Unable to build eclipse application repository or site with patch features

[GorakhSaste]

This issue is based on https://bugs.eclipse.org/bugs/show_bug.cgi?id=389698

The feature patches are required to introduce new features, since to support the specific plugins to provide customers with the feature patches. unable to create the patch repository for patch feature using maven tycho.

I have created the sample application to reproduce this issue. (attached tycho-patch-feature-example.zip)
In this sample application, com.example.tycho.feature.patch contains feature.xml which will contain below code is added.

<import feature="com.example.tycho.feature" version="1.0.0.qualifier" patch="true"/>

tycho-patch-feature-example.zip

Patch feature is built with maven Tycho, but while create site with com.example.tycho.update.patch for the patch feature then below errors getting.

If it is crucial to your business you can find dedicated support options for Tycho here:

I need to understand that, latest Maven Tycho is support for the build eclipse application repository or site with patch features or not.
