There has been a flurry of activity over at Eclipse Bug Report #57897, and things are starting to shape up. The build will now succeed, but there definitely seem to be some missing pieces, as seen in my last comment, #42:

Thanks, the removal of the fetch dependency from the run target of the build.xml
file rectified the previous issue found in comment #42.

When testing the corrected build scripts, I received similar results on the
srcIncluded versions of the Eclipse 3.01 Release, Eclipse 3.1 M2, and Eclipse
Integration 20041013 packages:

Eclipse 3.01 Release and Eclipse 3.1M2 Build:
gather.bin.parts:

children:

rootFileslinux_gtk_ppc:
    [chmod] Skipping fileset for directory /home/barryh/eclipse-3.1M2/tmp/ecli
pse/linux.gtk.ppc/eclipse. It is empty.

init:

gather.bin.parts:

children:

run:

Eclipse 3.1 I20041013 Integration Build:
init:

gather.bin.parts:

children:

rootFileslinux_gtk_ppc:
    [chmod] Skipping fileset for directory /home/barryh/eclipse_I20041013/tmp/
eclipse/linux.gtk.ppc/eclipse. It is empty.

Total time: 96 minutes 1 second

After the build, the linux-gtk-ppc-sdk.zip archive exists is the results
directory as indicated in the installation instructions for all three package
versions.  Upon expanding the archive, the contents appear as follows:

There is no executable named "eclipse" as mentioned in the documentation.  Is
this normal, and if so, how should eclipse be launched in that case?

My apologies for the delay, but testing all three builds took a while with my
test machine.

An incremental pace, but encouraging nonetheless…
