How to Fix Eclipse Error: The Selection Cannot Be Launched

This tutorial demonstrates the Eclipse error The selection cannot be launched, and there are no recent launches in Java.

Eclipse The selection cannot be launched Error

When using Eclipse, an error The selection cannot be launched can occur. While we have a selection of classes and no class has the main method, this error will occur in Eclipse because Eclipse will only run the set of classes or an application when it finds the main class.

Eclipse needs to see the main method in one of the project files. Otherwise, it cannot run the application.

The main method should be properly defined as below.

public static void main(String[] args)

Without a proper definition of the main method, Eclipse will throw the The selection cannot be launched. Here is an example.

package delftstack;

public class Example {
  public static void main(String[] args[]) throws IOException {
    System.out.println("This is Delftstack.com");
  }
}

The code above will throw The selection cannot be launched because the main method is not properly defined. Here is the correct version of the code.

package delftstack;

public class Example {
  public static void main(String[] args) throws IOException {
    System.out.println("This is Delftstack.com");
  }
}

The [] is given to the String keyword in the main method statement. Now, this code will work properly.

See output:

This is Delftstack.com
