Project name in build.xml is case sensitive and fails poorly

Windows file structure is not case-sensitive, but Java
itself is. So if you put one Sheets file name (say,
"J2SSH.sheets" in the build.xml and the file name is
actually "j2ssh.sheets" and the actual project is named
that, it fails poorly, with the following exception and
no error message for the user explaining how to fix it:

$ ./ant.bat opendev
Buildfile: build.xml

init:

opendev:
Launching sheets...
