This tells me that "Cygwin" is in C:\Tools\Cygwin\bin; it also tells me
that cygwin1.dll is that directory, as "which" can be invoked ...

And bash is also found in C:\Tools\Cygwin\bin, I believe. (which can be
verified by "where bash").

Consequenly Cygwin's bash can be invoked (even from a Windows JVM). It
does not matter that Runtime.exec calls ::CreateProcess.

I have no idea what "build" is or does ...

Apparently, it refers in some way to the WSL executables ...

As Windows JVM is not installed at my place (and I am using W7, where
WSL cannot be installed), I cannot help you forward beyond this point.
