opc ua - Milo does not show the version number anymore when I create a standalone assembly

Question

Normally the Milo OPC UA client prints the version number:
Eclipse Milo OPC UA Stack version: 0.5.3

But when I create a single jar (with Maven) then Milo shows:
Eclipse Milo OPC UA Stack version: dev

I mean it is not really a problem but I wonder why it is like this and sure it would be more nice if the correct version number would be shown...

Answer 1

The version numbers are placed in META-INF/MANIFEST.MF files during the build and if your Uber-jar process removed or replaced the manifest with one from another dependency then there is no way for the version to be read any more and it will default to dev.
