Build Identifier: 20100917-0705 I have my Eclipse workspace folder on a Windows Partition "D:". In the same partition there is an "opt" directory. I reneamed it to see if this directory is required. After next start of Eclipse, a new "opt" driectory was created: D:\Eclipse_workspace\ D:\opt\ The content of this "opt" directory is a serious of subdirectory but with only 1 file: D:\opt\public\technology\epp\epp_build\36\eclipse.S-3.6RC4-201006031500\artifacts.xml It seems that this directory is Eclipse specific. So this should be stored within the eclipse installation directory, the eclipse workspace directory or at least in a directory that is configurable. Reproducible: Always Steps to Reproduce: 1. Start Eclipse on Windows (XP) with a workspace on a separate partition. 2. 3.
Which Eclipse download did you get from eclipse.org? What is the file's name?
eclipse-java-helios-win32.zip
(In reply to comment #2) > eclipse-java-helios-win32.zip Do you get this problem with the Eclipse SDK? http://download.eclipse.org/eclipse/downloads/drops/R-3.6.1-201009090800/index.php
Nope, with eclipse-SDK-3.6.1-win32.zip the opt directory is not created (with the same workspace). But at startup, there is the same NullPointerException: --------------------------- !ENTRY org.eclipse.core.jobs 4 2 2010-10-05 09:40:20.778 !MESSAGE An internal error occurred during: "Refreshing external folders". !STACK 0 java.lang.NullPointerException at org.eclipse.jdt.internal.core.ExternalFoldersManager$RefreshJob.run(ExternalFoldersManager.java:387) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:54) ---------------------------- See bug 326517.
Oh Great: this test destroyed my working eclipse! I just started eclipse-SDK-3.6.1-win32.zip to see if the opt directory is created. Then I closed this eclipse and started my normal eclipse: now several Java projects are missing in the package explorer!!! And the FindBugs perspective shows errors about missing view.

I hope I can recreate all my projects ...
Oh man, this gets worse: I try to get my projects back, but I can't: they are not hidden and when I create a new project I get: A project with that name already exists in the workspace. HELP!!!
(In reply to comment #5) > now several Java projects > are missing in the package explorer!!! Are your projects missing from the 'Navigator' view? > And the FindBugs perspective shows > errors about missing view. ARGGGHHH!!! :-(((( The SDK doesn't include the FindBugs plug-in. So unless you installed it, those views aren't going to come up of course.

*Phew* I got it back working: I opened the "Project Explorere" and it contained all projects. The I select a project that was missing in the Package Explorer and clicked context menu > Show In > Explorer a request dialog appeared but I forget the text it displayed (something with "... change to windows display ..."), accepted with "Okay" and the missing projects reappeared int he package explorer. I wonder how this could happen as this never happened so far when I donwloaded and installed new Eclipse versions and startet the new version with the old workspace. I guess, I have to make a backup of my workspace everytime I change the Eclipse version ... but my workspace is over 350 MB ... But strange: after I got back to my former Eclipse version, the opt directory ist not generated anymore (so far ...)!?! Is this opt directory just generated when specific events in Eclipse occur?

(In reply to comment #9) > context menu > Show In > Explorer > > a request dialog appeared but I forget the text it displayed (something with > "... change to windows display ..."), accepted with "Okay" and the missing > projects reappeared int he package explorer. That means your package explorer was probably set to use a working set, and not the window working set. The Show In was asking if you want to switch back to the window working set. PW
It's not the folder above the workspace, rather the drive the workspace is contained in. So [X]:\opt Some of my users over at PortableApps.com reported the bug. The problem only started occurring after they updated to Eclipse 3.6.1 http://portableapps.com/node/22236#comment-159090
+1 I have C:\eclipse36-64 and now I also have: "C:\opt\public\technology\epp\epp_build\36\eclipse.S-3.6RC4-201006031500\artifacts.xml"

well, the opt folder was dated from months back, and I might have ran some RC over the lifetime of 3.6 development, but as it stands now I run a 3.6 install that just a few days ago I software-updated to 3.6.1. One of my developers was talking to me about the "opt" directory bug (and usually they don't run any RC and recently upgraded to 3.6.1 at my direction), which made me look for, find this bug and just +1 it. If you think this isn't an issue in release downloads then you may ignore me. I'll ping back if I ever see it again now that I am done with RC versions for a while.
