.
 
I attached a screenshot of 'Open Type' dialog.

Unfortunately, I was never able to reproduce this problem
Please reopen if you have steps to reproduce it.
