Hi Alain,
The general rule of thumb when using Buckminster is that if you can build it in your IDE, you should be able to build
the same thing headlessly. Your workspace is built the same way regardless. Are you encountering any specific problems?

Thomas Hallgren

Hi Thomas,
thanks a lot for your answer.
In the IDE, I have installed the AJDT feature that exports a builder for
the projects that uses AspectJ.
In the .project file we have now the following lines that replaces the
"org.eclipse.jdt.core.javabuilder" buildCommand:
<buildCommand>
<name>org.eclipse.ajdt.core.ajbuilder</name>
<arguments>
</arguments>
</buildCommand>
But for the headless buckminster build, a headless ajbuilder is missing.
There is a workaround for headless pde build. But I'm not shure if I can
use the same workaround for the buckminster build.
The steps to follow in order to implement the workaround are as follows
(see https://bugs.eclipse.org/bugs/show_bug.cgi?id=252641):
1. unzip the plugin into your eclipse/dropins directory.
2. run eclipse once so that this plugin is recognized and installed by
the P2
installer
3. in your headless build script, make sure that the eclipse antrunner
points
to the org.eclipse.ajdt.pde.build/scripts/build.xml ant script
4. ensure that the following property is available to ant:
ajdt.pdebuild.home =
<path_to_ajdt.pde_plugin> (you can add this as a vm arg to
-Dajdt.pdebuild.home=<path_to_ajdt.pde_plugin>)
5. run your build script
How to implement the point 3 if I want to use buckminster?
So my question was, if anybody have already solved this issue.
Kind regards,
Alain.

Hi Alain,
I'm trying to understand why you would need a workaround in the first place. When using Buckminster, you won't run into
any limitations that might exist when you run a PDE build headlessly.
So if you have your build running in your IDE, perhaps you should just try and run it headlessly with Buckminster and
see if it works. If it doesn't, then we can take it from there.
Regards,
Thomas Hallgren

Hi Thomas
Thanks for your answer.
As far as I see the problem is as follows:
1. I can't install the original AJDT plugin (that i use in my IDE) into
a hedless environment, because if I do so, a exception will be thrown,
that the SWTException class is missing.
2. Instead of that, I install the "org.eclipse.ajdt.pde.build" plugin
that, do to the description, supports the build of aspectj plugins
headlessly.
3. Because the projects (using aspectj) does not have a
org.eclipse.jdt.core.javabuilder build-command no classes will be built
using a default headless installation (whitout
org.eclipse.jdt.core.javabuilder).
As effect, simply the class can not be found e.g. "NameProvider cannot
be resolved"
4. That the plugin org.eclipse.jdt.core.javabuilder takes effect, the
documentation sais, that I should make shure, that the eclipse antrunner
points to the org.eclipse.ajdt.pde.build/scripts/build.xml ant script.
And now the question: How to do this for buckminster?
Thanks for your response,
Alain.

Hi Alain,
Please install the org.eclipse.buckminster.pde.headless.feature into your headless buckminster. It contains the javabuilder.
I don't know what the build.xml in question does, or where it's supposed to get called from, so I cannot advice on #4.

Thomas Hallgren

That's right. Buckminster will not call that. We just build as you normally would build when you have the workspace in
the IDE. No special tricks are used in a headless environment.
