Method Detail

decorate

public abstract Launcher decorate(Launcher launcher,
                                  Node node)

Called from Node.createLauncher(TaskListener) to decorate the launchers.

This method should perform node-specific decoration. For job-specific decoration, BuildWrapper.decorateLauncher(AbstractBuild, Launcher, BuildListener) might fit your needs better.

If the implementation wants to do something differently if the launcher is for a build, call Executor.currentExecutor(). If it returns non-null you can figure out the current build in progress from there. Note that Launchers are also created for doing things other than builds, so Executor.currentExecutor() may return null. Also, for job-specific decoration, see BuildWrapper.decorateLauncher(AbstractBuild, Launcher, BuildListener) as well.

Parameters:

launcher - The base launcher that you can decorate. Never null.

node - Node for which this launcher is created. Never null.

Returns:

Never null. Return the 'launcher' parameter to do no-op.

public static ExtensionList<LauncherDecorator> all()
