Description john prieur CLA 2008-09-09 09:15:29 EDT
Build ID: I20080617-2000

Steps To Reproduce:
1. install Crystal Reports for Eclipse plugin via the update manager, (a plugin for example).
2. create, close, re-open the Crystal Reports project; visit various files.
3. do step 2 a number of times because this problem is intermittent.
4. suddenly, eclipse can't see javax and other libraries.
5. verify, all the libs are intact and still defined.
6. try making a small edit and then Clean. problem remains unfixed.

More information:
Note: seems like bug in eclipse 3.3 # 183117 but emerges for different reason and the work-around doesn't work (step #6). 

Note: doing a Project> Clean does not work-around the problem as
 suggested bug 183117.  
The only choice is to totally reinstall eclipse3.4 .

Note To install Crystal Reports for Eclipse, use the eclipse update manager. Instructions are at...

Can you please follow the instruction from bug 183117 comment 4 and attach the resulting trace to this bug?

Created attachment 112309 [details]
traced the moment of loss of User Libs - MSWord w/screenshots

1. Created a Crystal Reports-plug-in project  MyCrE24e.  not in trace mode by the way.
2. observed that user libs are visible.  (screen capture included.)
No java errors in sample source code created by Crystal Reports-for-eclipse plugin.
3. closed eclipse and restarted it in trace mode.
4. opened the project.
5 observed that user libs are not visible.  See trace and screen capture.

Continuing to try to reproduct the bug as I normally get it:
i.e. not just when starting eclipse but at some random point during normal use of files in the project.

In this document, you say: 
  "2. observed that user libs are visible.
  User Libraries were visible to eclipse3.4"
then a screenshot shows the build path of the project. 
However it doesn't show the user libraries page (as the next screenshot does).

Also the trace is not readable as lines are wrapped. Could you please make sure that the DOS window's buffer size is large enaough, and attach the trace as a text file (without wrapping the lines) ?

There also seem to be a confusion in the terminology. You said:
  "User Libraries (including rt.jar and all the fundamentals) are not visible now…"
but rt.jar is not a user library.

Please clarify (see comment 3)
Comment 5 Mike Wilson CLA 2009-05-05 10:44:40 EDT
Changing Version tag to something more believable.
