java - 玩2.4迁移sbt错误

Question

我正在尝试将我的 Play 应用程序从版本 2.3.10 迁移到 2.4(我使用 Java)。我按照 play 主页上的迁移指南进行操作，但 sbt 出现错误。到目前为止我所做的:- 将 build.sbt 中的 scala 版本更改为 2.11.6- 在plugins.sbt中将 Play 版本更改为2.4.0- 将 build.properties 中的 sbt.version 更改为 0.13.8

刷新 build.sbt 后出现以下错误:

似乎 sbt 找不到子项目，但我不知道如何解决这个错误。顺便说一下，该应用程序可以在 2.3.10 上无缝运行。

希望有人能帮助我!提前致谢。

请看一下这个问题的答案

Can't use sbt 0.13.7 with Play subprojects

看起来很相似。如果您当前的 sbt 版本为 0.13.5，那么我很确定这正是您的问题
