An OSGi bundle that exports the javax.inject package.
Since a couple of years, the Eclipse platform jars are published on maven central with metadata that allows the consumption in a traditional maven project (no Eclipse Tycho required).
This article is my feedback after having experimented with PDE (the Plug-in Development Environment project).
The goal is to compile and execute code that requires this OSGi bundle from maven-central:
<dependency>
<groupId>org.eclipse.pde</groupId>
<artifactId>org.eclipse.pde.core</artifactId>
<version>3.13.200</version>
</dependency>I am using a regular maven project (with the bnd plugins to manage the OSGi related tasks). I do not have Eclipse Tycho, so maven do not have access to any P2 Update Site.
Amongst all dependencies of PDE, there is org.eclipse.e4.core.contexts and org.eclipse.e4.core.services. Those two bundles requires:
Import-Package: javax.inject;version="1.0.0",So we need a bundle exporting this package, otherwise the requirements are not fulfilled and I get this error:
[ERROR] Resolution failed. Capabilities satisfying the following requirements could not be found:
[<<INITIAL>>]
⇒ osgi.identity: (osgi.identity=org.eclipse.pde.core)
⇒ [org.eclipse.pde.core version=3.13.200.v20191202-2135]
⇒ osgi.wiring.bundle: (&(osgi.wiring.bundle=org.eclipse.e4.core.services)(bundle-version>=2.0.0)(!(bundle-version>=3.0.0)))
⇒ [org.eclipse.e4.core.services version=2.2.100.v20191122-2104]
⇒ osgi.wiring.package: (&(osgi.wiring.package=javax.inject)(version>=1.0.0))
[org.eclipse.e4.core.contexts version=1.8.300.v20191017-1404]
⇒ osgi.wiring.package: (&(osgi.wiring.package=javax.inject)(version>=1.0.0))
The bundle javax.inject version 1.0.0 is available in the Eclipse Orbit repositories.
The dependency used by most of the other libraries:
<dependency>
<groupId>javax.inject</groupId>
<artifactId>javax.inject</artifactId>
<version>1</version>
</dependency>This library does not contain any OSGi metadata in the published MANIFEST.MF.
See the corresponding open issue.
The jar from Eclipse Orbit is available at:
<dependency>
<groupId>at.bestsolution.efxclipse.eclipse</groupId>
<artifactId>javax.inject</artifactId>
<version>1.0.0</version>
</dependency>But this is not on maven central. You will need to add following repository to your pom.xml:
<repositories>
<repository>
<id>bestsolution</id>
<url>http://maven.bestsolution.at/efxclipse-releases/</url>
</repository>
</repositories>This question on stackoverflow gives some inputs and suggests:
From the Apache ServiceMix project:
<dependency>
<groupId>org.apache.servicemix.bundles</groupId>
<artifactId>org.apache.servicemix.bundles.javax-inject</artifactId>
<version>1_3</version>
</dependency>From the GlassFish project.
<dependency>
<groupId>org.glassfish.hk2.external</groupId>
<artifactId>javax.inject</artifactId>
<version>2.5.0-b62</version>
</dependency>After analyzing other candidates in list where artifactId == "javax.inject", there is also this one from the Lucee project:
<dependency>
<groupId>org.lucee</groupId>
<artifactId>javax.inject</artifactId>
<version>1.0.0</version>
</dependency>And on twitter Raymond Augé suggested the Apache geronimo project.
<dependency>
<groupId>org.apache.geronimo.specs</groupId>
<artifactId>geronimo-atinject_1.0_spec</artifactId>
<version>1.2</version>
</dependency>Make your choice.
