I've just tried hudson integration in netbeans 7 and I found few problems regarding user input when I'm connected to some external hudson instance.
1/ I'm not asked for authentication at the begining, therefore I'm connected to hudson instance as anonymous and see only those jobs which are not restricted. I'm asked for authentication only on some events like triggering build (if anonymous can't run the build) or when I try to access workspace of some job. After this I have full access to all jobs according to my permissions.
2/ I cannot run builds with parameters - some builds are using parameters and when I try to run those from netbeans, it doesn't do anything. I would expect netbeans to ask for parameter values similar way as hudson is doing it. I've tried to copy the job in hudson and remove all parameters, running this copy from netbeans works without problems.
#1 is a duplicate of bug #167585. In the future please file separate reports for each distinct issue you encounter.
For #2 - not surprising, though I doubt I will spend time implementing support for a relatively marginal use case. Patches welcome.
