Target platform not materializing [message #1725152]

Hi,

I am creating a simple Xtext project with the wizard and add the Buckminster build support, also from the wizard, as outlined in http://www.lorenzobettini.it/2012/11/building-xtext-projects-with-buckminster/ and as I did many times before.

The only local change is that we have a local mirror of the eclipse repositories (and no internet access). The problem in this case is that the target platform remains empty, no matter what I do, both when running headless and from the IDE. The 'resolve' command succeeds (bundles are found in the p2 catalog), but then the build fails because the target is empty.

I tried <cq:advisorNode namePattern=".*" useTargetPlatform="false"/> and most of the other values (just to make sure).

This is with Mars and Bucky 1.7.0.

I think i tried all alternatives, to no avail. Either I am missing a silly obvious detail, or something is wrong somewhere...

best regards,
Vlad

Hi

Do you get any specific error/warning during target resolution?

could you please increase the log level just to have an idea of why it
is not resolving anything?

cheers

Hi Lorenzo,

I already run with 'debug' logging and the beginning of it looks like below. It resolves all right, but does not materialize it in the target.

Vlad

Hi

the log does not tell me much, I'm afraid...

The suspicious part is

org.eclipse.platform:eclipse.feature: Rejecting provider local(target):
Target platform disabled in query

org.eclipse.platform:eclipse.feature: Rejecting provider local(target): Target platform disabled in query

I interpreted that as an effect of using

useTargetPlatform="false"

. The bundles are found in the p2 repo, but nothing happens after that.

Thanks anyway. Hopefully someone has some idea about what might be going on.

regards,
Vlad

Hi Vlad,

I can think of two things.
1. Buckminster uses the default target platform for some reason. It will then create a .buckminster directory in your
workspace where all the TP contents that it doesn't find in the current runtime (IDE or Headless) will end up.
2. It uses some other TP.

Did you try starting with an empty workspace? Can you see that it grows (as in consume more disk space)?

Hi Thomas,

Thank you for the suggestions, but I tried changing the target platform in different ways (default and in an own directory) without any result. What happens is that only artifacts.xml is created and it contains <artifacts size="0"/>...

The headless build creates a fresh workspace, so i tried that too. I can't see anything related in there, it is only 15M with the bulk being the JDT caches.

best regards,
Vlad

I'm not sure if this is relevant, but sometimes Buckminster materializes org.eclipse.jdt.ui in my workspace... Other times it just complains that it can't find it.

ERROR   [0001] : Unable to obtain resource .buckminster/org.eclipse.jdt.ui from <workspace>/org.eclipse.jdt.ui

Thomas, could you please say if the fact that the source update site is accessible via file:/ could be a problem? I will try to get a similar environment working on a machine with Internet access, to see if there is a difference.

Thanks,
/Vlad

I have exposed the local eclipse catalog as a web site with a simple web server and the only files requested are contents.jar and artifacts.jar, so it looks like buckminster stops trying early. The feeling I get is that useTargetPlatform="false" is ignored...
