Question

Absolute Scala初学者在这里。我在macOS X中安装了scala 2.12.1。

我正在尝试设置here

中的样本computer-database Play-Slick示例

我cd进入计算机数据库后，我运行sbt run，结果导致此错误：

error: not found: value PlayKeys "PlayKeys.playOmnidoc := false"

这些是文件夹根目录build.sbt的默认内容：

name := "computer-database-sample"
PlayKeys.playOmnidoc := false

在PlayKeys调用之前，我尝试将以下行添加到build.sbt以显式导入播放屏幕：

libraryDependencies ++= Seq(
    "com.typesafe.slick" %% "slick" % "2.0.0",
    "com.typesafe.play" %% "play-slick" % "0.6.0.1",
    "com.typesafe.slick" %% "slick-extensions" % "3.1.0"
)

但我仍然遇到同样的错误。

我错过了什么吗？这是一个scala项目的设置方式吗？

Answer 1

停止正在进行的任何修改，还原它们（你需要从repo获得干净的版本）。

执行以下操作（不是最快的根，但是允许您随意探索其他方面的内容）：

1）转到repo根目录。

2）输入：sbt - 我没有工作，先安装sbt

3）成功完成第2点后，您应该看到以下几点：

[pdolega@maracuja play-slick]$ sbt

[info] Compiling 1 Scala source to /home/pdolega/projects/slick/play-slick/project/target/scala-2.10/sbt-0.13/classes...

[info] Set current project to play-slick-root (in build file:/home/pdolega/projects/slick/play-slick/)

＆GT;

4）输入：projects。您将看到所有sbt子项目：

> projects
[info] In file:/home/pdolega/projects/slick/play-slick/
[info]     basic-sample
[info]     computer-database-sample
[info]     docs
[info]     iteratee-sample
[info]     play-slick
[info]     play-slick-evolutions
[info]   * play-slick-root
[info]     samples
>

4）键入project computer-database-sample＆lt; - 这将使您想要的子项目处于活动状态。

> project computer-database-sample
[info] Set current project to computer-database-sample (in build file:/home/pdolega/projects/slick/play-slick/)
[computer-database-sample] $

5）现在你可以安装do test来运行编译和之后的所有测试。或者您可以输入run来启动此示例Play应用程序。

[computer-database-sample] $ run
[warn] Credentials file /home/pdolega/.bintray/.credentials does not exist

scala：运行Play-slick示例会导致导入错误
