import org.apache.spark.sparkcontext import org.apache.spark.sparkcontext._ import org.apache.spark.sparkconf import org.apache.spark.sql._ import com.databricks.spark.avro._  object tester {   def main(args: array[string]) {     val conf = new sparkconf().setappname("simpleapplication").setmaster("local")     val sc = new sparkcontext(conf)      // creates dataframe specified file     val df = sqlcontext.load("episodes.avro", "com.databricks.spark.avro")   } }

"sbt package" not include dependencies, try sbt-assembly instead.
