sbt为什么不创建项目文件？
|
我试图在Macbook上安装SBT。当我运行它时，它不会询问我任何项目定义（例如标题），只是说
[info] Set current project to default (in build file:/Users/qui/Documents/Programming/test2/)
没有找到相关结果

This command does not rebuild the build definitions, plugins, or configurations. It does not automatically persist the setting(s) either. To persist the setting(s), run \'session save\' or \'session save-all\'. If \'every\' is specified, the setting is evaluated in the current context and the resulting value is used in every scope. This overrides the value bound to the key everywhere. [test2]> set scalaVersion := \"2.10.3\" [info] Defining *:scalaVersion [info] The new value will be used by *:allDependencies, *:dependencyUpdatesData and 11 others. [info] Run `last` for details.

[info] Set current project to test2 (in build file:/Users/jacek/sandbox/stackoverflow/test2/) [test2]> scalaVersion [info] 2.10.3命令设置其他设置。文件将包含所有设置，就像首先在此处进行设置一样。默认情况下，sbt在目录中创建各种文件。当您查看目录时，没有文件-只是一个空目录。同样的内容适用于可能也可能不包含目录的。假定它们可用，如果没有，默认情况下会创建它们。 当您在sbt \的交互式外壳程序中更改设置（使用）时，可以使用保存会话。[test2]> help session session <command> Manipulates session settings, which are temporary settings that do not persist past the current sbt execution (that is, the current session). Valid commands are: clear, clear-all Removes temporary settings added using \'set\' and re-evaluates all settings. For \'clear\', only the settings defined for the current project are cleared. For \'clear-all\', all settings in all projects are cleared. list, list-all Prints a numbered list of session settings defined. The numbers may be used to remove individual settings or ranges of settings using \'remove\'. For \'list\', only the settings for the current project are printed. For \'list-all\', all settings in all projets are printed. remove <range-spec> <range-spec> is a comma-separated list of individual numbers or ranges of numbers. For example, \'remove 1,3,5-7\'. The temporary settings at the given indices for the current project are removed and all settings are re-evaluated. Use the \'list\' command to see a numbered list of settings for the current project. save, save-all Makes the session settings permanent by writing them to a \'.sbt\' configuration file. For \'save\', only the current project\'s settings are saved (the settings for other projects are left alone). For \'save-all\', the session settings are saved for all projects. The session settings defined for a project are appended to the first \'.sbt\' configuration file in that project. If no \'.sbt\' configuration file exists, the settings are written to \'build.sbt\' in the project\'s base directory. [test2]> session save [info] Reapplying settings...

最后，我相信在没有任何参数的情况下启动的SBT应该与该脚本完全一样。
