没有配置应用程序加载器 [英] No application loader is configured

问题描述

我正在按照尽管我的图书馆中有果汁，但出现以下错误:

And I get the following error, although I have juice included in my library:

libraryDependencies += guice

我对此有适当的帮助.

java.lang.RuntimeException: No application loader is configured. Please configure an application loader either using the play.application.loader configuration property, or by depending on a module that configures one. You can add the Guice support module by adding "libraryDependencies += guice" to your build.sbt.
        at scala.sys.package$.error(package.scala:27)

推荐答案

我遇到了同样的问题.我创建了一个多模块项目，并决定尝试将guice库用于单个模块，因为它是唯一带有play框架的模块.其他模块只是普通的Java项目. 我放

I had the same problem. I created a multimodule project and at some point decided to try to use guice library for a single module as it was the only module with play framework. Other modules are just plain Java projects. I put

libraryDependencies += guice 

该模块.然后问题出现了.即使当我把guice移回去也没有帮助.奇怪的是，如果我使用的话，恢复项目后就可以开始工作

to that module. Then the problem appeared. Even when I moved guice back it didn't help. The strange thing is that after I reverted project started to work if I use

 $sbt run

但是在Intellij Idea中不起作用. 要解决该问题，我必须在我的IDE中重新导入该项目.

but it doesnt work in Intellij Idea. To resolve it I had to reimport the project in my IDE.
