Question

如何抑制SBT的调试信息？它们被记录到stdout，因此运行一个项目产生了这个：

$ cat src/main/scala/Hello.scala 
object Hello {
  def main(args: Array[String]) {
    Console.println("Hello sbt")
  }
}

$ sbt run > out.txt

$ cat out.txt
[info] Set current project to hello (in build file:/home/synapse/projects/algs2/)
[info] Running Hello 
Hello sbt
[success] Total time: 1 s, completed May 14, 2013 11:39:23 PM

Answer 1

正如this reference中提到的另一个答案所链接的那样，可以在到达sbt控制台之前更改日志记录级别。

＆＃34;要在启动时执行任何命令之前设置日志记录级别，请在日志记录级别之前使用public void createTables(SQLiteDatabase database) { String subscriber_table_sql = "create table " + Database.SUBSCRIBE_TABLE_NAME + " ( " + Database.SUBSCRIBE_ID + " integer primary key autoincrement," + Database.SUBSCRIBE_NAME + " TEXT," + Database.SUBSCRIBE_PHONE + " TEXT," + Database.SUBSCRIBE_DEVICEID + " TEXT," + Database.SUBSCRIBE_AREA + " TEXT," + Database.SUBSCRIBE_CITY + " TEXT)"; String friends_table_sql = "create table " + Database.FRIENDS_TABLE_NAME + " ( " + Database.FRIENDS_ID + " integer primary key autoincrement," + Database.FRIENDS_NAME + " TEXT," + Database.FRIENDS_PHONE + " TEXT," + Database.FRIENDS_AREA+ " TEXT," + Database.FRIENDS_CITY + " TEXT)";。＆＃34;

例如

--

但是，您仍然会在最后记录$ sbt --error "runMain my.pckg.Main"消息。为了使其沉默，请考虑使用[success]。

Answer 2

您可以按照here所述更改日志记录级别。因此，您可以将日志记录级别更改为Warn：

> run
[info] Running Server
Port is: null
Embedded server running on port 8080. Press any key to stop.

>
> set logLevel in run := Level.Warn
...
[info] Reapplying settings...
[info] Set current project to server (in build file:/Users/me/myproject/)
> run
Port is: null
Embedded server running on port 8080. Press any key to stop.

并且您不再获取为run命令打印的信息消息。您可以将该设置添加到构建文件中，以使其永久化。

Answer 3

您可以将“日志级别”属性添加到“全局SBT”属性。这适用于sbt版本1.x

档案：

$result = DB::table('fixtures')
        ->join('games', 'fixtures.homeId', '=', 'games.dataId')
        ->select(DB::raw('fixtures.id','fixtures.homeId','fixtures.awayId','games.name','games.id'))
        ->where('games.parent', null)
        ->get();
return($result);

~/.sbt/1.0/global.sbt
