为了在构建项目时真正强制使用SBT版本，您应该在project/build.properties文件中指定该版本。下面是我的项目中这个文件的内容：

sbt.version = 1.0.4

如果我导航到根项目文件夹并运行sbt about，它会显示

[info] This is sbt 1.0.4
[info] The current project is {file:/ssd2/projects/ADMP/}admp 1.0
[info] The current project is built against Scala 2.11.9

如果将build.properties中的版本更改为

sbt.version = 1.0.1

[info] This is sbt 1.0.1
[info] The current project is {file:/ssd2/projects/ADMP/}admp 1.0
[info] The current project is built against Scala 2.11.9
