Apache flink Kafka Connector not found

I'm fairly new to flink/Java/Scala so this might be a non-question but any help is appreciated. I haven't been able to find an example that uses the Flink Kafka connector with Flink 1.13 (and works for me).

My project is here: https://github.com/sysarcher/flink-scala-tests

I want to I'm unable to use FlinkKafkaConsumer (link) which I want to try out.

I'm using IntelliJ Idea. The project was generated from the tutorial on Flink's website

The First problem seemed to be the provided scope as suggested here: https://stackoverflow.com/a/63667067/3760442 ... Now, DataStream API (and the example) seem to work.
The current problem is that I'm not able to use the Kafka connector which I'm looking to try out.

The following link was used to generate the project: https://ci.apache.org/projects/flink/flink-docs-release-1.13/docs/try-flink/datastream/#how-to-follow-along

Error Encountered

$ mvn clean compile
[INFO] ...
[WARNING] Multiple versions of scala libraries detected
[ERROR] /hide/abs/path/github/flink-stuff/frauddetection/src/main/scala/spendreport/FraudDetectionJob.scala:42: error: not found: type FlinkKafkaConsumer

[ERROR]                             ^
[ERROR] one error found

UPDATE:

One problem was the missing import statement:

import org.apache.flink.streaming.connectors.kafka.FlinkKafkaConsumer

I can build the artifacts using mvn clean compile but IntelliJ still complains with the following error:

/long/path/flink-stuff/frauddetection/src/main/scala/spendreport/FraudDetectionJob.scala:30:35
object connectors is not a member of package org.apache.flink.streaming
import org.apache.flink.streaming.connectors.kafka.FlinkKafkaConsumer

Solution

It turns out the problem was with IntelliJ's indexing (or something, I'm not sure). I pressed CTRL+SHIFT+A and typed Reload All Maven Projects. Thereafter, the build was successful.

It seems sometime IntelliJ does not works well for index, perhaps you could choose mvn -> reimport project from the context menu, if it still not work, perhaps you might try remove the .idea and .iml file and re-open the project again.
