scala:console is worse than Scala's own REPL?

Question

Using maven-scala-plugin I can run Scala console with all dependencies as:

mvn scala:console

However, what I get is much more poor REPL than Scala's own one (the one you get when run scala without arguments). E.g. it misses auto-completion and history, arrow keys just print their code (instead of moving cursor), etc.

Is it known issue or just a misconfiguration in my setup? If first, what are alternatives to scala:console (i.e. REPL with all dependencies and compiled code)?

Plugin configuration in my pom.xml:

<plugin>
    <groupId>org.scala-tools</groupId>
    <artifactId>maven-scala-plugin</artifactId>
    <version>2.15.0</version>
    <executions>
      <execution>
        <goals>
          <goal>compile</goal>
          <goal>testCompile</goal>
        </goals>
        <configuration>
          <args>
            <arg>-make:transitive</arg>
            <arg>-dependencyfile</arg>
            <arg>${project.build.directory}/.scala_dependencies</arg>
          </args>
        </configuration>
      </execution>
    </executions>
</plugin>

Answer 1

the version org.scala-tools:maven-scala-plugin:2.x of the plugin is deprecated/dead (due to EOL of scala-tools.org, maven3 convention,...).

Try

    <groupId>net.alchim31.maven</groupId>
    <artifactId>scala-maven-plugin</artifactId>
    <version>3.2.0</version>

(Note : I'm the author of both plugins).

Answer 2

It's interesting how asking questions on SO makes you think in another direction and find answers yourself. It turns out I missed error message on REPL start:

Failed to created JLineReader: java.lang.NoClassDefFoundError: scala/tools/jline/console/completer/Completer Falling back to SimpleReader.

Which quickly leads to solution - one just needs to add JLine to dependency list:

<dependency>
  <groupId>org.scala-lang</groupId>
  <artifactId>jline</artifactId>
  <version>2.9.0-1</version>
</dependency>
