Hi Daniel,
I saw unique -plugin -id requires jenkins core
1.615 . We have an older Jenkins version.
I've created my own plugin to keep this info , by extending JobProperty class.
But now I have another question related to the field that should be field in position .
right now in the ob configuration page I can see the elements if the Order bellow:
1- Project Name
2- Descripton
3- discard Old builds
4- Block Build if certain jobs are runninc
5- Project Number(ID) - this was added by me
I would like to change a little bit the order , to have Project Number(ID) on the second position, just bellow the Project Name

Thank you !
