1162343 - `mach mochitest-plain` broken on Windows

Status: RESOLVED WORKSFORME

(Firefox Build System :: Mach Core, enhancement)

Description

[Chris Pearce [:cpearce (Not reading bugmail)]]

It appears that `./mach mochitest` is broken on Windows 8.1:


$ ./mach mochitest-plain dom/media/test/
Error running mach:

    ['mochitest-plain', 'dom/media/test/']

The error occurred in mach itself. This is likely a bug in mach itself or a
fundamental problem with a loaded module.

Please consider filing a bug against mach by going to the URL:

    https://bugzilla.mozilla.org/enter_bug.cgi?product=Core&component=mach


If filing a bug, please include the full output of mach, including this error
message.

The details of the failure are as follows:

ImportError: cannot import name MochitestArgumentParser

./mach build and ./mach build binaries is still working. The same test commands work on my MacOSX 10.10 MBP.

A clobber fixed it. My build must have been stale somehow, or I'd clobbered without building or something. -> User error.
