Trying to update a dependency

Development IDE & Build
,

Hi there,
as I recently managed to upgrade my openhab to 2.x (2.2 currently), I’d like to migrate my diyonxbee binding to be a native openhab 2 binding (the old version doesn’t work well in oh2). My very first problem is that I’d like to add a 3rd party dependency, which on it’s own depends on rxtx which, as far as I read, is provided in openhab2 via <feature>openhab-transport-serial</feature>. The library I want to use is not a OSGI bundle.

The question is, how I can resolve this.

  • Do I manually add the OSGI descriptors to that bundle? (would that mean I have to fork it?)
  • Or could I use the wrap mechanism?

Thanks in advance for any guidance.

It should be enough to add the dependency to the binding-pom with scope default. It then gets embedded and you do not have to take care of the feature (except adding the serial feature).

I just tried that but It doesn’t work - I might have a misunderstanding. Would anybody mind lookging at my attempt (github) ?

My fault. Scope should be compile. What exactly do you mean by “not working”? Please show the maven log

trying with scope compile gives me:

Isn’t there anybody out being able to help me? To better explain my problem: I want to use a non-osgi library that depends on rxtx which seems to be provided by openhab’s transport-serial module. I just don’t manage to simply get the build for that dependency working.

thanks

I’m not 100% sure it works, but at least it removes the dependency to org.rxtx/rxtx/2.2 and compiles (after I fixed a wrong null-annotation).
