triggerPostBuildCallbacks method

@protected void triggerPostBuildCallbacks()

Triggers all callbacks registered in the previous build.

This method must be called once after every build, even if the build threw an exception. Implementations can decide whether call this method immediately after wrapBuild, or schedule it for later. This method will catch any exceptions thrown by the callbacks.
