jenkins.DailyCheck
All Implemented Interfaces:
ExtensionPoint, Runnable
@Extension @Restricted(org.kohsuke.accmod.restrictions.NoExternalUse.class) @Symbol("updateCenterCheck") public final class DailyCheck extends AsyncPeriodicWork
Implements a daily update check for update sites and DownloadService.Downloadables that are due. Note that this does not mean that update center information is at most 24 hours old, but rather 24-48 hours. Downloadables are by default due every 24 hours, as are update sites. This check runs every 24 hours, but only updates what is already due, i.e. older than 24 hours. So this ensures that update site information is never older than 48 hours.

  • Constructor Details

      public DailyCheck()

  • Method Details

    • getRecurrencePeriod

      public long getRecurrencePeriod()
      Description copied from class: PeriodicWork
      Gets the number of milliseconds between successive executions.

      Hudson calls this method once to set up a recurring timer, instead of calling this each time after the previous execution completed. So this class cannot be used to implement a non-regular recurring timer.

      IOW, the method should always return the same value.

      Specified by:
      getRecurrencePeriod in class PeriodicWork

    • getInitialDelay

      public long getInitialDelay()
      Description copied from class: PeriodicWork
      Gets the number of milliseconds til the first execution.

      By default it chooses the value randomly between 0 and PeriodicWork.getRecurrencePeriod()

      Overrides:
      getInitialDelay in class PeriodicWork

    • execute

      protected void execute(TaskListener listener) throws IOException, InterruptedException
      Description copied from class: AsyncPeriodicWork
      Executes the task.
      Specified by:
      execute in class AsyncPeriodicWork
      Parameters:
      listener - Output sent will be reported to the users. (this work is TBD.)
      Throws:
      IOException - The caller will record the exception and moves on.
      InterruptedException - The caller will record the exception and moves on.
