I'm currently trying to get Netbeans with the Git plugin working.
If I want to clone my git repository from within Netbeans I get the error message:
reject hostKey: [repository url]
and the cloning aborts.
What does this mean and how do I fix it?
You need to check what user is running NetBeans, and then make sure your ssh private and public keys (id_rsa and id_rsa.pub) are in the associated HOME/.ssh of that user.
Note that on Windows, HOME isn't defined by default, so you need to set that variable before running Netbeans.
