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

        When I try to import the ECF source code using the .psf file
        in org.eclipse.ecf.releng.projectSet-anonymous.psf, I get the
        error recorded in the attached Eclipse log file
        "Ecf-source.log. If, after,  I do Project->Clean to clean the
        workspace and rebuild the workspace, I get the errors shown in
        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.
