Problem building openjdk using cygwin

[Volker Simonis]

Hi Alireza,

sorry if my answer (and especially the link which I provided) have been
unclear. You don’t have to create any junctions. You just have to enable
short (i.e. „8.3“ filenames) for the drive /directory where you have
installed Visual Studio. Afterwards you must copy “microsoft visual studio”
to a temporary directory and finally copy it back to “microsoft visual
studio”. This should create a short name for that directpry.

You can find more information about how to enable/disable short filenames
here:

Volker
