PlayFramework ~run strange error

Question

Am using Play 2.1.0, Everything was fine all of a sudden I get this strange error (Attached snapshot) this is during when i execute ~run from play console.

Environment : Windows 7, IntelliJ12, Mysql, JDK 1.6

Snapshot :

Error statement: 'is not a directory so descendants can not be called'

Answer 1

The problem occurs if another process has locked /logs/application.log. E.g. if you open the log file in Word and then run play, you will see the error

Answer 2

Quit your console or whatever you are using to start your application. Delete application.log file. Go to your console screen again. Finally retype run and hit enter.

This file will be regenerated and error will be gone.
