Spark / scala : publish a single fat jar with sbt - scala

Question

I am trying to deploy a single Fat Jar from a spark/scala project to a private nexus repository. The publish works fine but I get a large amount of files instead of one single assembly Jar :
*-assembly.jar
*-assembly.jar.md5
*-assembly.jar.sha1
*-javadoc.jar
*-javadoc.jar.md5
*-javadoc.jar.sha1
*-source.jar
*-source.jar.md5
*-source.jar.sha1
*.jar
*.jar.md5
*.jar.sha1
*-pom.jar
*-pom.jar.md5
*-pom.jar.sha1
My built.sbt is :
name := "SampleApp"
version := "0.1-SNAPSHOT"
scalaVersion := "2.12.14"
ThisBuild / useCoursier := false
libraryDependencies ++= Seq(
"com.github.scopt" %% "scopt" % "4.0.1",
"org.apache.spark" %% "spark-sql" % "3.1.1" % "provided"
)
resolvers ++= Seq(
"confluent" at "https://packages.confluent.io/maven/"
)
assembly / assemblyMergeStrategy := {
case PathList("META-INF","services",xs # _*) => MergeStrategy.filterDistinctLines
case PathList("META-INF",xs # _*) => MergeStrategy.discard
case "application.conf" => MergeStrategy.concat
case _ => MergeStrategy.first
}
assembly / assemblyExcludedJars := {
val cp = (assembly / fullClasspath).value
cp filter { f =>
f.data.getName.contains("hadoop-hdfs-2")
f.data.getName.contains("hadoop-client")
}
}
assembly / artifact := {
val art = (assembly / artifact).value
art.withClassifier(Some("assembly"))
}
assembly / assemblyJarName := s"${name.value}-${version.value}.jar"
addArtifact(assembly / artifact, assembly)
resolvers += ("Sonatype Nexus Repository Manager" at "http://localhost:8081/repository/app/").withAllowInsecureProtocol(true)
credentials += Credentials("Sonatype Nexus Repository Manager", "localhost:8081", "user", "pass")
publishTo := {
val nexus = "http://localhost:8081/repository/app/"
if (isSnapshot.value) {
Some("snapshots" at nexus + "test-SNAPSHOT")
} else
Some("releases" at nexus + "test-RELEASE")
}
Is there a way to filter files with sbt before the publish in order to get only the *-assembly.jar ? Thanks a lot.

Answer 1

This should disable the publish of unnecessary files in my case :
publishArtifact in (Compile, packageBin) := false
publishArtifact in (Compile, packageDoc) := false
publishArtifact in (Compile, packageSrc) := false
