cygwin and Jenkins/Hudson issue

[Z W]

Hi All

We installed cygwin on a 64 bit Windows Server.
We tried executing a simple *nix command on the build step "Execute
shell" but we're getting error below.
We set the environment variables in PATH of the windows box with
C:\cygwin\bin and still it doesnt help.
We also have installed cygwin plugin of Jenkins and it still didnt help

What are we doing wrong ?

Thanks for your hints and suggestions.


FATAL: command execution failed
hudson.util.IOException2: Failed to locate Cygwin installation. Is
Cygwin installed?
