Examples with DependencyRunner hudson.DependencyRunner used on opensource projects

Example 1 with DependencyRunner

use of hudson.DependencyRunner in project hudson-2.x by hudson.

the class Trigger method checkTriggers.

            // ignored, only the global setting is honored. The polling job is submitted only if the previous job has
            // terminated.
