Bug 331588

Description Robert M. Fuhrer 2010-12-01 14:10:51 EST

[FWIW, my problem seems strongly related to bug #320408, hence my posting as a bug rather than on a newsgroup. Apologies if this turns out not to be appropriate...]

I'm investigating using Buckminster as the build engine for the IMP project (http://www.eclipse.org/imp). [Right now, we're using PDE-derived Ant scripts.]

To get started, I followed the Buckminster tutorial at http://www.ralfebert.de/blog/eclipsercp/rcp_builds/ and got the following error when building the p2 site using "Buckminster" => "Invoke Action" => "site.p2":

    No component named org.eclipse.swt.motif.solaris.sparc:osgi.bundle/[3.6.1.v3655c,3.6.1.v3655c](&(target.arch=sparc)(target.os=solaris)(target.ws=motif)) is known to Buckminster

However, the active Target Platform *does* have the above-cited bundle.

==========

I'm running Helios 3.6.1 on Mac OS X, using Java 6 (1.6.0_22-b04-307-10M3261). I installed Buckminster from the Helios update site, and got "Buckminster - Core 1.3.1.r11579".

==========

Here are the steps I followed:

0) Create Target Platform:

I created an empty Target Platform, and added to it the "Eclipse RCP SDK" and "Eclipse Platform Launchers" features from the Helios site http://download.eclipse.org/releases/helios. I set this as the active Target Platform. I shared this as a file in the workspace; its content was:

    <?xml version="1.0" encoding="UTF-8" standalone="no"?>
    <?pde version="3.6"?>
    <target name="Eclipse RCP">
        <locations>
            <location includeAllPlatforms="true" includeMode="slicer" type="InstallableUnit">
                <unit id="org.eclipse.equinox.executable.feature.group" version="3.4.1.R36x_v20100823-7M7K7JF90dnJ-WLf3cf4yi"/>
                <unit id="org.eclipse.rcp.sdk.id" version="3.6.0.M20100909-0800"/>
                <repository location="http://download.eclipse.org/releases/helios"/>
            </location>
        </locations>
    </target>


1) Create an RCP application, com.example.mail, using the RCP Mail template.

2) Create a feature project, com.example.mail.feature, that includes this bundle.

3) Create a product configuration that contains the above feature.

    <?xml version="1.0" encoding="UTF-8"?>
    <?pde version="3.5"?>

    <product name="Mail" uid="com.example.mail.product" id="com.example.mail.product"
             application="com.example.mail.application" version="1.0.0" useFeatures="true"
             includeLaunchers="true">

        <configIni use="default"/>

        <launcherArgs>
            <vmArgsMac>-XstartOnFirstThread -Dorg.eclipse.swt.internal.carbon.smallFonts</vmArgsMac>
        </launcherArgs>

        <plugins/>

        <features>
            <feature id="com.example.mail.feature" version="1.0.0.qualifier"/>
        </features>
    </product>

4) Create a feature project, com.example.mail.site, which includes the above feature. Its feature.xml:

    <?xml version="1.0" encoding="UTF-8"?>
    <feature id="com.example.mail.site" label="Site" version="1.0.0.qualifier" provider-name="me">
       <description url="http://www.example.com/description"> ... </description>
       <copyright url="http://www.example.com/copyright"> ... </copyright>
       <license url="http://www.example.com/license"> ... </license>

       <includes id="com.example.mail.feature" version="0.0.0"/>
    </feature>

I test-launched the product and it seemed to behave properly.

5) Create buckminster.properties with the following contents:

    buckminster.output=${user.home}/tmp/mail
    buckminster.temp.root=${user.home}/tmp/buildtmp
    qualifier.replacement.*=generator:lastRevision

    target.os=*
    target.ws=*
    target.arch=*

6) I right-clicked on my site project (com.example.mail.site) and invoked "Buckminster" => "Invoke Action" and selected "site.p2" from the dialog. The result was the following error:

    No component named org.eclipse.swt.motif.solaris.sparc:osgi.bundle/[3.6.1.v3655c,3.6.1.v3655c](&(target.arch=sparc)(target.os=solaris)(target.ws=motif)) is known to Buckminster

   True enough, if I look into where I think Buckminster/p2 caches the components in the Target Platform, I see what looks like all of the RCP bundles, but not the one cited in the error message.

    $ cd <myworkspace>/.metadata/.plugins/org.eclipse.pde.core/.bundle_pool/
    $ ls plugins
    ... <no sign of the SWT motif/solaris/sparc bundle>
    $

7) Reading through the comments on bug 320408, I saw the advice to add the Helios update site to the rmap file. I don't have an rmap file, since the tutorial implies I don't need one (yet?).

   Still, I thought perhaps modifying my Target Platform might have the same effect. So, I added the Helios update site http://download.eclipse.org/eclipse/updates/3.6 to the Target Platform. It now looks like this:

    <?xml version="1.0" encoding="UTF-8" standalone="no"?>
    <?pde version="3.6"?>
    <target name="Eclipse RCP">
        <locations>
            <location includeAllPlatforms="true" includeMode="slicer" type="InstallableUnit">
                <unit id="org.eclipse.equinox.executable.feature.group" version="3.4.1.R36x_v20100823-7M7K7JF90dnJ-WLf3cf4yi"/>
                <unit id="org.eclipse.rcp.sdk.id" version="3.6.0.M20100909-0800"/>
                <repository location="http://download.eclipse.org/releases/helios"/>
            </location>
            <location includeAllPlatforms="true" includeMode="slicer" type="InstallableUnit">
                <unit id="org.eclipse.equinox.executable.feature.group" version="3.4.1.R36x_v20100823-7M7K7JF90dnJ-WLf3cf4yi"/>
                <unit id="org.eclipse.rcp.sdk.id" version="3.6.0.M20100909-0800"/>
                <repository location="http://download.eclipse.org/eclipse/updates/3.6"/>
            </location>
        </locations>
    </target>

8) Re-tried the "site.p2" build, and got the same error.

Interesting, though: now the Target Platform cache does indeed have the cited bundle: org.eclipse.swt.motif.solaris.sparc_3.6.1.v3655c.jar.

9) Tried re-loading the Target Platform, but that didn't fix the problem.
