Switching rcp headless build (ant task) to use target platform [message #886264]

Hi there,

i've got an existing Product build using some ant build scripts that are called by a jenkins job. Everything worked fine over some years. Now the product is evolving from eclipse 3.2-base to indigo-base. Therefore we decided to define and use a target platform.

One of the build scripts calls a headless product build (see code below).
My goal is to change the headless build to use a target platform (defined by total amount of 4 directories) instead of a single eclipse directory.

Does anybody know how to revise the ant task below to achieve this goal?
I was hoping to find something like an additional parameter to state the .target-file defining the target platform.

My target platform is placed under version control. If there is no other way, i could always copy the four different directories into one directory and work like before, but i don't think it is a very good idea to do this, do you?
Earlier today I checked the buckminster-plugin but did not get to what I want to do.

Thanks for any help or hints,
Greets Alex

One way to do it is similar to the code we have in our customTargets.xml file: http://git.eclipse.org/c/e4/org.eclipse.e4.releng.git/tree/org.eclipse.e4.builder/builder/general/customTargets.xml#n111

First we use p2.mirror ant task to mirror our different target components into their own subdirectories of ${repoBaseLocation}.

The we use the p2.repo2runnable ant task to create a target platform from the different p2 repos.

Hi Paul,

thanks for the quick answer!
As I understand correctly, the result using the p2.repo2runnable will be a target platform copied in a given destination. This destination will have the content of my 4 source-directories and I will use the startup.jar, productBuild.xml etc. of the target platform for the task mentioned above?

I'll try and see what i can do with it.

Thanks
Alex

I think that PDE headless build doesn't support targets in same sense as
they work in PDE (IDE).

What I do in my continuous build job is to set target folder as headless
script's ${base} property (see online help for exact definition). This
property specifies folder that an application will be compiled against.
In result, it's identical to target platform purpose for not-headless
build from PDE UI.

Either way, you may also follow Paul. He's much more experienced that me
but I think that it's not an answer to what you asked us originally.

Libor is correct. We differentiate the basebuilder (what runs the PDE headless build) from the target platform (in my example, created by repo2runnable). My repo2runnable is not actually runnable Smile

but it is resolvable by the OSGi resolver, and can be used as the target platform for a build.
