           Summary: ant.bat execution fails if CLASSPATH ends with double-
                    quotes
           Product: Ant
           Version: 1.7.0
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: normal
          Priority: P3
         Component: Wrapper scripts
        AssignedTo: dev@ant.apache.org
        ReportedBy: dim.242@gmail.com


If the CLASSPATH environment variable ends with a " (double-quote character),
then the Ant scripts will not work; the error message is "The syntax of the
command is incorrect.".
This is due to the line 82 in the script file ant\bin\ant.bat:

if not _%CLASSPATH:~-1%==_\ goto findAntHome

Indeed, variable expansion+manipulation here results in this:

if not _"==_\ goto findAntHome

which obviously breaks the syntax of the shell.

A quick fix is
* either to remove the double-quote characters around the last CLASSPATH entry
* or to add an additional semi-colon ( ; ) character at the end of your
environment CLASSPATH value
