On GUI platforms that support it, you can also launch this application by double-clicking on the JAR file. You do not need to add it to your CLASSPATH or list the name of the main class. This project includes all the Java source code, as well as a complete Ant Jarbundler build script that you can use to make. Today, I just released the source code for a small but complete 'Java on Mac OS X' project.

You can now copy the JAR file anywhere and run it the same way. Ive even released some Ant build scripts to demonstrate how to build a Java application on Mac OS X using the Ant Jarbundler task. Then give the following commands: C:> javac HelloWorld.java C:> jar cvmf manifest.stub hello.jar HelloWorld.class C:> java -jar hello.jar Hello, World of Java C:> In a file called, say, manifest.stub, and assuming that you want to run the program HelloWorld. Create a one-line entry like this, noting that the attribute fields are case-sensitive and that the colon must be followed by a space: Main-Class: HelloWorld The JarBundler site has the following to say: When the JarBundler ANT task is used under Windows or Linux, a copy of the JavaApplicationStub must be supplied.

How does it know which class to run? You must tell it. In this case, it will also find classes it needs to load from within the same JAR file. The java command has a -jar option that tells it to run the main program found within a JAR file. SolutionĬreate a JAR file with a Main-Class: line in the manifest run the program with the java -jar option. You can add an icon resource, set various macOS native look-and-feel bells and whistles, and maintain your application bundles as part of your normal build and release cycle. You want to distribute a single large file containing all the classes of your application and run the main program from within the JAR. JarBundler is a feature-rich Ant task which will create a macOS application bundle from a list of Jar files and a main class name. A recent MacOSX Java update broke the current jarbundler task in build.xml (probably due to the classpath changes in.
