A recent I-build recently failed with a msg such as below. I'm not sure, but one hypothesis is that the required jar was just deleted out from under the build job by the routine "clean up" job. That is, it was being too agressive (or, more precisely, using the wrong thing to "measure". It is supposed to only remove things if "older than 14 days" ... but, might have been using one of the higher directories time stamps? = = = = = 167093 [build-wtp-wst-sdk] /shared/webtools/projectBuilders/wtp-R3.3.0-I/webtools.releng/releng.wtpbuilder/scripts/build/buildutilitiesp2.xml:89: java.io.FileNotFoundExcepti on: /shared/webtools/tmp/tempupdatepackproperties/temp-I-3.3.0-20110307204516-wst-sdk/features/org.eclipse.wst.common.fproj.sdk_3.3.0.v201102150115-787IFBVApOGQPIOLGH YNY785BBB.jar (No such file or directory)
It appears they are not "deleted too soon" (as I originally thought) but never created (unzipped) there to begin with. Probable reason is related to updating our "tools" to include new ant-to-php task and, I suspect, I introduced some changed in "update pack properties" task that were in head, but never used/released. In the worst case, I could revert tools level ... but will try a few runs to push through and fix issue.
As far as I can tell ... when having previous problems ... long ago ... deleting files from build.eclipse.org file system (which uses NFS), I added some code to not create empty directories from zip file entries. (It didn't seem to help the could-no-delete problems on build machine ... but...) I thought I'd released and had been using that, but apparently I was confused ... long ago ... and that code has not been in fact been running. So, when I updated for the ant-to-php task, the version of updatePackProperties task got updated also to not create empty directories. The problem, I think, is that directories such as "features" and "plugins" come across first as empty directories, and if they are not created, other file creation operations fail silently .. as far as I can tell. In any case, it's working now, happily creating empty directories, and still not able to delete them (immediately). But, we can sign again. [FWIW, this wasn't noticed on test builds of the ant-to-php task, since we don't sign on test build machines, so that updated code for updatePackProperties was never ran on test machine.]
