it's not necessary to build a "java-tron" jar.
What u need is FullNode.jar or SolidityNode.jar

[DorianRust]

setting shadowJar.enabled = true can generate java-tron.jar. Not need a special version number.

What I needed was to include java-tron as a lib, I don't care about the the distrib jar (=same lib, different bundle)

Ok thanks, I'm not sure this was working 6 months ago ... I close this request anyway.
