Re: [p2-dev] Avoiding JRE IUs and Generator Mode?
|
I'm starting the publisher docs here:
http://wiki.eclipse.org/Equinox/p2/PublisherThere is still long way to go, but it's a start.
This brings up a good question. Andrew, should I include the PDE Build publishing related tasks (the ones contributed by build) in this documentation?
cheers,
ian

There are these:
Contributed by org.eclipse.pde.build:
eclipse.gatherFeature : publish a feature
from source (ie feature has build.properties), also does the root properties.
implemented by GatherFeatureTask.
eclipse.gatherBundle : publish a bundle
from source (.class files have been compiled), implemented by GatherBundleTask
eclipse.publish.featuresAndBundles :
publishes binary features/bundles. Also does categories. implemented
by FeaturesAndBundlesTask
eclipse.brand.p2.artifacts : brands
launcher artifacts for a product (normally provided by org.eclipse.equinox.executable),
changes launcher name/icon, etc. Republishes them under a new IU
matching the product.
The two eclipse.gather* tasks are used
by pde.build to create the jars from source during a publish.bin.parts
target in the generated build.xml, this replaces the gather.bin.parts from
before.
Contributed by org.eclipse.equinox.p2.publisher:
p2.publish.featuresAndBundles : just
like eclipse.publish.featuresAndBundles above, but doesn't do categories.
implemented by FeaturesAndBundlesPublisherTask
p2.publish.product : publish a .product
file assuming required things are already in the repo, implemented by ProductPublisherTask.
This will publish a JRE IU, which will be required if your product
includes bundles that import packages that are provided by the system.
p2.publisher : I don't know about this
one, might not be tested. probably a replacement of p2.generator,
implemented by PublisherTask
Contributed by org.eclipse.equinox.p2.repository.tools
p2.repo2runnable : transform repositories
into "runnable" form which can be compiled against., Repo2RunnableTask
p2.mirror : mirroring for artifacts
and metadata, with slicing and filters. MirrorTask
p2.process.artifacts : optionally sign/condition/pack
jars using the jarprocessor task. Also update the artifact repo with
new descriptors for pack200 and update the MD5 sums to match the artifacts.
ProcessRepoTask
p2.composite.repository: create composite
repositories. CompositeRepositoryTask
Both the build and publisher tasks above
support the p2.inf file. For bundles and features, the difference
is the pde.build gather tasks publish directly from source at build time.
For these tasks, you don't actually need to include the p2.inf in
your binary bundles (although you can), it just needs to be there with
the source. The publisher featuresAndBundles task publishes from
binary jars, so you do need to included the p2.inf in the jar if you are
using it.
(Note, in all of the above, when I say
source, I mean your project checked out from CVS, not a generated source
bundle org.foo.source.)

Aha - well I didn't realize that
was an old task. So, the tasks I can use that are not documented
- where are they located source-wise? I'm fine digging through source.
I have found that the PDE call to "eclipse.gatherFeature"
seems to work without the JRE cruft as well.
However, the "p2.publish.featuresAndBundles"
task seems to be what I need. Does this handle p2.inf when it is
called? I'm a little confused as to when this file is needed. Is
it just a "publish-time" thing, or is it needed at build time
as well. I guess what I am asking is - should I just build my features
and plugins the way I always did, but include the p2.inf file in my JAR,
then later use it as part of a publish or metadata generation step?

Mark,
I don't see any way to turn off the generation of this IU using that task.
The incremental mode keeps the results of the generation around in memory
so that the next invocation of the task will add to them. Mode "final"
will then clear those accumulated results and also generate a parent container
IU if a .product file is used or root id is provided.
Note that this "p2.generator" task is the 3.4 based metadata
generator. 3.5 has a new publisher which supports more customization
(through the p2.inf file) that the generator didn't. There are publisher
tasks that could be used to avoid the jre IU if you were only doing features,
unfortunately they aren't yet documented.
The "p2.publish.featuresAndBundles" task will publish built feature
and plugin jars. It supports a "source" attribute
specifying a directory containing features and plugins subfolders. It
also supports nested <features> and <bundles> elements which
are ant Filesets specifying features and bundles to publish. It also
has the following attributes that should correspond to the same thing on
the p2.generator task: artifactRepository, metadataRepository, artifactRepositoryName,
metadataRepositoryName, append, compress, publishArtifacts. Using
this task won't create jre IUs.

Hi There,
I am trying to integrate the P2 stuff into my build and I am getting
entries in my metadata for individual features like this:
<unit id='config.a.jre' version='1.6.0' singleton='false'>
...
</unit>
<unit id='a.jre' version='1.6.0' singleton='false'>
<provides size='159'>
<provided namespace='org.eclipse.equinox.p2.iu' name='a.jre'
version='1.6.0'/>
....
</unit>
I am calling the "p2.generator" Ant task with noDefaultIUs set
to "true"
(which avoids generating a whole pile of cruft), but the JRE stuff still
gets in there. Is there any way to avoid the JRE stuff? I plan
on
merging all of my metadata at the end when I combine all of my features
into one large repository.
Also, what is the difference between "incremental" mode and "final"
mode? I build my features individually using a custom set of scripts
and I think I want mode="final", but I'd like to know that the
difference is between the two.
Thanks,
Mark.
