[p2-dev] Problem running headless update

Hi,

I'm trying to do a headless update at startup for my product com.example.product, which contains com.,example.feature which contains com.example.plugin. Here's the error I'm getting in my logs, and the code generating it follows that. It seems to be picking up the update site and the IUs ok, but then can't find the artifact.


 (P2Util.java:139) - Got IU from metadata manager com.example.product 1.0.1
 (P2Util.java:139) - Got IU from metadata manager com.example.feature.feature.group 1.0.1

The binary folder in my update site contains "com.example.product.executable.win32.win32.x86_1.0.1"
The artifact.xml inside artifact.jar contains:

- <artifact classifier="binary" id="com.example.product.executable.win32.win32.x86" version="1.0.1">
- <properties size="1">
  <property name="download.size" value="23179" />
  </properties>
  </artifact>

and 

- <artifact classifier="org.eclipse.update.feature" id="com.example.feature" version="1.0.1">
- <properties size="4">
  <property name="artifact.size" value="1087" />
  <property name="download.size" value="1087" />
  <property name="download.md5" value="21511ebfa1cd6769cccf6debd7cfdb4b" />
  <property name="download.contentType" value="application/zip" />
  </properties>
  </artifact>

and an entry for the plugin too.

Here's my code in P2Util:

logger.info( "Status is " + status );
// More complex status handling might include showing the user what
// updates
// are available if there are multiples, differentiating patches vs.
// updates, etc.

Update[] updates = operation.getPossibleUpdates();
for( Update u : updates){
logger.info( "Update is " + u );
}
ProvisioningJob job = operation.getProvisioningJob(null);

}

throw new OperationCanceledException();
}
} catch ( Exception e ){
logger.error( "Exception while trying to get updates", e);

}
return status;
}
