sbt run won't find external libraries - sql-server

Question

I have mssql as an external library defined like this in my build.sbt.
libraryDependencies ++= Seq(
...
"com.typesafe.slick" %% "slick" % "3.3.2",
"com.typesafe.slick" %% "slick-hikaricp" % "3.3.2",
"com.microsoft.sqlserver" % "mssql-jdbc" % "7.4.1.jre8"
)
Now, in order to run my main object, I do the following
sbt
run
choose the main object
Now, it seems however, that the driver, i.e. the library cannot be found.
java.lang.RuntimeException: Failed to get driver instance for jdbc
...
Caused by: java.sql.SQLException: No suitable driver
I assume it's simply not included in the class path. Any suggestions on how to fix this?
Edit: I use the following way to acquire a database connection.
object DatabaseUtils {
private val cfg: DatabaseConfig[JdbcProfile] = DatabaseConfig.forConfig("database")
def db: JdbcProfile#Backend#Database = cfg.db
}
With this configuration
database = {
profile = "slick.jdbc.SQLServerProfile$"
db {
host = "<IP>"
port = <port>
databaseName = "<dbname>"
url = "jdbc:sqlserver://"${database.db.host}":"${database.db.port}";databaseName="${database.db.databaseName}
user = "<user>"
password = "<pass>"
}
}

I think you miss the Database Driver. From the documentation:
tsql {
driver = "slick.driver.H2Driver$"
db {
connectionPool = disabled
driver = "org.h2.Driver"
url = "jdbc:h2:mem:tsql1;INIT=runscript from 'src/main/resources/create-schema.sql'"
}
}
I don't use Slick, in our project, the driver for MSSQL is com.microsoft.sqlserver.jdbc.SQLServerDriver
