Re: [ecf-dev] Importing Ecf source code using Project Set file
|
Hi Jonathan,
I think your analysis is right wrt timing. In my opinion, this would
constitute a bug in JDT, PDE, and/or core resources (I'm not certain where).
Please consider reporting these problems to one or more of those
projects (and attaching logs). I would start with jdt and the platform:
https://bugs.eclipse.org/bugs/
Sorry this affected your experience with importing ECF's project set.

I believe that there may be timing and/or dependency problems. If you
try downloading several times, each time into an empty workspace, you
will get errors every time, but not necessarily the same errors on the
same projects. If you do a clean/build procedure after downloading,
initially you will see errors in the error log, but eventually
(mostly) Eclipse will report that all projects are OK.
My machine is a dual-core machine so there is ample opportunity for
exposure to various synchronization problems.
Some of the problems seem to be dependency problems where dependency
prerequisites have not yet been built but others such as the problems
deleting files from bin directories look like synchronization problems.
When importing using the .psf file, as I understand it, the projects
are processed by the builder after downloading in the order they
appear in the .psf file. This suggests the possibility that the .psf
export process generated a bad dependency order. However, errors
during a clean build suggest that the Java builder process may also be
generating dependency problems.

Hi Jonathan,
I looked at your log, and unfortunately I'm not quite sure what is
going wrong. There seem to be a number of errors with
core.resources that look like this (with different resource names):
!MESSAGE Problems encountered while deleting resources.
!SUBENTRY 2 org.eclipse.core.resources 4 273 2010-04-25 12:29:55.711
!MESSAGE Could not delete '/org.eclipse.ecf.discovery/bin/org'.
<stack trace>
These errors are occurring on ecf project and on emf projects.
I don't immediately understand why this would be happening...as it
should be possible for any project in the workspace to have it's
bin directories deleted (by the java/plugin project builder). It
could be something new wrong with the Eclipse 3.6M6 resources
system (i.e. regression)...but I'm not sure about that. It
doesn't look to me like anything wrong specifically with our
project set file or projects.
In the past, I've had success by using a new and empty workspace
to import to...and then after importing sometimes repeatedly
cleaning/building all projects (sometimes more than once).
If anyone else has seen errors like these that Jonathan is seeing
and knows what's causing it please speak up.
Thanks,
Scott

the Eclipse log file "ECF-source2.log".
I am running Eclipse 3.6 M6 using the RCP/RAP 32 bit package
as my base. I use the Sun JDK 1.6.0_20 (32 bit) and I am
running on Windows 7 Professional 64 bit.
I am prepared to try to dig into this problem, but I may need
a little guidance getting started as I am not familiar with
the innards of the Eclipse Java build process.
