Publish a runnable JAR file

- [Instructor] So let's say you built an app with Java, and you want to distribute it as a runnable file. So here's an app that we built in a previous chapter, where you can type in your name, hit the button, and then you see Hi in the label. Let's look at exporting this as a runnable JAR file. Close this out, head back over to Eclipse, and then I'm going to show the project navigator by clicking these two windows right here, this button on the left. And then I'm going to select my project, and I'm going to use the File menu to go to File, Export. And what I want to export is under Java. I want to export a runnable JAR file. So hit Next after selecting that. And then we'll need to choose a launch configuration, so click the drop-down, choose your project. Then we need to choose an export destination. I'll browse to the Desktop. I'll just go in there with the shortcut Command + D. And I'll save this as Hello, and then I'll hit Save. And here, under Library handling, you can choose if you want to extract the required libraries into generated JAR, or if you want to package them into the generated JAR, or if you want to copy them into a sub-folder. Since we want one executable file, I'm just going to choose that top option, and then I'm going to hit Finish. Let's tab back over to Finder, and there's our JAR file. So at this point, I should be able to just double-click on the file and have it open up and run the application, just like any other native app in my operating system. And there we go, so we can publish a runnable JAR file by simply exporting our project.
