This appears to be happening because Windows paths use \ rather than /. In the generated file compiler\closure_compiler_sources.gypi the backslashes are not escaped.

In the file compiler\generate_source_list.py, change line 56 from:

''' out.write(" '%s/%s',\n" % (self.path, filename))'''

to:

''' out.write(" '%s/%s',\n" % (self.path, filename.replace('', '/')))'''

This will allow the sync to complete.

I actually had a fix for this on my Windows VM; but the build will continue to fail after this step. I'll will revive my VM and look into it.

compiler issue solved in r711

There are other issues (e.g. #­209) that need to be addressed.
