Subject Re: OSGi and Git - what release process, how many repos?
Date Mon, 11 Aug 2014 12:53:05 GMT
yes it is ! On my current project I have some definitions like this :

  * component. Each component covers a functionality of my project and
    can be composed by several bundles (typically : one bundle for data
    model and one bundle for UI). Each component has its own versioning
    policy and so its own git repository. Each component version is a
    git tag.

  * distribution : this is the final application delivery. It is
    composed by set of versioned component + the OSGI container (virgo
    currently) + a python installer to help the configuration of the
    application + some others things I forgot ;)

Currently I have a custom python tool to define the distribs (ie : 
versions of components for each distrib) and build it from the 
components git repositories...

You can have a look on that tool here : 

At the time I wrote this distribution tool I didn't see any other tool 
to help me manage and build project dispatched through many git 
repositories. If you know any tool covering that need I'll be happy to 
test it...
