Playframework Failed to start with weird kanela.agent.libs.com.typesafe.config.ConfigException

[zhongdj]

It was very weird that the class kanela loader can load application.conf under target folder, but cannot load file under target's child folder, as is shown in the screenshot: target/application.conf loaded fine, but target/local/application-local.conf did not.
