[pde-dev] how to generate container feature in pde build

[Jacek Pospychała <jacek.pospychala@xxxxxxxxx>]

hi,
I remember this was discussed already, but can't google it so please help! :-)

I want to build two features in one pdebuild run.
Until now I was solving this by defining many calls in allElements target:

<target name="allElements">
        <ant antfile="${genericTargets}" target="${target}">
             <property name="type" value="${topLevelElementType1}" />
             <property name="id" value="${topLevelElementId1}" />
         </ant>
        <ant antfile="${genericTargets}" target="${target}">
             <property name="type" value="${topLevelElementType2}" />
             <property name="id" value="${topLevelElementId2}" />
         </ant>
    </target>

unfortunately, now I discovered the downside of this approach is that when using p2.gathering=true, the generated metadata contains only the last element :-(

The other way that I read of somewhere, was to generate container feature during the build. I tried

<target name="preSetup">
...
<eclipse.generateFeature featureId="tarara.container.feature" buildDirectory="${buildDirectory}" featuresList="topLevelElement1,topLevelElement2" />

I can see that feature is generated correctly. But later, during the fetch, pde build is failing to fetch top level feature:
fetchElement:
    [mkdir] Created dir: /disk2/hudson/jobs/org.mozilla.xulrunner.7_3/workspace/build/plugins
[eclipse.fetch] Missing directory entry: feature@xxxxxxxxxxxxxxx.feature.
[eclipse.fetch] feature@xxxxxxxxxxxxxxx.feature has not be fetched.

R36_RC4/plugins/org.eclipse.pde.build_3.6.0.v20100603/scripts/genericTargets.xml:59: The following error occurred while executing this line:
java.io.FileNotFoundException: /disk2/hudson/jobs/job/workspace/build/fetch_tararara.container.all.feature.xml (No such file or directory)

So feature is already there, and there's no need to fetch it. Altough topLevelElement1 and topLevelElement2 need to be fetched.
So what else I need to do? Use eclipse.fetch?

At last I can create container feature in CVS but this is lame :-)

thanks
