That's exactly the kind of thing I was looking for; thanks! Now, to figure out how to set my own, from a file.

I've pasted the contents of maven.xml below, at the bottom of the message. Basically, the idea was to have 3 goals: live1, live2 (identical except for server names--we run the app on a small cluster), and dev. Each has its own property file, which is loaded into Maven's properties, and then used to fill in various tokens in config files. It seems like "goals" are gone in Maven 2, so I'm trying to replace that idea with different profiles, but I'm encountering a couple of problems in the conversion. -Questions First, is there a comprehensive list of the tokens that are automatically set in Maven 2? I'm talking about things like ${basedir}, which is the only one I've been able to uncover so far, that maven assigns values to without needed to read them from a file somewhere. I'm loooking especially for a Maven 2 equivalent to ${maven.war.webapp.dir}, which apparently was set in the Maven 1 war plugin, but not in the Maven 2 version. I assume it's still there, but I don't see anything to indicate what it's called now. Second, as I mentioned, the old goals loaded their particular properties files into Maven. This is where things like ${email.reports} come from in the copy/paste below. It seems to use ant:run to load the files that way, which apparently brings the properties into Maven (not Ant)? That seems strange and unintuitive, but that's the impression I get. The same peculiar behavior does not appear to happen when I use Maven2's ant:run to perform the same task. So, is there a way to get Maven to read a standard Java properties file and make those available for ${} tokens? Note that I cannot use <filter>, because I need those substitutions available in pom.xml Thanks, Dan Allen -The file I'm trying to convert <?xml version="1.0" encoding="UTF-8"?> <!-- Old Maven 1 maven.xml file.
