在将Play框架升级到2.4.3后尝试为我的播放应用程序运行ScalaTest测试时出现以下异常
在嵌套套件上调用run时遇到异常 - Guice配置错误：
1）在play.core.ObjectMapperPlugin中找不到合适的构造函数。
Classes must have either one (and only one) constructor annotated with @Inject or a zero-argument constructor that is not private.

答案 0 :(得分：1)
问题的根本原因是ObjectMapperPlugin，你可以通过依赖“com.typesafe.play”%%“play-slick”％“0.8.0”来自“com.typesafe.play”％“play_2.10 “％” 2.3.2" 。 Play框架版本2.4.3使用Scala 2.11。所以你应该排除依赖“com.typesafe.play”％“play_2.10”％“2.3.2”。
您应该将导入更改为：
("com.typesafe.play" %% "play-slick" % "0.8.0")
.exclude("com.typesafe.play", "play-java_2.10")
