Hi
I found the solution in this post.
First maven install the jar file.
Then add a dependency with your own chosen groupId, artifactId and versionId to the pom file.
But also add the artifactId to the “Embed-Dependency”.
This should work.
If it doesn’t, have a look at the error. Most likely the reason will be of a missing dependency because the Jar file you uploaded relies also on another jar file. So do the same for that (those) file(s), maven install, add dependency and finally add to the Embed-Dependency.
Kind regards
Dieter
