How to publish multi-module addon to directory?

Hello.

I develop server-side addon -
https://vaadin.com/directory#!addon/subnavigator
. Addon consists of two projects - API and implementation. After publishing zip to directory only one jar is available from vaadin maven repo - implementation, API jar is not available.

My MANIFEST.MF:

Manifest-Version: 1.0 Vaadin-Package-Version: 1 Vaadin-Addon: sub-navigator-1.0.1.jar Vaadin-Dependency: sub-navigator-api-1.0.1.jar Vaadin-License-Title: Apache License 2.0 Implementation-Vendor: com.indvd00m.vaadin Implementation-Title: SubNavigator Implementation-Version: 1.0.1 Zip-file content:

. ├── LICENSE.txt ├── META-INF │ └── MANIFEST.MF ├── README.md ├── src │ ├── sub-navigator-1.0.1-sources.jar │ └── sub-navigator-api-1.0.1-sources.jar ├── sub-navigator-1.0.1.jar └── sub-navigator-api-1.0.1.jar Artifact sub-navigator-api is not available from vaadin repository. After trying build some project with this addon maven throw an exception:

Could not find artifact com.indvd00m.vaadin:sub-navigator-api:jar:1.0.1 in vaadin-addons (http://maven.vaadin.com/vaadin-addons) Addon source code:

https://github.com/indvd00m/vaadin-sub-navigator

How can I fix this?
