/**
 * Launches the Wisdom server. This method blocks until the wisdom server shuts down.
 * It uses the {@literal Java} executable directly.
 *
 * @param mojo        the mojo//from   w  w w. j ava2  s.c o  m
 * @param interactive enables the shell prompt
 * @param debug       the debug port (0 to disable it)
 * @param jvmArgs     JVM arguments to add to the `java` command (before the -jar argument).
 * @param destroyer   a process destroyer that can be used to destroy the process, if {@code null}
 *                    a {@link org.apache.commons.exec.ShutdownHookProcessDestroyer} is used.
 * @throws MojoExecutionException if the Wisdom instance cannot be started or has thrown an unexpected status
 *                                while being stopped.
