Two things: Ant will show the task as being executed, but may not actually carry out the task. For example, you may see a task <copy> being executed when you have the debug flag on, but the copy itself might not be done. Of course, a target will always be executed even if the tasks in it don't have to be executed.
Some tasks (due to the way the task was programmed) will execute even if it doesn't have to. For example, in old Weblogic bean creations, the bean would be recreated even if the *.java files weren't modified. To get around this problem look at the "uptodate" task. This task allows you to set a property if a particular set of files have a timestamp that's newer than a particular source file. Then, you can define a target to run if the property is set or not set. If you use the Ant Contrib tasks, you can use the "outofdate" task which is very similar to the "uptodate" task, except that the "outofdate" task allows you to define a set of tasks to execute when the outofdate condition is met. These tasks can be run either sequentially or in parallel. See <http://ant-contrib.sourceforge.net/tasks/tasks/outofdate.html> for information on the outofdate task and <http://ant.apache.org/manual/CoreTasks/uptodate.html> for the "uptodate" task. Remember that the "outofdate" task is only good if you have the antcontrib tasks included in your task library. On 24 May 2007 11:46:03 -0000, query <[EMAIL PROTECTED]> wrote:
Earlier I was using some other build tool to build my project. Here if a target is built and if the same target is used to build some other target, it compares the timestamp and will not build the dependent targets again. As I started working on ANT, I found it very useful and intersting. But in ANT, while building each target, it will try to build all the dependent targets that many times as it occurs in different targets. As a result it is increasing project\'s build time.Is there any task to ensure that the dependent targets once built will not be built again ????
