How to fix 'Error: Could not find or load main class' on scala application in Intellij?

QUESTION

How to fix 'Error: Could not find or load main class' on scala application in Intellij?

Asked 2019-Nov-15 at 08:54

I tried to make a simple scala application, Page Rank, and I can't run it.

The source from which I got the code : https://github.com/abbas-taher/pagerank-example-spark2.0-deep-dive

I created a new scala project in Intellij, the package com.scalaproj and added the code from the source into the scala object, SparkPageRank. I also added the external jars for spark-2.1.0-bin-hadoop2.7, as it said in the tutorial.

I am able to reproduce the error. You just have to mark the directory containing your SparkPageRank object as Sources root in Intellij. (the directory must be in blue)

Right click on the directory -> Mark Directory as -> Sources Root

Hope this work for you !

======= Update after discussion ======

Since this Solution is not working, You have to create a maven project, And add spark and scala dependencies. In github link, I am not sure that your code work without a pom.xml, or build.sbt.

======= Update of 11/13 =======

Code worked with build.sbt

This part is the heart of the PageRank algorithm. In each iteration, the contributions are calculated and the ranks are recalculated based on those contributions. The algorithm has 4 steps: 1- Start the algorithm with each page at rank 1 2- Calculate URL contribution: contrib = rank/size 3- Set each URL new rank = 0.15 + 0.85 x contrib 4- Iterate to step 2 with the new rank.
