I'm working with Ant and one question have been faced. It's seems clear to set a base directory to project you need to use 'basedir' property in 'project' tag. But how could I set the basedir only for 'target'? I need to write build.xml with a target to launch application from any directory. That application loads a file with a relative path. Thus, I should set the base directory to root of that application. Thank you.
