Unresolved dependency with xgboost library in scala [duplicate] - scala

Question

This question already has answers here:
sbt build failed for spark scala with xgboost
(2 answers)
Closed 5 years ago.
I've added my xgboost jar files in the library and modules in my project structure. (I built the jar files from source successfully as mentioned in the documentation). I can't seem to be able to resolve the dependency for it. I've tried to run it with the dependency included in the build sbt file and with it taken out (since the jars are already included in the library and dependencies via the project structure). Both seem to be failing. Is this some sort of a compatibility issue? I am running scala 2.11.8 and spark 2.1.0. My dependencies are included in a sequence as follows:
"ml.dmlc" %% "xgboost4j" % "0.7", "ml.dmlc" %% "xgboost4j-spark" % "0.7"
I seem to be missing something but I am not sure what. Any ideas?
I tried to publish the jar as suggested but I get the following error:
sbt.ResolveException: unresolved dependency: ml.dmlc#xgboost4j_2.11;0.7: not found

Answer 1

The dependency should only have one % there.
"ml.dmlc" % "xgboost4j" % "0.7", "ml.dmlc" % "xgboost4j-spark" % "0.7"
