How to convert Java program into jar As Matthew Flaschen commentedanswered, youll need to have a manifest file in your jar, and that should contain Main Class header pointing out which is the main class in the jar to execute. The answer by aioobe perfectly illustrates the simplest way to do this. But instead of doing that always manually, Id recommend that you take a look at a build tool, such as Apache Ant or Maven, but thats probably a bit harder to get started with, which are very commonly used to automate these kind of build sequences. With Ant, youd create a buildfile most commonly named build. Tester. lt target namebuild. Compiles the code and packages it in a jar. Tester. jar. lt fileset dirclasses. Main Class valuecom. Tester. lt manifest. Now, calling ant build would compile your code and package it in Tester. Tester. jar. Note that this example assumes that your sources are in src directory, relative to where you run the command. Youll also need to have Ant installed of course. If you do decide to try out Ant, its official manual will be immensely useful especially the list of Ant tasks which e. Installing Apache Ant Getting Apache Ant The Short Story.
