P2Gradle

https://plugins.gradle.org/plugin/it.filippor.p2

this plugin launch an osgi framework with eclipse p2 bundle to perform the resolve and publish task

Example

gradle kotlin dsl see https://github.com/filippor/p2Gradle/blob/master/p2test/build.gradle.kts

gradle groovy dsl see https://github.com/filippor/p2Gradle/blob/master/testGroovy/build.gradle

Apply plugin

plugins {
    id ("java-library")
    id ("it.filippor.p2") version ( "0.0.13")
}

the plugin download the eclipse provided bundle from maven central so it add maven central repository

Set the updateSite to get the bundle

p2.updateSites = listOf(
	uri("http://download.eclipse.org/releases/2019-12"),
	uri("http://download.eclipse.org/releases/2019-06")
)

define dependencies

dependencies {
  api(p2.bundles("org.eclipse.core.resources:[3.13,3.14)"))
}

api is a gradle configuration you can use any configuration.

the version range can be omitted and is defined as

	  range ::= interval | atleast
	  interval ::= ( '[' | '(' ) left ',' right ( ']' | ')' )
	  left ::= version
	  right ::= version
	  atleast ::= version

the default behavior is to include the transitive dependency to use only declared dependency use

dependencies {
  api(p2.bundles(false,"org.eclipse.core.resources:[3.13,3.14)"))
}

publish to repository

p2.publishTask("p2publish") {
	repo = buildDir.toPath().resolve("targetSite").toUri()
	bundles = configurations.getByName("runtimeClasspath")
}

p2publish is the name of the task that can be invoked

to select the target repository use setRepo with desidered uri

setBundles accept any Iterable and publish the file on repository

Notes

If used with plugin biz.aQute.bnd.builder becouse gredle classpath is not isolate it.filippor.p2 plugin nedd to be applied before biz.aQute.bnd.builder

The local cache for the p2 repository is located at <user.home>/.gradle/caches/p2/pool but can be configured with p2.setBundleCache(Path)

the plugin create a configuration named p2frameworkBundles that contains the bundles installed in the osgi framework to execute the provisioning operation
