Comment 2 Gary Benson 2005-05-25 11:38:45 UTC 
Ok, the problem is that /usr/share/java/jdtcore.jar was renamed as
org.eclipse.jdt.core_3.1.0.jar between eclipse-ecj-3.1.0_fc-0.M6.22 and M7.5. 
As an immediate fix I'm going to patch java-gcj-compat's tools.jar to use the
new path (Beehive will be broken until we do this) but for the long term we
should probably do something more robust: a filename like
org.eclipse.jdt.core_3.1.0.jar is obviously not something that's going to stay
the same over time.

How about having having the /usr/share/java symlink called eclipse-ecj.jar?
jdtcore.jar is fairly undescriptive for such a crucial file.
Comment 3 Andrew Overholt 2005-05-25 12:47:38 UTC 
Sorry I didn't notice this change when we pushed in Eclipse 3.1M7. 
eclipse-ecj.jar sounds good to me; I'll make that change now.
Comment 4 Gary Benson 2005-05-25 13:28:12 UTC 
java-1.4.2-gcj-compat-1.4.2.0-40jpp_25rh in dist-fc4-HEAD is pointing at
org.eclipse.jdt.core_3.1.0.jar, so ant in beehive will start working again when
someone moves that across to dist-fc4.  If you build a new eclipse for FC4 then
could you please make sure java-gcj-compat is updated and rebuilt too?  The bit
that needs changing is in java-gcj-compat-bz158734.patch for now.
Comment 5 Thomas Fitzsimmons 2005-05-25 16:00:16 UTC 
This is fixed in java-1.4.2-gcj-compat-1.4.2.0-40jpp_26rh.
Comment 6 Gary Benson 2005-05-25 16:23:05 UTC 
Woah, Andrew hasn't changed it in eclipse yet!
Comment 7 Thomas Fitzsimmons 2005-05-25 17:58:15 UTC 
The updated eclipse is building right now.
