clear netbeans cache to create new entity

[thufir]

How do you clear the Netbeans cache from Ubuntu? I'm trying to create a
new "Entity Classes from Database..." but am getting this error:

clients cannot be added because it is already mapped to the
net.bounceme.dur.jpa.Client entity class and the entity is not in current
project source.

so I want to clear the cache, but can't find it. Where is the cache?
