Create a java executable with Eclipse

Question

This is a totally newbie question. I'm running Eclipse on Ubuntu. I created a test project that I want to compile to an executable (whataver the linux equivalent is of a Windows .exe file). Here's the contents of my program:

public class MyTest {
    public static void main(String[] args) {

        System.out.println("You passed in: " + args[0]);

    }
}

I want to know how to compile it and then how to execute it from the command line.

Thanks!

Answer 1

You need to create an executable JAR file. Steps will follow shortly.

Right click on the project and select JAR file under Export.

Enter the path where you want it to be saved. The example here is of Windows. Change according to your platform.

Click Next.

Edit the Main Class field by browsing and selecting the location of your class that contains the main method.

Run it

To run the JAR file, open up a shell or command prompt and execute the following command:

java -jar path/to/test.jar

Answer 2

In Eclipse, choose file then export, and you will have to choose runnable jar. Also, you will be prompted to select the main class, MyTest in your case.
