eclim org.eclipse.core.runtime.CoreException: Cannot create file, access denied: /path /to/my_project

Question

• I installed eclim
• Opened eclimd(like as skript ./eclimd).
• Then tried create a new project in vim using command: :ProjectCreate /path/to/my_project -n java and get this error.

org.eclipse.core.runtime.CoreException: Cannot create file, access denied: /path /to/my_project. while executing command (port: 9091): -editor vim -command project_create -f "/p ath/to/my_project" -n java

Can somebody know reason of this error in eclim and how to fix it?
