So any libraries included with Ant, and any libraries available to ant, are automatically in your build's classpath whether you like it or not. It was decided that this probably wasn't what most people wanted. So now there's an option for it. > Is it important? Yes. It calls your attention to an issue that can make your builds to work in unexpected ways. For an example, see item #3 at http://blogs.sun.com/kto/entry/painful_ant_bite_a_generous. If you choose "true", then at least you know that your build classpath will include the Ant runtime. If you choose "false" then you are accepting the fact that the build behavior will change between older versions and 1.8+. > Who needs to know? I don't care. If you want your build file to have total control over your build, then you should care. > Why doesn't Ant just default to false and just omit warning me about this for every Ant build? > I don't want adjust every build file that I have. There are probably other ways, but it's annoying anyhow. As annoyed as you are to see this warning, you'd be even less happy if your builds broke entirely. Keeping this default behavior allows unmodified build files to work consistently between versions of Ant. -- Chet --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscribe@ant.apache.org For additional commands, e-mail: dev-help@ant.apache.org
