Description Darin Wright CLA 2010-05-31 15:23:01 EDT 
3.6 RC3

* I checked org.eclipse.jdt.ui out from CVS
* Applied the patch from bug 313972
* Attempted to export/install jdt.ui into my running SDK
* Got a bunch of API tooling errors during the export, like:

eclipse.buildId=I20100530-0800
java.version=1.6.0_20
java.vendor=Sun Microsystems Inc.
BootLoader constants: OS=win32, ARCH=x86, WS=win32, NL=en_US
Command-line arguments:  -os win32 -ws win32 -arch x86 -data C:\eclipse-dev\dev-3.6-2010

Comment 1 Darin Wright CLA 2010-05-31 15:52:40 EDT 
For some reason, this only happens when exporting & installing. If I just export the bundle, I do not see any errors.
Comment 2 Olivier Thomann CLA 2010-06-03 11:11:53 EDT 
I cannot reproduce.
Comment 3 Olivier Thomann CLA 2010-06-03 11:14:18 EDT 
Removing target milestone until I can reproduce it reliably.
Comment 4 Darin Wright CLA 2010-06-03 12:28:05 EDT 
I discovered that this only happens when the option to "Use class files compiled in the workspace" is checked on the export options. When PDE build goes to generate the API description it points to an output location of class files that is empty, and API tooling can't resolve any of the types that the description needs to be generated for.
Comment 5 Darin Wright CLA 2010-06-03 12:34:08 EDT 
For example, the API description generation task is set up with a binary location that points to "C:/eclipse-dev/dev-3.6-2010/.metadata/.plugins/org.eclipse.pde.core/temp/destination/plugins/org.eclipse.jdt.ui_3.6.0.201006031129/@dot". However, that location contains no class files (just package directories that are empty).

Not sure if PDE build can pass in the workspace location when it knows it's using workspace class files?
Comment 6 Olivier Thomann CLA 2010-06-03 12:37:22 EDT 
Moving to PDE/Build.
The ant task expects to be able to find .class files.
Comment 7 Olivier Thomann CLA 2010-06-03 12:53:20 EDT 
It works fine when simply exporting the bundle. It fails only when exporting and installing into host the bundle and using existing class files.
Looking at the build script, I don't understand why the api description file generator is getting an empty container only in the second case.

patch

currently testing this

btw, Darin, I like the "Support software installation in the launched application" for selfhosting, I didn't know that was there.
