I'm trying to p2-enable our PDE build scripts, and have a couple of
general questions:
- Should the product be feature-based or plugin-based? What are the
implications of each?
- If I use a feature-based product, I get references to exact versions
(including a long checksum for some) to some features. Will I need to
update those when the target platform changes (say from 3.5.0 to 3.5.1),
or will the PDE build figure that out automatically?
- If I use a plugin-based product, how do I manage OS-specific plugins
and fragments? Ideally, I'd like to use the same product definition for
all host platforms.

In a product build, PDE/Build generates a top level feature that
represents your product. From this standpoint, the difference between
feature and plug-in based products is the build has to do a bit more
guessing about plug-ins when it adds them to the generated feature.
When adding plug-ins to the generated product feature, build will guess
a value for "unpack" and also possible ws/os/arch filter values.
So a feature based product would allow you finer control over these
guessed values. Features can also contribute root files to a product,
which is harder to do with plug-ins.

This depends on your features. When your feature includes
features/plug-ins, it can specify versions like:
- "0.0.0" - matches any version
- "3.5.0.qualifier" - matches 3.5.0.*
PDE/Build will automatically replace these with the actual versions
found at build time. (Though it only does this replacement on included
features/plug-ins, and not required ones.)
If you do this, then rebuilding your product against an updated target
will be enough to automatically increment the included versions.

Your .product file should list the superset of all the platforms.
PDE/Build will automatically set os/ws/arch attributes in the generated
product feature according to which of the platforms from the "configs"
property that the plugin/fragment matches.

This does not seem to work. When building on Windows, I get the
following error:

I finally got around to try to fix this.
I tried setting the configs property to "linux,gtk,x86_64", and
include the superset of all the plugin/fragments, but PDE build still
complains that it can't find org.eclipse.cdt.core.win32_0.0.0 (which is
a fragment, not a plugin).

I also tried setting "configs=*,*,*", but with the same error.
How do I go about debugging this? Is there a way to inspect the
generated feature?

In a product build, PDE/Build generates a top level feature that
represents your product. From this standpoint, the difference between
feature and plug-in based products is the build has to do a bit more
guessing about plug-ins when it adds them to the generated feature.
When adding plug-ins to the generated product feature, build will guess
a value for "unpack" and also possible ws/os/arch filter values.
So a feature based product would allow you finer control over these
guessed values. Features can also contribute root files to a product,
which is harder to do with plug-ins.

This depends on your features. When your feature includes
features/plug-ins, it can specify versions like:
- "0.0.0" - matches any version
- "3.5.0.qualifier" - matches 3.5.0.*
PDE/Build will automatically replace these with the actual versions
found at build time. (Though it only does this replacement on included
features/plug-ins, and not required ones.)
If you do this, then rebuilding your product against an updated target
will be enough to automatically increment the included versions.

Your .product file should list the superset of all the platforms.
PDE/Build will automatically set os/ws/arch attributes in the generated
product feature according to which of the platforms from the "configs"
property that the plugin/fragment matches.
