    The packageinfo files are in the source tree because they're source files,
    and provide metadata for the package.
    You can also use a package annotation on package-info.java, which puts a
    Class Retention annotation on the packages package-info.class.
    
    Examples:
    
    
https://github.com/apache/felix/blob/trunk/dependencymanager/org.apache.felix.dependencymanager.annotation/src/org/apache/felix/dm/annotation/api/packageinfo
    
    https://github.com/apache/felix/blob/trunk/converter/
    converter/src/main/java/org/apache/felix/converter/dto/package-info.java
    
    (Requires provided / compileOnly dependency on the osgi annotation bundle).

> The OSGI versions in the current distributions are not being correctly 
> generated.  OSGI relies on package version numbers following semantic version 
> properly for correct resolution.  
> Current version numbers have been generated from the maven version. This has 
> lead to new minor version increases for packages that have no API changed; it 
> has also concealed   major (breaking) changes to several packages since 1.0.
> I have created two branches that address the issue.
> Both add the bundle:baseline goal to the verify phase of the build. 
> The also both have packageinfo files added to every package, containing the 
> package version. These are picked up by the bundle manifest generator, and 
> are used if no explicit version is given in the "Export-Package" command. 
> Both branches bump the major version number for packages with any minor 
> changes to 2.0.0.  This makes the bundle correct, but does not fix improper 
> import declarations made by users of earlier bundles.   
> One branch uses the version number  from the oldest version that has no 
> changes when compared to HEAD, and which has not had any breaking changes 
> since 1.0.0.  This will fail the build because version numbers should be 
> increasing, and may cause issues if an importing bundle uses a range that 
> requires an identical, but higher numbered version of the package
> The other branch uses version 1.14.0 for all packages with no major changes. 
> A third alternative, which I didn't add, is to just set all packages be 
> version 1.14.0, and just bump major versions when required going forward. The 
> bulk of the major changes happened a good few versions back,  so it's not as 
> bad as it could be. 
> If you have a preferred option, I can create a pull request on Github
