How do you deliver the snapshot created by a build to the stream?

We are using EE dependency builds which do not have the post-build option to deliver the snapshot.

I wrote an ant task that uses the api to do the deliver, but nothing happens  --  no errors, no messages, no delivery.  With the CLI you have to add -o option to make it work.  Do I need something special using the API to duplicate the -o option?

This will make the CLI do the delivery:

 <!-- ScmDeliverSnapshot Macro -->
 <macrodef name="ScmDeliverSnapshot">
  <attribute name="property" default="scm.property.output.ScmDeliverSnapshot"/>
  <attribute name="workspace"/>
  <attribute name="stream"/>
  <sequential>
   <local name="scm.cmd"/>
   <Scm property="scm.cmd"/>
   <local name="scm.property.output.ScmDeliverSnapshot"/>
   <exec executable="${scm.cmd}" failonerror="true" outputproperty="@{property}">
    <arg value="--config"/>
    <arg value="${dir.scc}"/>
    <arg value="--non-interactive"/>
    <arg value="deliver"/>
    <arg value="-o"/>
    <arg value="-v"/>
    <arg value="-s"/>
    <arg value="@{workspace}"/>
    <arg value="-t"/>
    <arg value="@{stream}"/>
   </exec>
   <ac:propertycopy name="scmTemp" from="@{property}" override="true"/>
   <echo level="verbose">Scm: @{property}:</echo>
   <echo level="verbose">${scmTemp}</echo>
  </sequential>
 </macrodef>

Here's the deliver code which does not deliver:

// Search for stream
IWorkspaceSearchCriteria criteria = IWorkspaceSearchCriteria.FACTORY.newInstance().setKind(IWorkspaceSearchCriteria.STREAMS);
criteria.setExactName(getStreamName());
List<IWorkspaceHandle> streamWorkspaceHandles = wsManager.findWorkspaces(criteria,Integer.MAX_VALUE,null);

// Verify one stream
if (streamWorkspaceHandles.size() == 0) {
  throw new TeamRepositoryException(NLS.bind(CommonMessages.COMMON_NOTFOUND_STREAMNAME,getStreamName()));
}

// Connect to stream
IWorkspaceHandle streamWorkspaceHandle = streamWorkspaceHandles.get(0);
IWorkspace streamWorkspace = (IWorkspace) repo.itemManager().fetchCompleteItem(streamWorkspaceHandle,IItemManager.DEFAULT,null);
IWorkspaceConnection streamWorkspaceConnection = wsManager.getWorkspaceConnection(streamWorkspace,null);

// Get change report
syncReport = wsConnection.compareTo(streamWorkspaceConnection,WorkspaceComparisonFlags.INCLUDE_BASELINE_INFO,Collections.EMPTY_LIST,null);

// Deliver to stream
for (Object changeHandle : syncReport.outgoingChangeSets()) {
  // Check IChangeSetHandle
  if (!(changeHandle instanceof IChangeSetHandle)) {continue;}

  // Get change set details
  IChangeSet changeSet = scmChangeset.getSnapshotChangeset((IChangeSetHandle) changeHandle);
  IComponentHandle componentHandle = changeSet.getComponent();
  
  // Deliver pending change
  wsConnection.deliver(streamWorkspaceConnection,syncReport,syncReport.outgoingBaselines(componentHandle),syncReport.outgoingChangeSets(componentHandle),null);
}

The syncReport.outgoingBaselines() = 3 before and after code executes.  Completes without any message saying why deliver failed.
