How to build a p2 site for the Eclipse delta pack?

Question

I am trying to build my own p2 update site for the Eclipse delta site (since it is not available as p2 update site).

What I did:

 # Get the delta pack from Eclipse web site
 #
 wget http://mirror.cc.columbia.edu/pub/software/eclipse/eclipse/downloads/drops/R-3.7.2-201202080800/eclipse-3.7.2-delta-pack.zip

 # Unzip in its own directory (delta)
 #
 mkdir delta
 cd delta
 unzip ../eclipse-3.7.2-delta-pack.zip
 cd ../

 # Get Eclipse from Eclipse web site (in theory we could only get equinox,
 # but in pratice, it refused to start due to some race conditions.  Using
 # eclipse works out-of-the-box)
 #
 wget http://mirror.cc.columbia.edu/pub/software/eclipse/eclipse/downloads/drops/R-3.7.2-201202080800/eclipse-3.7.2-delta-pack.zip

 # Untar Eclipse (it creates an "eclipse" directory)
 #
 tar xzvf eclipse-java-indigo-SR2-linux-gtk-x86_64.tar.gz

 # Create (publish) a p2 site out of the delta features/plugins
 #
 ./eclipse/eclipse -console -consolelog -nosplash -debug -verbose        \
    -application org.eclipse.equinox.p2.publisher.FeaturesAndBundlesPublisher       \
    -metadataRepository file:${Repository}  \
    -artifactRepository file:${Repository}  \
    -source delta/eclipse                   \
    -configs ANY            \
    -publishArtifacts

That creates in ${Repository} the following structure:

which I can check using an URL http://my.server/delta.

When I add the url in my parent pom:

        <repositories>
            <repository>
                    <id>delta</id>
                    <layout>p2</layout>
                    <url>http://my.server/delta</url>
            </repository>
            <repository>
                    <id>eclipse-platform</id>
                    <layout>p2</layout>
                    <url>http://download.eclipse.org/releases/indigo</url>
            </repository>

It does not pick up the plugins my project needs:

[INFO] Cannot complete the request.  Generating details.
[INFO] Cannot complete the request.  Generating details.
[INFO] {osgi.ws=win32, osgi.os=win32, osgi.arch=x86_64, org.eclipse.update.install.features=true}

[ERROR]   Missing requirement: com.example.fs 1.0.0.qualifier requires 'org.eclipse.ui.carbon 0.0.0' but it could not be found

The plugin org.eclipse.ui.carbon is in the generated contents.xml and artifacts.xml files and also in the plugins directory:

/<...>/local/apache2/htdocs/delta
    |-- artifacts.xml
    |-- content.xml
    |-- features
    `-- plugins

I am not sure why maven cannot get the plugin from the update site. How can I debug/fix this ?

Answer 1

Actually I talked too soon. While the update site /eclipse/updates/3.7 has the "Eclipse Platform Launchers" I do not see how to get for all platforms.

I did get the "Eclipse Platform Launchers" but now my product is missing the following plugin. We need those plugins to build the product for several platforms:

<plugin id="org.eclipse.swt.carbon.macosx" fragment="true"/>
<plugin id="org.eclipse.swt.cocoa.macosx" fragment="true"/>
<plugin id="org.eclipse.swt.cocoa.macosx.x86_64" fragment="true"/>
<plugin id="org.eclipse.swt.gtk.aix.ppc" fragment="true"/>
<plugin id="org.eclipse.swt.gtk.aix.ppc64" fragment="true"/>
<plugin id="org.eclipse.swt.gtk.hpux.ia64_32" fragment="true"/>
<plugin id="org.eclipse.swt.gtk.linux.ppc64" fragment="true"/>
<plugin id="org.eclipse.swt.gtk.linux.s390" fragment="true"/>
<plugin id="org.eclipse.swt.gtk.linux.s390x" fragment="true"/>
<plugin id="org.eclipse.swt.gtk.linux.x86" fragment="true"/>
<plugin id="org.eclipse.swt.gtk.linux.x86_64" fragment="true"/>
<plugin id="org.eclipse.swt.gtk.solaris.sparc" fragment="true"/>
<plugin id="org.eclipse.swt.gtk.solaris.x86" fragment="true"/>
<plugin id="org.eclipse.swt.win32.win32.x86" fragment="true"/>

That the reason why I initially used the delta pack in the first place.

I guess the question was more: How do you build a product for several platforms using Software Updates sites only ?

Answer 2

The Delta Pack contents are already available in the "Eclipse Project Updates" update site (e.g. http://download.eclipse.org/eclipse/updates/4.3 for Kepler). Just include the feature groups Eclipse RCP and Equinox Target Components in your target platform.
