Hi,

Tycho sound good, but misses the target for our specific project (the story is to full of details to explain it here).

The only working solution i found (including maven 3-alpha-1) is to
extend m2.conf to:
--------------------------
[plexus.core]
load ${maven.home}/extentions/*.jar
load ${maven.home}/lib/*.jar
--------------------------
Then put the component-jars in the newly created directory "extentions".
now maven picks them up and i can use my eclipse plugins as dependencies, transparently in maven. Also no need to add the extensions tag to the pom.

I tested this solution with maven 2.0.9 and 3-alpha-1 and both worked correctly.

I would prefer a solution just involving the project pom, but this is ok too because it only triggers when i use the repository layout "eclipse".

When there are others needing such a possibility, e-mail me! Maybe i can convince my customer to give it free.

regards,
Ritchie

Richard,

I wonder if you have seen Tycho [1]? This is one of the projects I work on, so I am biased ;-) but I believe it should address your problem, i.e. building eclipse rcp application with maven.

Hi,

i am having troubles activating a plexus ArtifactRepositoryLayout component from a pom. I tried the notation:
<extensions>
 <extension>
    <groupId>xxx</groupId>
    <artifactId>xxx</artifactId>
    <version>xxx</version>
  </extension>
</extensions>
but it didn't pick up the component.

The reason of doning this is that after bending maven builds to create eclipse rcp applications for a long time, i want to try a different approach. By creating a plexus "ArtifactRepositoryLayout" that understands a eclipse installation, that works out pretty well!

We have a complete eclipse-rcp tgz/zip in the repository and extract it on demand during the build. the Eclipse-ArtifactRepositoryLayout takes up this directory structure and points the dependency:

    <repositories>
        <repository>
            <id>eclipse-local</id>
            <layout>eclipse</layout>
<url>file:/.../org.eclipse.rcp.target-eclipse.3.4.1.0/eclipse</url>
        </repository>
    </repositories>
....
    <dependency>
        <groupId>org.eclipse.rcp</groupId>
        <artifactId>org.eclipse.swt</artifactId>
        <version>3.4.1.0</version>
    </dependency>

to "plugins/org.eclipse.swt_3.4.1.v3449c.jar" and generates a (temporary) pom for this dependency from the manifest of the eclipse-plugin.

So far so good.. my problem is that i have to copy the plexus component with the Eclipse-ArtifactRepositoryLayout in to the maven2/lib directory to activate it, is there any way to activate it from inside the pom?

Thanks for any help,
Richard van Nieuwenhoven

My prerequisites (and the solution satisfies them so far):
- use only eclipse plugins that are contained in the same stable version.
- We do not want to "pollute" the repository with all the versions from eclipse plugins and features. - We so not want to know the correct version of plugin org.eclipse.xxxx.xxx. we just want the version bundled with eclipse version "3.4.1" for example.
