Classpath too long to run exec command on Windows

[jihry]

Trying to use FileUtils.execDeleteRecursively when error occurred complaining about the size of the line. This is on a Windows system. Getting the classpath variable from the System results in a very large path for my project; however this command doesn't need all of the loaded jars. It may be sufficient to use:
String classpath = DeleteRecursively.class.getProtectionDomain().getCodeSource().getLocation().getPath();
