Build fails if file/directory paths contains whitespaces

[Steve-0628]

Describe the bug rush build doesn't work on macos

To Reproduce Steps to reproduce the behavior:

1. Make a project
2. Run rush build to build it
3. Get an error

Expected behavior It should be built, as nothing is changed.

Screenshots (Sorry for the japanese screenshot)

javac: Support/.../classes is an invalid flag. 
Usage: javac <options> <source files>
Use -help to view all options

Desktop (please complete the following information):

• OS: macOS Big Sur 11.4 (20F71)
• Rush Version v1.2.4

Additional context It seems like it is using "Application Support" folder which contains space in it, so javac is complaining about it.

Thanks for reporting this. Yes, you're correct, javac is complaining because of the whitespace in the directory path. Here's a workaround until I ship a new release fixing this:

1. Copy/Move everything inside the Application Support/rush directory to a place whose path has no whitespace. For e.g., /home/rush.
2. Then, export the RUSH_DATA_DIR environment variable and set its value as the path of the previously moved directory.
3. Build your extension with rush build.
