実装したいこと##

Java環境構築中の初心者なのですが詰まり中
MysqlのデータベースとPlayfreamworkの接続がうまく出来ず困っているところ。
引き続き格闘

環境
MacOs catalina
Java15
sbt 1.4.1
scala 2.13.3
mysql5.6.47

コード##

build.sbt

name := """play-scala-seed"""
organization := "com.example"

version := "1.0-SNAPSHOT"

lazy val root = (project in file(".")).enablePlugins(PlayScala)

scalaVersion := "2.13.3"

libraryDependencies += guice
libraryDependencies += "org.scalatestplus.play" %% "scalatestplus-play" % "5.0.0" % Test
libraryDependencies += jdbc
libraryDependencies += "mysql" % "mysql-connector-java" % "5.6.47"
