Importing classes into Scala worksheet

Question

In my scala worksheet test.sc I define :

import com.tradedata.VolatilityInstance

test.sc exists at src/main/scala

In location src/main/scala I define :

package com.tradedata

class VolatilityInstance(intervalLength: Int, volatility: Double, beginDate: String, endDate: String) {

  override def toString: String = {
    this.beginDate
  }

}

The filename for this class is VolatilityData.scala

VolatilityData.scala exists at level src/main/scala/com/tradedata

When I attempt to run the worksheet I receive error :

Error:(1, 16) object VolatilityInstance is not a member of package com.tradedata
import com.tradedata.VolatilityInstance

If i define a new Scala object :

import com.tradedata.VolatilityInstance

object Tester extends App {

}

Tester object runs without issue.

I've tried re-building the project, invalidating the caches and restarting IntelliJ but cannot fix.

Is this a bug with the Scala worksheet ? How to import other classes into the Scala worksheet ?

Answer 1

I've tested your case in IntelliJ IDEA 2019.2.3 (Ultimate Edition) with Scala plugin 2019.2.28

Open test.sc, click Scala worksheet settings and change Run type from REPL to Plain.

Answer 2

In Worksheet Settings check Build project before run
