Question

What is the Eclipse equivalent of the NetBeans "Run As Main"?

I have a Java "main" class that contains the start code:

public static void main(String[] args)

Then I have another class foo that has a method bar .

When I am displaying (editing) the main class, and click the run icon, it runs normally. But when I am editing the foo class, and click the run icon, it says:

The selection did not contain any resources that may run on a server

NetBeans always knows to run the main class. Eclipse doesn't. Is there any way to teach Eclipse to play nicely?

Answer 1

Go to Run -> Run Configurations select your project and select Main class and click on Apply button and Run button

This will always run from your selected main class

Answer 2

Open the Preferences and in " Run/Debug " > " Launching " choose " Always launch the previously launched Application " (below " Launch Operation ").

Then, right-click on your Main class and choose " Run-As " > " Java Application ". Now when you edit your other classes and you click the run-button, Main will be launched again.
