Description Dan Campers

2005-06-15 09:54:53 EDT

I have a problem that has appeared just recently, that I think was about the 
time I started using RC1 (previously on M7). I have just done a clean install of 
RC2 and made a new project, so there is no other residue from other plugins, and 
made a test project. I have stripped out most of my code and can still reproduce 
the problem.

The problem is that I can do a trivial modification, like adding a space in a 
comment, and saving the java file, then eclipse can't find an existing class 
(test.Position), that is for one of my source files. In one case (see the test.
TestProjectBuildErrors class), if I enter another space and save, then eclipse 
finds it again.

If I make a trivial modification in another particular class, eclipse cant find 
that class file again (test.Position), and then the only way to get eclipse to 
'find' it again it to clean the project and do a rebuild (eg make a modification 
in test.Portfolio)

Created attachment 23190 [details]
zip of the eclipse project

Zip of the eclipse project that demonstrates the bug. You will need to add
log4j to the /lib folder and updated the build path.

Sorry I cannot read your zip file... not in standard 2.0 format.

Can you please attach the files individually or use another zip utility.

thanks

Cannot reproduce on the latest but was able to reproduce on RC2.

Please reopen if the problem still exists in your full workspace.
