Click a step name to view its log. The step log is
shown below the list of steps. Initially all categories are selected. If
you are viewing a step in a Running job and the step has not completed, you
see a partial log and you may not see all categories.
The log view
is a snapshot taken when you clicked the step. To update the log view for
a running step, click the build tag (at the top, shown as Jobs
>> Tag), then click the step.
