Is it possible to call Ant or NSIS scripts from Java code?

Question

Is it possible to call Ant or NSIS scripts programmatically from Java code at runtime? If so, how?

Answer 1

Too expand on Nivas' answer - his solution is correct, you are not seeing output from your program because you haven't attached any loggers to your project.

DefaultLogger consoleLogger = new DefaultLogger();
consoleLogger.setErrorPrintStream(System.err);
consoleLogger.setOutputPrintStream(System.out);
consoleLogger.setMessageOutputLevel(Project.MSG_INFO);
p.addBuildListener(consoleLogger);

This is just basic setup, theres alot more you can do with the Ant Java API.
