Example 2 with LocalLauncher

use of hudson.Launcher.LocalLauncher in project hudson-2.x by hudson.

the class Channels method newJVM.

/**
     * Launches a new JVM with the given classpath, establish a communication channel,
     * and return a {@link Channel} to it.
     *
     * @param displayName
     *      Human readable name of what this JVM represents. For example "Selenium grid" or "Hadoop".
     *      This token is used for messages to {@code listener}.
     * @param listener
     *      The progress of the launcher and the failure information will be sent here. Must not be null.
     * @param workDir
     *      If non-null, the new JVM will have this directory as the working directory. This must be a local path.
     * @param classpath
     *      The classpath of the new JVM. Can be null if you just need {@code slave.jar} (and everything else
     *      can be sent over the channel.) But if you have jars that are known to be necessary by the new JVM,
     *      setting it here will improve the classloading performance (by avoiding remote class file transfer.)
     *      Classes in this classpath will also take precedence over any other classes that's sent via the channel
     *      later, so it's also useful for making sure you get the version of the classes you want.
     * @param vmb
     *      A partially configured {@link JVMBuilder} that allows the caller to fine-tune the launch parameter.
     *
     * @return
     *      never null
     * @since 1.361
