Hybrid .target + targlet project [message #1760728]

Hi,

Is there a way that I can use Targlets to add to the target platform of a project that uses a .target definition as its core target platform specification mechanism?

I have a project that uses a .target definition which I cannot change. I think this .target definition lacks some 'development' utilities, say for example swt spy or git.

I would like to keep using the .target file but add to it with targlets. Some component would probably need to translate the .target into a targlet model and combine this model with my native targlets defined in the oomph setup. Currently that component is me, converting the target to targlet by hand which is a pita, especially since the .target changes quite often.

You can drag a .target file onto a Targlet Task...

Hi,

So, the .target file changes often, and I have several branches too.. So I really think that either I shouldn't do this conversion at all, or I should do it automatically.

Do you think it could be possible that I write a custom task which adds to the targlet container automatically? Maybe adding a flag to the Target platform task "Merge into Modular Target", or by adding an annotation on a targlet container?

Oomph can generate the .target file as a side-effective of resolving the Targlet. It uses annotations for that. You can see an example of that in Oomph.setup. Wouldn't that be better?

It would totally be better this way, but it's sadly not my competence. Either I do target->targlet or I ditch the targlet format completely and rely on target task instead and lose all the cool things that targlets offer.

It's pretty trivial like this on one of the Targlets of any Targlet Task:

<?xml version="1.0" encoding="UTF-8"?>
<base:Annotation
    xmi:version="2.0"
    xmlns:xmi="http://www.omg.org/XMI"
    xmlns:base="http://www.eclipse.org/oomph/base/1.0"
    source="http:/www.eclipse.org/oomph/targlets/TargetDefinitionGenerator">
  <detail key="location">
    <value>${git.clone.oomph.location/releng/org.eclipse.oomph.parent/tp/org.eclipse.oomph.tp.target}</value>
  </detail>
  <detail key="extraUnits">
    <value>org.eclipse.equinox.executable.feature.group</value>
  </detail>
  <detail key="singleLocation">
    <value>true</value>
  </detail>
  <detail key="includeAllPlatforms">
    <value>false</value>
  </detail>
  <detail key="includeSource">
    <value>true</value>
  </detail>
</base:Annotation>

Of course you have to modify this to use the location in your clone where the *.target is located, but that's it. It would also be possible to using the ${eclipse.target.platform} variable (or whatever variable you're using to choose the repository list) to generated different *.target files for different TP choices.

You can also drag and drop a *.target file onto a Targlet Task, so given that, it should be possible in principle to convert it on the fly.
