Well, duh.

Except you forgot to switch to Windows nomenclature ("D:/", not "/cygdrive/d/").

You need the quotes because bash sees the semicolon as a statement terminator.  Remember?  You could also have escaped the semicolon with a backslash instead of using quotes.

You need the asterisk for the reason stated upthread.  Did you review the rules for classpath specification as two respondents suggested?  It's very basic stuff - the JARs must be called out explicitly, or since recently with a wildcard.  You don't pick up JARs just by listing the directory.  As stated in the tutorials and documentation.  Which you should study.

Well, duh.  Did you read the answer upthread for that?  Someone already explained this to you.  You should read the answers that people here generously provide for free at your request.

"java" is a Windows program.  It does not recognize Cygwin paths.  Again we tell you.

You even got a link upthread for the "java" command and how it takes parameters.  You should read the answers that people here generously provide for free at your request.  And the Java documentation.
