Target "clean"/"build" does not exist in the project "javacsv"

[David Alvarez]

Hi guys! I´m making a new aplication for the enterprise that i´m
working now. Is a Java aplication, thats read and write csv files. It
works perfectly on the NeatBeans IDE, but when i´m going to "build" it
or "clean and build" it, the NeatBeans says me this:
Target "clean"/"build" does not exist in the project "javacsv"

What can I do to solve this problem?

Thanks to all.

Sincerelly yours David.
