I'am using Jenkins now, and sometimes the build jobs stucked and with red progress bar. I am really confused how jenkins determine the color of the progress bar.
When it is blue? and when it become red?
Does anyone have ideas?
| The progress bar is normally empty, filling with blue while a build in progress.
The amount of time it takes the progress bar to fill is based on the estimated job duration. This estimate is generally based on the average duration of the last few successful builds.

Why are there two kinds of jobs for Jenkins, both the multi-configuration project and the free-style project project?
