I will resume working on this after next week. Get a deadline out of nowhere…

If you materialize the releng project (after creating the TP project, the new empty target platform as explained, and make it active) the bundles and features for the target platform will be downloaded, and installed in the TP project.

But as I said, make sure to use the sources from the git repository (again, apologies, I’ll update the listings in this blog post I see from your next reply that you did not use the git repositories, thus, this might be the causes of your problem.

Note that the TP project is needed only when you build in Eclipse; headlessly, that is not required, since when materializing the target platform from a Jenkins job (or using the ant script) it will always start from an empty target platform.

You’ll see that once you got familiar with these concepts building will be really easy!

keep me posted about your progress.

I do have another question: what is the use of the TP project in this tutorial? Just to materialize the releng project? I cannot use it as “Target Platform” for Eclipse Preference. If I do use it as “Target Platform”, the bundle projects fail to build.

Thanks again,

Sam

First of all, are you using the sources from the git repository http://sourceforge.net/p/buckyexamples/bucky-mail-rcp/?branch=ref%2Fmaster ?
Because the listings you find in this blog post might be outdated (sorry, my fault, I’ll update them to reflect the actual sources).

If you run the site.p2 action you need to make sure that you are NOT using the “Running Platform”, but the “TP” you must have materialized in advanced. If you were using the Running Platform, then I guess you did not follow the step correctly

I’ve just tried
- to import in a clean workspace the sources from the git repository,
- then I prepared the TP project and the corresponding target platform
- I made sure that this new empty target platform is set as the current target platform
- (after this of course the eclipse project won’t compile since the target platform is still empty, so lots of dependencies are missing)
- then I resolved the cquery (takes some time to download all the dependencies for the target platform)
- when this is finished, the projects in the workspace compile fine
- then site.p2 works fine

Again, please make sure to use the sources from the git repositories which are up-to-date

Buckminster just works, but if you start messing with target platforms then it might get confused

the hibernate bundle is surely not part of the target platform that you materialize with the cquery, but it might be part of your current eclipse installation… but you must not use your eclipse installation as the target platform

please, let me know about your progress!

Something interesting here. I am at the beginning of the step of “Build a p2 Repository for our application”. After right clicking on the product.site project => Buckminster => Invoke Action…, select the properties file and select site.p2, I got error:

No component named org.hibernate.eclipse.libs:osgi.bundle$3.6.0.Final-v20130327-1513-B111 is known to Buckminster

Then I check Eclipse’s preferences of “Target Platform”: it is set to “Running Platform(Active)”. I switch to “TP”, the one I created at the beginning of the tutorial. Now projects “org.eclipse.buckminster.examples.rcp.mail.bundle” and “org.eclipse.buckminster.examples.rcp.mail.optional.bundle” failed to compile. I proceed anyway with Buckminster and get the following error:

The project was not built since its build path is incomplete. Cannot find the class file for org.eclipse.swt.widgets.Composite. Fix the build path then try building this project

Then I switch back Eclipse’s preferences of “Target Platform” to “Running Platform(Active)”. try Buckminster again, get “No component named org.hibernate.eclipse.libs…” again. but the funny part is, if I keep trying Buckminster several times, I do get one successful build! And if I get one through, if I continue to try Buckminster, most of time it is ok. However, if I close Eclipse and restart, I got “No component named org.hibernate.eclipse.libs…” again! Sometimes, I get different error like “No component named org.eclipse.e4.core.services:osgi.bundle/[1.0.0.v20120521-2346,1.0.0.v20120521-2346] is known to Buckminster”. (BTW, I don’t see any dependency on hibernate at all in the projects of your tutorial. The successful built repo has no hibernate related jar file either.)

Have you seen something like this? Is Buckminster really so mysterious/unstable?

Thanks

Sam

Thanks!
