Now with 2.3, I get the following exception when running the app:\r\n\r\n~~~scala\r\nakka.ConfigurationException: Could not start logger due to \r\n[akka.ConfigurationException: Logger specified in config can't be loaded \r\n[akka.event.slf4j.Slf4jLogger] due to [java.lang.ClassNotFoundException: akka.event.slf4j.Slf4jLogger]]\r\n~~~\r\n\r\nThis prevents the app from launching, and the only solution is to disable the event logger.\r\nClasspath-wise everything seems fine.\r\n\r\nRunning tests works fine.\r\n\r\nWe are using `application.conf` only on staging and production servers. Locally every sub-project has a `reference.conf` and we are running the app with `-Dconfig.file=dev.conf`, where the dev.conf includes the reference.conf. When I rename `reference.conf` to `application.conf` everything seems to work fine.\r\n"},"comment":{"url":"https://api.github.com/repos/playframework/playframework/issues/comments/73640757","html_url":"https://github.com/playframework/playframework/issues/3106#issuecomment-73640757","issue_url":"https://api.github.com/repos/playframework/playframework/issues/3106","id":73640757,"user":{"login":"dragisak","id":800802,"avatar_url":"https://avatars.githubusercontent.com/u/800802?v=3","gravatar_id":"","url":"https://api.github.com/users/dragisak","html_url":"https://github.com/dragisak","followers_url":"https://api.github.com/users/dragisak/followers","following_url":"https://api.github.com/users/dragisak/following{/other_user}","gists_url":"https://api.github.com/users/dragisak/gists{/gist_id}","starred_url":"https://api.github.com/users/dragisak/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/dragisak/subscriptions","organizations_url":"https://api.github.com/users/dragisak/orgs","repos_url":"https://api.github.com/users/dragisak/repos","events_url":"https://api.github.com/users/dragisak/events{/privacy}","received_events_url":"https://api.github.com/users/dragisak/received_events","type":"User","site_admin":false},"created_at":"2015-02-10T03:59:41Z","updated_at":"2015-02-10T03:59:41Z","body":"I see this with Play 2.3.7 Even when I remove all web plugins.\r\n\r\nI have only `addSbtPlugin(\"com.typesafe.play\" % \"sbt-plugin\" % \"2.3.7\")` in my plugins.sbt\r\n"}}
