Editor does not contain a main type

Question

Just going through the sample Scala code on Scala website, but encountered an annoying error when trying to run it.

Here\'s the code: http://www.scala-lang.org/node/

Answer 1

Have faced the similar issue, resolved this by right clicking on the main method in the outline view and run as Java application.

Answer 2

I just had this problem too. The solution is to make sure eclipse created the project as Java project. Just create a new Java project and copy your class into the src folder (and import the eventual dependencies). This should fix the problem.

Answer 3

For me, in Eclipse 3.6, this problem occurs when my main method is not public. I caused the problem by having a main method like this:

static void main(String[] args) 

The dubugger was unable to detect this by itself. I am pretty suprised Eclipse overlooked this.

Answer 4

If it is maven project please check the java file is created under src/main/java

If you are not getting please change the JRE path and create the java files in above folder structure

Answer 5

This could be the issue with the Java Build path. Try below steps :

1. Go to project properties
2. Go to java Build Path
3. Go to Source tab and add project's src folder

This should resolve the issue.

Answer 6
