[pde-build-dev] Headless build cannot resolve classes in org.eclipse.swt.widgets
Hello all,
 
I am making progress with the headless build but am encountering one strange compile error.
Here is the scenario:
 
Start eclipse (3.1.1 Release, CDT 3.0.1 also installed, Win XP) as headless antRunner:
 
java -jar startup.jar -data D:\Projekt\RTP\ws-ant-debug -application org.eclipse.ant.core.AntRunner
-buildfile D:\Projekt\RTP\ws-ant-debug\com.siemens.ad.rtp.build\scripts\build.xml
-Dbuilder=D:\Projekt\RTP\ws-ant-debug\com.siemens.ad.rtp.build\scripts
-DbuildDirectory=D:\Projekt\RTP\ant-export
 
The buildfile and genericTargets.xml were copied unmodified from org.eclipse.pde.build/scripts to the builder directory. Additionally the builder directory contains the attached customTargets.xml and build.properties. I had to do some unusual stuff with the fetch targets because our sources are not stored in CVS. Instead I am copying them from someplace. I don't think this is an issue here.
 
The feature I am building contains two plug-ins, one that we did from scratch, and another from CDT which we are planning to patch. They both get built as desired except that the compiler gives error messages:

The "missing" classes are in the platform-specific fragment org.eclipse.swt.win32.win32.x86_3.1.1.jar which contributes to org.eclipse.swt_3.1.0.jar.
 
I am also attaching manifest and plugin.xml files for these two plug-ins,  neatly packaged in zip-files. Any more info I can supply?
 
Needless to say, the export of "my" plug-ins from the eclipse workbench functions without any problems. It is only in headless mode that there are difficulties.
 
 
Thanks for looking at this,
 
 
Norbert
