Fragment is unable to resolve a class in host [message #650619]

Hi,

I am currently use cruise control, ant, and perl script to build the system and I am trying to switch to Hudson and Buckminster and so far I am able to build some subsystems nicely.

But I have a problem. On one sub-system, I have a plugin defines an interface and a bunch of fragment implement the interface for all the supported platforms. Buckminster import all the fragments from SVN but at the build step, except for the fragment on the running platform, all other fragments are unable to resolve the interface defined in the host. So, the buckmister build step fails.

Please not that in each of the fragment, we use Bundle-NativeCode and Eclipse-PlatformFilter to select the correct fragment for the target platform.

Can anyone give me the idea on solving this issue?

Thanks,

Paul

For Cross-Platform builds you usually need to work with a platform
agnostic target platform.
If your target platform is defined by a .target file you can set that
directly in the 'environment' section inside the target definition editor.
If you do not use a target definition file you can work with the
buckminster setpref command and change targetWS, targetOS and targetArch
to '*'

Best regards,
Johannes

Hi Johannes,

Thank you for your help. Sorry for the delay on the response as I was away for a few days.

My target platform is defined by a .target file. After setting os, ws and arch to *, I was able to generate all jars for all plugins including the plugins that are targeting the running platform.

Thanks again.

Paul

I got some updates...

After removing Hudson's workspace, the same errors came back.

So, I have to do run a build for the 'running platform' with os=win32, ws=win32, arch=x86_64 options on the target platform file and the buckminster.properties file.

Once the initial build above ran successfully, the next build with os=*, ws=* and arch=* (on both target file and buckminster.properties file) also ran successfully.

It seems strange but at least it works.

Thanks,

Paul.

I have the same problem when I clear my Hudson workspace. I just run the build twice (both times I use os=*, ws=* and arch=*) and the second build works as expected.

Hi Philip,

You are right. The second build works with both times having os=*, ws=* and arch=*. This is great since I don't have to change the target.platform and buckminster.properties files everytime I clear my workspace.

Thanks,

Paul
