Setting current working directory when executing a shell process

Question

I would like to call sbt update within my source-code, to update multiple sbt projects. In the shell this is easy:

cd /path/to/project &&         


        

Answer 1

Use one of the ProcessBuilder factory methods on the Process object:

sys.process.Process(Seq("sbt","update"), new java.io.File("/path/to/project")).!!

For more documentation, see the scaladoc file for the sys.process package. Unfortunately, it does not mention the 'current working directory' arguments, but they are in the documentation of object Process.
