Difference between org. .. .observable and org. .. .observable.source [message #986538]

Hi,
this is probably a stupid question but i just can't find a answer with google.
I am at the last steps of a RCP tutorial and at this step I have to add the dependency

org.eclipse.core.databinding.observable

to my META.INF. But I can only add org.eclipse.core.databinding.observable.source
When I download the example code to the tutorial they have added the "org.eclipse.core.databinding.observable". How comes that I can't find it?
My suggestion is that the .source package is simply more general, but I don't want to rely on this suggestion.
So whats the difference between .source and "normal" packages?

And since I'm already here: Can you tell me when I have to add dependencies to my product file and when they belong into the META-INF? What es the difference?

Thank you!

The .source one holds the Java-Source-Files whereas the one without
..source holds the .class-Files.

Have a look in the /plugins directory of your eclipse installation. You should find two jars like these:

org.eclipse.core.databinding.observable.source_1.4.1.v20120521-2329.jar
org.eclipse.core.databinding.observable_1.4.1.v20120521-2329.jar

As Thomas said the first one just contains the java-sources and is optional, while you need the second one at compile and runtime.

Hm okay, thank you.
I found the file in my directory but why don't I have access to it? when I type "org.eclipse.core.dat" I can just choose the source file

Please post your MANIFEST.MF. Maybe 'org.eclipse.core.databinding.observable' is already included? Did you customize your target definition?

Hi,

I checked your statement and I can also not include org.eclipse.core.databinding.observable. This is because I have the dependency to org.eclipse.core.databinding included, which itself has a depencency to the observable plugin. So you don't have to add it manually again, as it is already included transitively. Have a look at your product configuration. In the dependencies section you should find the observable plugin.

If you want to check which bundles are loaded and active you can check this via the OSGi console in Eclipse. Just open it from the console view in Eclipse and check like described here

The dependency is not the important fact but that core.databinding
reexports the obserable one.

Thanks for pointing to this. I just missed the little grey arrow in the manifest editor. Smile
