Spark 2.4.3 - Scala 2.12.3 - object apache is not a member of package org

I recently updated to Spark 2.4.3 and Scala 2.12.3 (from Spark 2.0.0), and I having issues compiling very simple code (load and show).

My build.sbt with sbt 1.2.8 is:

name := "my-program"

version := "1.0"

scalaVersion := "2.12"

libraryDependencies += "org.apache.spark" %% "spark-core" % "2.4.3"
libraryDependencies += "org.apache.spark" %% "spark-sql" % "2.4.3"
libraryDependencies += "org.apache.spark" %% "spark-mllib" % "2.4.3"

I am developing with Scala for Eclipse, and the jars spark-core_2.12_2.4.3.jar, spark-mllib_2.12_2.4.3.jar, and spark-sql_2.12_2.4.3.jar are linked to my build path (Eclipse shows no error).

I updated Spark, scala, and sbt with homebrew. I don't know if that messes up with how sbt finds the jars?

I tried sbt clean package and sbt package many times, but all I get is:

[error] /Users/me/myproject/src/main/scala/Analysis.scala:5:12: object apache is not a member of package org
[error] import org.apache.spark.sql.SparkSession

I am out of ideas of what to try.

Analysis.scala:

package main.scala

import org.apache.spark.sql.SparkSession
import org.apache.spark.sql.functions._


object Analysis {


   def main(args: Array[String]) {

     // Start Spark session
      val spark = SparkSession.builder().getOrCreate()
      import spark.implicits._
      // Reduce verbosity of output when running in console
      spark.sparkContext.setLogLevel("WARN")

      val df =   spark.read   
      // Format read
      .format("com.databricks.spark.csv")
      .option("header", "true")
      .option("parserLib", "UNIVOCITY")
      .option("inferSchema", "true")
      .json("data/transaction.txt")

      df.printSchema()
   }  

}

The build.sbt was not in the project folder (/Users/me/myproject/), but in the src folder (/Users/me/myproject/src) so when I did sbt package, it never found my build.sbt, and therefore had dependencies problem.
