Running ant in loop mode
Once in a while I work in a Java project where I need to run a simple Ant task many times in a short period of time. Like web projects where the JSP files are located in a directory under source control and are deployed in another directory by an Ant task. If I change a JSP file, I need to run Ant again, and it takes an eternity (about 5-6 seconds), due to the overhead of running the JVM, reading the XML files, etc...
