Product Builds with p2

Defining the new property:

p2.gathering = true

will cause a few changes for product builds. In particular, the build will produce properly installed fully p2 enabled products.

The following is a list of related properties (old and new):

p2.gatheringSet to true to turn on p2 publisher based builds.
p2.build.repoThe local build time p2 repository, default is ${buildDirectory}/buildRepo. Results will be mirrored from here to the final archive location.
generate.p2.metadataThis is property for the old metadata generator integration. It has no affect when p2.gathering=true.
p2.metadata.repo
p2.artifact.repo
By default for product builds, the final archives are the installed products and metadata and artifacts are left in the ${p2.build.repo}. If p2.metadata.repo and p2.artifact.repo are defined, then the artifacts and metadata for the product will be mirrored from the build repository.
p2.metadata.repo.name
p2.artifact.repo.name
Optional, these properties will be used to name the final repository when p2.metadata.repo and p2.artifact.repo are used.
p2.compressSet to true to compress the final repository xml into a jar.
p2.flavorThe flavor of the product, used as a qualifier on the configuration metadata for the product. See below.
p2.product.qualifierThe qualifier to use when replacing "1.0.0.qualifier" in a product's version. If not set, the qualifier will be based on forceContextQualifier or the timestamp.
p2.publish.artifactsNo affect when p2.gathering=true (Old property)
p2.root.name
p2.root.version
No affect when p2.gathering=true (Old property)
p2.context.reposDefine context repositories. See reusing metadata.
repoBaseLocationA folder containing repositories to transform using <p2.repo2runnable>. See also reusing metadata.
transformedRepoLocationThe folder containing the output of <p2.repo2runnable>. See also reusing metadata.
p2.category.siteA URL to a site.xml file used to define categories.
p2.category.definitionA URL to a category.xml file used to define categories.
p2.category.prefixDefine a prefix to ensure unique ids for category IUs generated from site/category files that don't use unique names.
skipMirroringSkip the final mirroring from ${p2.build.repo} to ${p2.metadata.repo}.
skipDirectorSkip the call to the director. No installed products will be produced. If p2.metadata.repo and p2.artifact.repo are defined, those repositories will contain the product metadata and artifacts, otherwise ${p2.build.repo} will contain the results.
p2.director.logLocation of a log file to log the results of the director call.
p2.director.profileThe name to use for the p2 profile created by the director. Generally it is a good idea to name this something related to your product. Default is "profile".
p2.director.extraArgsExtra arguments to pass to the directory. Default is "-profileProperties org.eclipse.update.install.features=true".

Product Flavor

As part of a product build, PDE/Build automatically generates default configuration metadata to set start levels and config.ini property. This metadata is commonly referred to as Configuration Units (CUs). In particular, start levels are set using CU fragments on the IU for the bundle being started. The flavor is used as a qualifier when generating the CU's name based on the IU.

For example, with "p2.flavor = tooling", 'toolingwin32.win32.x86org.eclipse.core.runtime' will be the name of the CU that configures the org.eclipse.core.runtime bundle on windows. It may be a good idea to use a flavor based on your product id to avoid conflicts with other metadata, particularly if your product has particular needs with respect to start levels.

See also the configuring products page.

The director call

PDE/Build includes a runDirector target that is called to perform installs during a product build. Currently, this is a fork of the director application in a new process. In more advanced releng scenarios, it is possible to reuse this task to perform additional installs. The task requires that the location of the equinox launcher for the builder is defined. An example call would look something like this:
	<property name="equinoxLauncherJar" value="/builder/eclipse/plugins/org.eclipse.equinox.launcher_1.0.200.v20090520.jar"/>
	<ant antfile="${eclipse.pdebuild.scripts}/genericTargets.xml" target="runDirector" inheritAll="true">
		<property name="ws" value="gtk"/>
		<property name="os" value="linux"/>
		<property name="arch" value="x86"/>
		<property name="p2.director.installPath" value="${installFolder}"/>
		<property name="p2.repo" value="${p2.build.repo}"/>
		<property name="p2.director.iu" value="my.rcp.product"/>
		<property name="p2.director.version" value="1.0.0"/>
	</ant>
