OSGi vs Maven version numbers [message #698401]

Hello.

I am not sure if this is the right forum for this question; if it is not, could you please point me to the right place.

I am currently developing my Virgo based app with Maven and Bundlor. There is a discrepancy between OSGi's idea of a correct version number (ex. 1.0.0.SNAPSHOT) and Maven's (ex. 1.0.0-SNAPSHOT).

I know that the Apache's BND tool automatically manages the dynamic conversion between the two version styles, but this does not appear to be true for Bundlor.

Any idea as to how to manage this?

TIA,
B.

In maven use:

1.0.0.BUILD-SNAPSHOT

or something similar. i.e. instead of "BUILD" you can use "DEV" or a branch name in SCM.

This way you will satisfy both maters Smile

Thanks Dmitry.

I should have actually been more specific. We currently have a Maven savvy release tool which manages all the company's projects, which are not OSGi ones. The tool automatically drops the "-SNAPSHOT" suffix when creating releases to the production environment and it also manages automatic increment of the version numbers.

As such, our OSGi project ought to maintain the 1.0.0-SNAPSHOT convention in order not to break the release tool. Is this possible?

Someone suggested to use something like 1.1.0-SNAPSHOT, where the qualifier in the OSGi sense would be the entire substring "0-SNAPSHOT" and the autoIncremented version number would be the second digit, but is that acceptable?

Thanks again,
B.

OSGi will always interpret a version of 1.1.0-SNAPSHOT to be invalid because the form major.minor.micro.qualifier cannot have a qualifier without both a micro and a '.' between the micro and the qualifier.

The OSGi Alliance are looking at this and have some ideas for a future release, but for now we are stuck with the n.n.n.xxx... format for qualified version numbers.

Thanks Glyn.

I can see how Dmitry's solution could work as an alternative.

I guess so. Dmitry, unlike me, understands Maven.

You could use a property in the pom file that defines the osgi version of the bundle and pass it to the bundlor plugin. This way the ${project.version} and ${project.osgi.version} could be used. One will follow the maven convention and other will follow osgi convention.

Excellent, thanks to both of you!

But if I do what you suggest, Dmitry, then my ${project.version} and ${project.osgi.version} could be anything I like, correct?

Your project version corresponds to the value defined in the <version/> element of the pom. project.osgi.version should be defined in the <properties><project.osgi.version>...</properties> section.
So yes , it can be anything as long as it satisfies osgi versioning schema or major.minor.micro.qualifier.
