I used CCNet before for my builds and there was a clever plugin to parse errors from NAnt and display it in summary of the build. Now i try to move to Jenkins and have problem with that. I want to have errors displayed in summary of given build but have no idea how to do this. When error in NAnt occur the only solution for now is: go to Console Output and find error manually. Maybe someone knows how to do this?
Depending on what you're building, there are various plugins that may help:
A full list can be found on the Jenkins Plugin page
