Re: [cross-project-issues-dev] org.eclipse.equinox.p2 Permission denied

There may be several problems preventing your access, but the usual advise is to put "tmp" in your ${WORKSPACE} ... that is the Hudson workspace ... so that way, it is "yours" to cleanup, etc., as you like.

You do have to create the directory first before Java will use it, perhaps even as a separate build step (depending on how you do your build) ... mkdir -p ${WORKSPACE}/tmp

And then, everywhere that Java might be invoked, use${WORKSPACE}/tmp ... that'd be for direct calls to Java, of course, but also Ant, Maven, and/or Eclipse itself, as they will eventually call Java.

Dear all,

I've created a new Mars build job (eatop-0.5-mars) for EATOP project on hudson server ( recently, and I got the following errors ( while building:

!ENTRY org.eclipse.equinox.preferences 4 4 2014-09-12 19:10:46.197
!MESSAGE Exception saving preferences to: /tmp/p2/org.eclipse.equinox.p2.engine/.settings/org.eclipse.equinox.p2.metadata.repository.prefs.
!STACK 0 /tmp/p2/org.eclipse.equinox.p2.engine/.settings/org.eclipse.equinox.p2.metadata.repository.prefs.bak (Permission denied)

It appears that /tmp/p2(and it's children) is owned by a different hipp user and group(Modeling ECP), so when my job runs (as the EATOP user) it's unable to write in that directory.  
Does anyone know how to specify a different directory (e.g., /tmp/eatop/p2) that will probably get things rolling? Thanks for any help in advance,

Best regards,
