Cannot handle directory with spaces

[JordenVerwer]

When I run mvn vagrant:up -X in a project directory with spaces in the path, I see that the plugin tries to execute the following command:

[DEBUG] Execute:Java13CommandLauncher: Executing 'C:\Program Files\Java\jdk1.7.0_17\jre\bin\java.exe' with arguments:

The jruby.home argument has been split on the path space. This makes the command fail.
