Fix Linux build

[vivainio]

Can't build the project on Linux, probably due to older SDK version (latest ones not available for Windows). .jar file names are probably different (didn't check).

Error (on "gradle build") is

* What went wrong:
Could not resolve all dependencies for configuration ':Examples:testRuntime'.

Aren't you supposed to be on vacation? :)

[vivainio]

Yes, that's why I was fooling around with pointless stuff like Linux build ;-).

What version of the WTK is the latest one on linux? The Oracle pages are seem a bit obfuscated to me, but as far as I could tell the situation is: Windows 3.2, with 3.3 coming up in some time OS X 3.0.x, no planned new releases Linux 2.5.2, no planned new releases?

Am I correct about this?

In gradle it is possible to define new (local) repositories, that act as fallback when a lib is not found in any of the earlier repos. However, supporting different named libraries is bound to get really messy. I have to study if and how that is possible without making the whole build process unmaintainable. The most simple option would be to maintain a separate branch for 2.5.x, 3.0.x and 3.{2,3}. The branches could contain changed build files only, and later changes could be merged into those. This will however, mean some extra work in merging changes back and forth between branches.

[kaiinkinen]

Obviously the comment above assumes that none of the 3.x specific APIs are being used, since in such a case there is a need to branch off all development, and also make sure that the library runs on 2.5.x devices/SDK.
