Eclipse cannot create a Runnable JAR file

Question

I am trying to export a runnable jar file using eclipse. But everytime When I go through the steps suggested by eclipse and the community here, it comes up with following error:

   No resources selected
    Jar export finished with problems. See details for additional information.
       Could not find main method from given launch configuration.

I even tried exporting a simple hello world jar file, but the same error keeps coming up

Any ideas on how I can fix this problem?

Thanks

Got the same issue while exporting one of the jar application.

Solution:

1. Check the run configuration for the Java application
2. If there are multiple run configurations make sure the name of the run configuration is same as the project
