Torkild,
In addition to any manual calls you may want to make to the p2.generator, 
there is some integration with PDE.Build.
Unfortunately there is not yet any documentation here.

If the org.eclipse.equinox.p2.metadata.generator bundle is present in the 
builder at script generation time, then there are potentially 4N + 1 
generated calls to the p2.generator.

For N configurations:
1) In the assemble.[feature].[config].xml scripts:      a) Once on 
assembled features and plugins
                                                b) a second time on 
assembled rootfiles.
2) In the package.[feature].[config].xml scripts:       a) Once of the 
packaged features and plugins
                                                b) again on rootfiles from 
packaging
And one final call:
3) In the assemble.all.xml or package.all.xml : A final call to generate a 
root product IU

These calls are all conditional on the "generate.p2.metadata" property 
being set.  In the case of a product build, the final result at the end of 
these calls is a repo with an installable product IU.
To get an actual p2ized install out of this, you then need to call the 
p2.director on the repo and install 

As an example, the SDK is built by first building a master zip containing 
everything.  p2.generator is called on this in a custom step to generate 
IUs for all the plugins and features.  Then the build runs the pde build 
packager with a .product file and metadata integration to assemble all the 
rootfiles and generate p2 data on them (steps 2 & 3 above).  Then finally 
in custom steps it calls p2.director to install the SDK and zip up the 
results.

-Andrew

Some properties to define are:
generate.p2.metadata=true
p2.metadata.repo = file:${buildDirectory}/repo
p2.artifact.repo = file:${buildDirectory}/repo
p2.metadata.repo.name = Meta Repo Name
p2.artifact.repo.name = Artifact Repo Name
p2.flavor = tooling
p2.publish.artifacts=true

Re: [equinox-dev] How to use p2.generator in PDE build







Hi Torkild, 

Here is a document describing the metadata generator: 

http://wiki.eclipse.org/Equinox_p2_Metadata_Generator 

The ant task doesn't yet have documentation, but it takes the same 
arguments as the generator application. You just need to convert the 
command line syntax to Ant syntax. For an example, you could look at the 
Eclipse project scripts that p2-enable the platform itself. See 
/cvsroot/eclipse/org.eclipse.releng.eclipsebuilder/equinox/buildConfigs/equinox.prov/run.xml,
 
particularly the "run.generator" target. 

Feel free to annotate the wiki page with any other details you find 
useful. 

John

[equinox-dev] How to use p2.generator in PDE build








Hi all,

I'm in the process of migrating our Eclipse based product to Ganymede and 
have 
a few issues with p2.

Building the product as usual using the PDE build scripts works nicely but 

creates a product that cannot be updated as it states 'Cannot launch the 
Update UI. This installation has not been configured properly for Software 

Updates.'

After quite a lot of digging I've found that the product must be p2-ized 
which 
seems like a good idea. I also found a reference to the "p2.generator" ANT 

task but absolutely no information on how to use it.

Could someone please point me to the right direction here? I guess I must 
use 
this task somewhere in customCallbacks.xml or the new customAssembly.xml 
but 
I cannot figure out where and which attributes to set.
