问题是为什么要打印 sbt 版本 0.13.15 而不是 1.0.4 ?.我使用的是 Windows 8.

推荐答案

为了在构建项目时真正强制执行 SBT 版本，您应该在 project/build.properties 文件中指定此版本.这是我项目中这个文件的内容:

In order to really enforce SBT version when building your project you should specify this version in the project/build.properties file. Here is the content of this file in my project:

sbt.version = 1.0.4

如果我导航到根项目文件夹并运行 sbt about 它会显示我

If I navigate to the root project folder and run sbt about it shows me

[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

如果我将 build.properties 中的版本更改为

If I change the version in the build.properties to

sbt.version = 1.0.1

然后运行 ​​sbt about 它显示我

and then run sbt about it shows me

[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

SBT 知道如何加载特定版本的源，如果当前版本的 SBT 不同，则加载它们，编译该版本的 SBT，然后使用该版本的 SBT 构建您的项目.

SBT knows ho to load particular version sources, loads them if current version of SBT is different, compiles that version of SBT and then builds your projec with that version of SBT.

为什么它在您的情况下默认显示 0.13.15 - 我不确定.可能在您的项目中，您在 build.properties 中指定了该版本，可能是出于其他一些原因.

Why it shows by default 0.13.15 for your case - I am not sure. Probably in your project you have that version specified in the build.properties, probably for some other reasons.

尝试在 sbtVersion 任务的帮助下检查.运行命令 sbt sbtVersion.

Try also check with help of sbtVersion task. Run the command sbt sbtVersion.
