Question

我有一个使用Scala的Play应用程序。当前工作版本使用：

游戏框架：2.5.18 斯卡拉（Scala）：2.11.7 Sbt：0.13.11

但是当我将以上内容升级到以下版本时，一切都会中断：

游戏框架：2.6.17 Scala：2.12.6 Sbt：1.1.6

一切都中断了，我的意思是当我在IDE（Intellij）中重新加载sbt时，它失败并显示以下错误：

如果我仅在终端中运行sbt compile，则会出现以下错误：

[info] Loading project definition from /project
[error] /project/Grunt.scala:14:9: Java class java.lang.Process is not a value
[error]         Process("grunt build", base).run

Project loading failed: (r)etry, (q)uit, (l)ast, or (i)gnore?

关于可能出了什么问题以及如何解决它，我确实全神贯注。版本之间是否存在不兼容问题？是因为某些东西被弃用了吗？我真的不能告诉...谷歌搜索也没有帮助。

任何有关如何解决此问题的建议，或者可能出了什么问题，将不胜感激！

更新看着编译错误，我最初以为我已经导入了Java Process，但这是文件中的import部分，给出了编译错误：

import java.net.InetSocketAddress

import play.sbt.PlayRunHook
import sbt._

应该注意的是，所有这些在以前都运行良好。唯一的更改是升级Scala / Play / SBT

Answer 1

您导入了错误的Process。

您已导入java.lang.Process，而您需要scala.sys.process.Process

如sbt 1.0.0 release notes

中所述

sbt.Process和sbt.ProcessExtra被删除。请改用scala.sys.process

升级Scala，Play和SBT的问题
