Examples of sun.tools.jar.Main

sun.tools.jar.Main
This class implements a simple utility for creating files in the JAR (Java Archive) file format. The JAR format is based on the ZIP file format, with optional meta-information stored in a MANIFEST entry.

    static String SERVICES = "META-INF/services";
    static String contents =
        System.getProperty("test.src") + File.separatorChar + "jarcontents";


    static void run(String ... args) {
        if (! new Main(System.out, System.err, "jar").run(args))
            throw new Error("jar failed: args=" + Arrays.toString(args));
