- SBT 1.02
- 斯卡拉2.12.3
- 的Java 8
- Ubuntu Linux操作系統的16.04上的ThinkPad &的Mac OS X塞拉利昂（10.12.6）
我採取的步驟：
- 在這裏使用說明在Linux和Mac上安裝了SBT：http://www.scala-sbt.org/1.x/docs/
- 創建Hello World示例。
- 試圖在SBT和bash命令行中運行示例程序。
- 觀察發現，不管是什麼我試過設置，我仍然會看到調試消息：
這裏有一個例子：
Osiris:hello Noel$ sbt
[info] Loading project definition from
/Users/Noel/src/scala/sandbox/hello/project
[info] Loading settings from build.sbt ...
[info] Set current project to Hello (in build
file:/Users/Noel/src/scala/sandbox/hello/)
[info] sbt server started at 127.0.0.1:5256
sbt:Hello> logLevel
[info] warn
sbt:Hello> run
[info] Running example.Hello
hello
[debug] Waiting for threads to exit or System.exit to be called.
[debug] Classpath:
[debug] <abbreviated>.../hello_2.12-0.1.0-SNAPSHOT.jar
[debug] <abbreviated>.../scala-library.jar
[debug] Waiting for thread run-main-0 to terminate.
[debug] Thread run-main-0 exited.
[debug] Interrupting remaining threads (should be all daemons).
[debug] Sandboxed run complete..
[debug] Exited with code 0
[success] Total time: 0 s, completed Oct 15, 2017 9:44:13 PM
sbt:Hello>
我的嘗試：
- 從命令line： sbt warn run
- SBT內： warn 運行
- 修改build.sbt包含線路： 日誌等級：= Level.Warn
這裏是build.sbt樣子：
import Dependencies._
logLevel := Level.Warn
lazy val root = (project in file(".")).
settings(
inThisBuild(List(
organization := "com.example",
scalaVersion := "2.12.3",
version := "0.1.0-SNAPSHOT",
)),
name := "Hello",
libraryDependencies += scalaTest % Test
)
我也搜索過此論壇，但這個問題在4年前被問及，這些答案不適合我。我錯過了什麼？
在此先感謝。
