如何使用批处理文件构建多个项目（Maven和Scala）

Question

我正在尝试使用Windows批处理文件一个一个地构建Maven项目以及Scala项目。 为此，我在根文件夹中创建了一个批处理文件，并在其中写了以下几行。 虽然我的Maven项目正在成功构建，但是scala项目却未能构建。

call mvn -f A/pom.xml clean install -U
call sbt B\build.sbt clean compile -U
call mvn -f C/pom.xml clean install -U
call sbt D\build.sbt clean compile -U

我得到的错误是：

[warn] Executing in batch mode.
[warn]   For better performance, hit [ENTER] to switch to interactive mode, 
or
[warn]   consider launching sbt without any commands, or explicitly passing 
'shell'
[info] Set current project to my project(in build file:/C:/sample-
project/MyProject/)
[error] Expected ID character
[error] Not a valid command: B
[error] Expected project ID
[error] Expected configuration
[error] Expected ':' (if selecting a configuration)
[error] Expected key
[error] Not a valid key: B
[error] B\build.sbt
[error]            ^

以下为我工作...

cd A
call mvn clean install -U
echo Completed building A
cd ..
cd B
call mvn clean install -U
echo Completed building B
cd ..
cd C
call sbt clean compile -U
echo Completed building C
cd ../
cd D
call mvn clean install -U
echo Completed building D
cd ..
cd E  
sbt clean compile
echo Completed building E
