Transitive dependencies not resolved with maven dependency and tycho pomConsider option

Question

I try to create an eclipse plugin using OSGI dependencies from two repositories, one with maven dependencies, and one with p2 dependencies :

<repositories>
<repository>
  <snapshots>
      <enabled>true</enabled>
  </snapshots>
  <id>bintray-anrgenstar-genstar-packages</id>
  <name>bintray</name>
  <url>http://dl.bintray.com/anrgenstar/genstar-packages</url>
  </repository>
</repositories>

<repository>
    <id>gama</id>
    <name>GAMA Snapshots</name>
    <url>http://gama.unthinkingdepths.fr</url>
    <layout>p2</layout>
    <releases>
        <enabled>true</enabled>
    </releases>
    <snapshots>
        <enabled>true</enabled>
    </snapshots>
</repository>

The project contain one parent pom.xml into ummisco.gaml.extensions.parent, which build the eclipse plugin ummisco.gaml.extensions.genstar :

• (1) ummisco.gaml.extensions.parent
  • pom.xml
• (2) ummisco.gaml.extensions.genstar
  • pom.xml
  • src/...
  • META-INF/MANIFEST.MF

(1) The ummisco.gaml.extensions.genstar parent pom.xml define the module <module>../ummisco.gaml.extensions.genstar</module> to build and call the Tycho maven plugin :

<modelVersion>4.0.0</modelVersion>

(2) The eclipse-plugin pom.xml of ummisco.gaml.extensions.genstar which need p2 and maven dependencies to work use the tycho <pomDependencies>consider</pomDependencies> option.

The MANIFEST.MF for this eclipse-plugin is defined like that :

Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: Genstar
Bundle-SymbolicName: ummisco.gaml.extensions.genstar;singleton:=true
Bundle-Version: 1.7.0.qualifier
Bundle-RequiredExecutionEnvironment: JavaSE-1.8
Require-Bundle: msi.gama.core, core, gspl, spin, spll,
 javax.xml;bundle-version="1.3.4"

When i try to mvn clean install into ummisco.gaml.extensions.parent it seems that tycho download and recognize the dependencies defined in p2 (msi.gama.core for example), and defined in pom.xml (core, spll,gospl, spin OSGI bundle), but transitive dependencies of these bundles are not resolved.

I verify the transitive dependencies of the OSGI Bundle core 1.0.0 manifest (using mvn dependency:tree) and it seems correct, the manifest contain the declaration of dependencies in Import-Package, like org.math.R as you can see here :

I really don't understand why the transitive dependencies are not automaticly resolved by tycho using the pom.xml dependency ... If tycho recognized the core, spll, spin, etc. package in the eclipse-plugin MANIFEST, why the transitive dependencies of core, spll, spin, gospl OSGI bundle are not downloaded ?

Do you think there is a solution for this problem ?

UPDATE

Following this repository i try to make two project :

• maven-bundle which bundle all dependencies into one big jar
• tycho-bundle which take this maven-bundle in dependency

Intelij Idea found the different dependency class when i compile in GUI mode, but not my maven project when i run mvn install, it's really really weird... I don't understand where is the problem.

You can find the archive of the project here, you need to mvn clean install pom.xml into /maven-bundle/ folder, then mvn clean install pom.xml into tycho-bundle/ folder.
