问题
I have build.properties file in the project with the following line:
sbt.version=1.2.8
build.properties file is in the same folder as build.sbt file.
But when I enter the command "sbt about", it reports 1.0.3. Following is the actual output of the command:
/Users/kale> sbt about
[info] Loading settings from idea.sbt ...
[info] Loading global plugins from /Users/kale/.sbt/1.0/plugins
[info] Loading settings from plugins.sbt ...

[info] sbt, sbt plugins, and build definitions are using Scala

How can I change sbt version to 1.2.8?
回答1:
your project structure should be <root>/project/build.properties, and then you should change the sbt version property (see https://github.com/pedrorijo91/play-slick3-steps/blob/master/project/build.properties as an example)
Use sbt about to know the version in use.
