Question

当我在一个项目目录上运行sbt时，它会在启动时发出Detected sbt version 0.12.1。

键入about并重复该版本。

但是，在另一个项目目录中运行sbt会将其版本标识为0.11.3。

即使在同一终端会话中也会重现。版本因项目目录而异。找不到会导致此问题的build.sbt文件中的任何显式部分。

有什么可以解释这个？

在我的情况下，我想在两种情况下使用sbt 0.12.1，如何强制该版本也用于后期项目？

该项目是一个SBT多项目，由于每个子项目都是一个单独的项目，您可以使用project/build.properties设置不同版本的SBT。该命令只是项目特定的。

sbt版本因项目目录而异，在同一操作系统上
