What we do :

We run Play2 application on Cloudbees and we load a file from '/conf' directory (inside the classpath of the application).

These 2 snippets work in local and at heroku

Play.application().getFile("conf/myfile.json")

and

new File("conf/myfile.json")

However, on Cloudbees, we get FileNotFoundException :

java.io.FileNotFoundException: /var/genapp/apps/..../conf/myfile.json (No such file or directory)

So how to load a file from classpath on Cloudbees?
