问题 I have an eclipse workspace (for work) that has an ear project that I use to "export"/deploy an ear file to a JBoss server. However, they recently asked me to create an ant script that can build the workspace and create the ear, and I have done this successfully.

问题 I'm googling without success to figure out how to make ANT print System.out.println/System.out.print messages in the console. Messages simply don't appear.

问题 I'm doing PHP development and I'm thinking of using one of these. I have both PHP and Java installed on my machine. In theory I could use any of the two. What are the compelling arguments to pick Phing over Ant? 回答1: The greatest argument I have in favor of Phing is that it's fully developed in PHP ; which means, at least : You can debug it / submit patches if you want You can develop tasks in PHP including tasks which are specific to your project that can use stuff from your project (I've
